  • jVangsnesjVangsnes

    where's the c++ based introduction? :(

  • CharlesCharles Welcome Change

    @jVangsnes: It will come! I've been underwater busy and dropped the ball on this (to meet today's release...).

    We WILL be releasing C++ Windows Store App dev tutorials in the near future on Channel 9.

    C

  • jVangsnesjVangsnes

    Really good to know. Thank you!

  • Awesome!

  • said barchilsaid barchil

    wow thank you so much
    :)

  • GijsGijs

    Why no VB???

  • ZawlZawl

    what is the better language? C++ or C#? I am really looking forward to making an app for the windows store

  • Abdelhamida_derrar MSP

    thank you, very helpful content Wink

  • Andrew Richardswindev Andrew Richards

    Just watched all 34 episodes back-to-back. (Power was out in the office so I thought I'd make the most of the day).

    Wow, what a great series. I'm a Win32 C++ guy, with little UI or C# experience, and I followed along easily with all the concepts Bob presented. I'm enthused to write my own app now - just need an idea... Maybe something to do with my series "Defrag Tools"? Tip of the day/week perhaps?

    Thanks Bob!

  • @windev: /bows ... that's quite a feat!

    @Zawl: Well, personally I never think in terms of "better".  Are you already adept at C++ or more comfortable with C# including syntax, tools, concepts, etc?  That's how I would decide.  I'm not sure there's a great technology reason to choose one or the other -- they both utilize WinRT.  (I could be wrong.)

    @Gijs: There's no VB version of the Contoso Cookbook HOL, so the team decided -- instead of writing that Lab ourselves -- to just use what's already there.  My personal comments here: While I began with VB, I haven't seen a lot of docs / videos / articles / books using VB for Win8 or other recent technologies.  Increasingly, it feels to me *personally* like C# would be a good investment.

  • Andrew Richardswindev Andrew Richards

    @BobTabor: BTW, it takes about 14hrs to go through it all (with some replays and breaks)... I started at 8am and ended after 10pm. Only had a short lunch and dinner and took a few phone calls -- so all-in-all, about 11-12hrs of training.

  • Bob, fantastic introduction! I've downloaded the Camp in a Box, and am looking very forward to jumping in. Keep up the great work!

  • Very good, I was surfing in channel 9 looking for a good documentation about XAML and C#.

  • MaloniMaloni

    thank you Bob, I am continue

  • radrad

    The URL seems correct but when you get on the site, you get automatically redirected to the general Visual Studio site, where they actually only show the paid Visual Studio editions. You have to use the search function to be able to download the Express edition, it's like their hiding it.

    Any idea why is that? Are they planning to remove express edition altogether ?

  • jms429jms429

    Bob,
    your like sesame street for our community. thank you for existing!

  • @rad: Microsoft continues to support the Express Editions with the latest release of Visual Studio 2012.  This URL should *always* point to the latest versions:

    http://microsoft.com/express

    ... and there's always bing.com  Smiley

    @jms429: Hmm... thanks?  Smiley

  • NishantNishant

    As you said in this first lect that one will get error on "callisto" i removed it first and installed as shown in video but then i got a following error. Please let me know how to resolve it ? And i am using Express edition of VS 2012 for windows 8 and running release preview of windows 8.

    Warning 1: Because this call is not awaited, execution of the current method continues before the call is completed. Consider applying the 'await' operator to the result of the call. File:C:\Win8CS\Demos\02 - ContosoCookbook XAML\Source\ContosoCookbook\App.xaml.cs Line no.:138 ContosoCookbook

    Error 2:The type or namespace name 'WindowCreatedEventArgs' could not be found (are you missing a using directive or an assembly reference?) File:C:\Win8CS\Demos\02 - ContosoCookbook XAML\Source\ContosoCookbook\App.xaml.cs line no:284 ContosoCookbook

    Error 3:'Windows.UI.Xaml.Application' does not contain a definition for 'OnWindowCreated' File:C:\Win8CS\Demos\02 - ContosoCookbook XAML\Source\ContosoCookbook\App.xaml.cs line no.:288 contosoCookbook

  • @Nishant: The first is just a warning, and can be ignored.  The second two errors are worrisome.  Just to be clear, you're talking about these lines of code (App.xaml.xs, lines 284 and 288 respectively), correct?

            protected override void OnWindowCreated(WindowCreatedEventArgsargs)
    

    { _dispatcher=args.Window.Dispatcher; base.OnWindowCreated(args); }

    I don't believe this is related to Callisto.  This may be due to some changes made to the Contoso Cookbook example after this series of videos was recorded.  I would recommend this ... don't worry about this specific error -- I was merely illustrating the kinds of things you'll learn. Follow along with the labs and the videos from this point on and by building it from scratch, we will avoid (or isolate) the problems.

  • NishantNishant

    Thank You sir. And yes i was talking about about those line of codes.
    And again thank you for providing us with such great series.

  • Great video series as always, Bob Tabor. I'am lifetime member of LearnVisualStudio and TrainingSpot, and your videos are the best learning resource to start building knowledge around Microsoft technologies. Thanks from Mexico.

  • anishanish

    hi I'm unable to get a developers license , don't know what the problem is .I get the following error http://i49.tinypic.com/2vtt6ro.png any solution ?

  • @anish: Check this out:

    http://connect.microsoft.com/VisualStudio/feedback/details/727734/unable-to-get-developer-licence-for-windows-8-consumer-preview

    I think what works the best is near the bottom ... "just keep hitting retry".

  • ashish manglaashish mangla

    hello bob during practicing i am not able to get windows strore in new projects.

    i am using VS2012 on window7 ultimate.


    plese help me

  • @ashish mangla: Yeah, that was the first of four requirements I discussed in the video ... you must use Windows 8 to create Windows 8 apps.  Good luck!

  • ashish manglaashish mangla

    thanks sir

  • NibirNibir

    I'm getting error on line number 125. It says that 'NullReferenceException' was unhandled by the user code. Also some warning of 'not awaited'. Please help.

  • @Nibir: Can you paste in a few lines of code in and around line 125?

    re: not awaited warning ... yes, that's fine.  You can ignore those warnings.  Purely informational and not needed in this case.

  • Sorry I forgot to mention it. It's in App.xaml.cs

    if (profile.GetNetworkConnectivityLevel() == NetworkConnectivityLevel.InternetAccess).

    It shows that

    'NullReferenceException' was unhandled by the user code

    'Object reference not set to an instance of an object.'

  • @Nibir: Set a breakpoint on that line and hover over the profile object.  I'm guessing the issue is somewhere above these lines of code, perhaps even in another method that executes prior to this method.

    More importantly, I would recommend that you not worry about this.  My only point of loading it up in this video was to show you the functionality you'll create in the rest of the series.  If you followed the steps I took exactly (you saw me take them!) it should work.  If it doesn't then you may want to start over, watch what I do closely, and try it again ... or just begin in Lesson 2 and we can take it line by line and build it together.  Smiley

  • Thank you sir.

    I set a breakpoint on that line and it stops saying no source available.

    I'm not sure whether it's my internet connection problem or not, but my connection is working fine.

  • vishuvishu

    hello bob ,i am starting with the c# tutorials first but in the 2nd part you showed to build and console app in new project but in visual studio 2012 the option is not there..which option should i go for....???

  • vishuvishu

    @BobTabor
    hello bob ,i am starting with the c# tutorials first but in the 2nd part you showed to build and console app in new project but in visual studio 2012 the option is not there..which option should i go for....???

  • @vishu: Hi Vishu, if you want to create a Console application, you'll need a different version of Visual Studio Express, namely Visual Studio Express for Windows Desktop:

    http://www.microsoft.com/visualstudio/eng/products/visual-studio-express-for-windows-desktop

    As you know, this series uses Visual Studio Express for Windows 8.  A bit confusing, but basically the "for Windows 8" is exclusively used for building Windows Store apps.  Hope that helps.

  • i am  very sad that why did not i find this website earlier

    i am very excited about this free tutorial

  • Why is the video quality so horrible in full screen, no matter what video format I use. This is usually the case with other VS videos also.

  • @Ahmad Pirani: Please do this ... RIGHT-CLICK on the "High Quality MP4" link to the right of the video player, selected "Save As ..." and save the file to your desktop or preferred folder.  Once it's on your desktop, you should be able to watch in high def 1280x720 with crystal-clear clarity.

  • Ghazanfar KhanGhazanfar Khan

    I am having several red line error in recipedatasource when I am adding recipidatasource.Also sampledatasource does not changing.

  • Ghazanfar KhanGhazanfar Khan

    In setproperty,OnProperty change.
    It says that ContosoBoook.Data.RecipeDataGroup doesnot contain definition for setproperty etc ....Please help needed

  • @Ghazanfar Khan: I'm assuming that you're trying to do what I do and open up the completed version of the Contoso Cookbook and run it?  Is that correct?  If so, I really encourage you to not worry ... please just watch the features of the Contoso Cookbook that we'll build together in the remainder of this video series.  We'll build the entire application from beginning to end.  I only opened up the finished version to show you what we'll build.  Don't let the fact that you can't open it and get it working discourage you.

    If you really do want to try and get it working, you'll need to send me more details.  What did you do?  What did you try?  Which lines of code are throwing compilation errors?  Copy and paste the lines of code along with the explanations I asked for.  Honestly, I really encourage you to just stop this, watch the rest of the video, and start fresh in the next video by building a brand new project from scratch.  Hope that helps!

  • SqandrS_kandr Looking for C++ role.

    I vote for that!

    where's the c++ based introduction? Sad

  • @Sqandr: According to this post:

    http://blogs.msdn.com/b/jennifer/archive/2012/05/24/do-you-want-the-contoso-cookbook-and-other-windows-dev-camp-content.aspx

    ... and Jaime's tweet:

    https://twitter.com/jaimerodriguez/status/203565184793583616

    ... there *is* a C++ version of the Contoso Cookbook.  However, I haven't looked for it myself in the .zip files on this page:

    http://www.microsoft.com/en-us/download/details.aspx?id=29854

    Here's what I would say ... if you want that kind of training, Microsoft will definitely get it to you. HOWEVER you have to know where to post those types of requests.  The Channel9 / Microsoft staff doesn't monitor these threads as closely as I do ... you will need to get their attention by using the "Feedback" link in the footer of this page.  That gets to the right people and they will talk about it.  Also, directing that feedback to the people (above) via Twitter or Email (I'm not posting someone else's email here, but it's not hard to find) will get it noticed faster as well.  

    I'm sure there are lots of great C++ instructors out there, but I'm not one of them.  I've never touched C++ and probably never will ... just too much to learn in the managed / C# world to stretch out beyond that.  Best wishes!

  • how come we don't have this on learnvisualtudio.net been waiting for u to treat it

  • hey Bob!

    Thanks for the great lessons!

    I'm absolutely new to any programming language. but recently I've gone through your series for learning Visual Basic Fundamentals. I'm almost through it.

    I want to begin with your series for developing windows 8 apps using C# but the language that I am now familiar with is VB. Can I start with the series without learning C# or is it necessary for me to go through the C# fundamentals series even if I know VB?

    I have all the resources that you said are needed to start developing Windows 8 apps, including Visual Studio Ultimate 2012, Windows 8 pro.

     

  • @styx13: You can certainly try.  However, when it comes time to write code (and we will write a lot of it) unfortunately you'll be on your own.  To my knowledge, at the moment there's no VB version of the Hands on Labs that I'm basing this series on aimed at VB developers.  I would say this ... since you're pliable (you're just finishing learning VB through the fundamentals series) perhaps you should try C# instead.  A little investment now will give you a lot of benefit in the .NET world going forward.  Many books and examples on MSDN and Channel9 assume C# knowledge.  You might find that you prefer C# over VB, even if it appears to look a little intimidating (and that's only because no one has explained / demonstrated that it's no harder than VB).  Hope that helps a little!

  • Thanks Bob.

    I'll certainly start getting my hands dirty with C# now. I've already downloaded the whole C# fundamentals series and source code and I'm going to start with it right now.

    I would like to ask you one more thing. During and after the series lessons are there any exercises that I can follow to become proficient in writing code? because I'm not from computer science background and I know very little about softwares and applications(only enough for me to use them)

    Even during your VB lessons I tried my best to follow and learn all the concepts but couldn't figure it out by myself how and where to apply all those concepts.

  • @styx13: re: "During and after the series lessons are there any exercises that I can follow to become proficient in writing code?" .. that is a core feature of what I offer on MY website: http://www.LearnVisualStudio.NET ... please check it out!

    How to play audio file in suspended mode also when the app is suspended it should continue playing . It works fine when when app is onscreen but when i'am suspending it it stops why? and how to solve it?

  • ElicegreenElicegreen

    Hi Bob,
    Thank you for the wonderful videos :)
    I am new to the world of programing but I'm very interested in becoming one.
    I watched your C# fundamental series and understood everything.
    You recommend continuing with this series yet I'm having a very hard time following through.
    It feels like a big leap somehow.
    Also I thought that a better knowledge of c# would be needed to become a store app developer.
    Would further learning c# be helpful?
    I don't just want to know how to create my own apps but rather maybe get a job as a programmer.
    What would you advise? And if only a fundamental understanding of c# and learning this series is enough, how do you suggest I make it easier to understand this series?
    Sorry for the long comment :/

  • @Elicegreen: Thank you for the nice post and I totally understand your questions / concerns.  Let me address a few of them ...

    "Also I thought that a better knowledge of c# would be needed to become a store app developer.  Would further learning c# be helpful?"

    First, don't get discouraged ... admittedly, there are aspects of this that will seem very challenging.  (1) You don't need to know everything to get started (!!!), and (2) most of the C# specific things you'll encounter in this lesson have been covered in the C# Fundamentals series.  The challenge is that:

    -- There's other things that are introduced here that probably deserve an entire series of their own, like XAML and the Windows Runtime ... a series in isolation with smaller examples, not trying to build an entire app right away OR not trying to follow a hands-on lab.  We probably could have / should have started there, but Channel9 and Microsoft had a ton of that content already and we wanted to do something different.  Maybe we missed the mark a little.

    -- There's a lot of code to wade through.  At some point, there's no getting around the fact that programs will have a lot of code.  Not only do you need to be able to WRITE code, but (and no one is talking about this) you also need to be able to READ code.  I'm convinced the more you stare at a problem the more sense it will make.  If it's any consolation, I spent a week just walking through this Grid App Template, building my own examples until I developed a mental model.  There's no substitute for focused deep thinking.

    More learning (especially in regards to software development  is ALWAYS helpful.  I have been a student of software development for nearly 20 years and I still learn new things every day.  I set aside large portions of my work time and personal life to learning.  HAVING SAID THAT ... let me emphasize that you don't need to know a lot before you get started.  Get started now, have a goal in mind, make lots of mistakes (that's GOOD!!!  We encourage making mistakes! ... you know, as long as you learn from them.)  Having a project to build will push you in new directions you may not learn simply by following some course.

    I'd be remiss if I didn't say that -- if you feel like you need more training in C# with homework examples and such -- I have a 22 hour C# training series (plus other important stuff) on my own personal website.  In fact, there's a lot there that you may find helpful.

    "I don't just want to know how to create my own apps but rather maybe get a job as a programmer."  

    Ah ... now that's an entirely different matter.  This is MY opinion alone ... but most employers are not yet looking for Windows Store App developers ... at least, not yet.  They're looking for a whole different skill set around .NET and C#.  You need to decide ... will I primarily focus on becoming a web developer or a desktop / device developer?  Beyond the presentation (web or desktop / device) you'll need to learn about persistence (like, into databases) and writing business logic, and at a higher level, you'll want to learn about the fundamentals of application architecture.

    I'm living proof that you can become gainfully employed as a self-taught programmer.  You can teach yourself, but you'll need to be dedicated, self-motivated, and you'll need to get into the practice of spending nights and weekends -- any spare time -- teaching yourself what you need to know.  At the end of the day, we're all self-taught ... no one can cram information into your brain.  You'll need to do some hard thinking / work.  "That's why they pay you the big bucks."  Not many people (relatively speaking) are willing to do that.

    Feel free to followup this conversation.  I'd love to help whatever way I can.  Again, don't get discouraged.  You can't learn it all in a day / week / month or even year!  But that shouldn't stop you from trying.

    Best wishes!!!

     

     

  • Thank you so much for such a detailed response! Smiley

    I'm glad I asked this because now I realized that I could've focused on the wrong subjects.

    It's great to know that someone as professional as you (you must be really good in order to teach it to others) is also a self-taught programmer. It makes me so much more optimistic about succeeding in this.

    I was looking on your site and saw you had that core c# course you mentioned. I am going to subscribe to your site. Do you teach the other subjects I would need to learn to become a programmer (and hopefully get hired as one)? 

    If so, would you be able to help me in making a studying plan?

    I am very motivated to succeed in this. And willing to put all the time and effort. The only thing I feel that I really need and currently lack is some guidance. 

    Thank you so much again. On top of being a great teacher (and programmer I'm sure) you are a great guy!

    Sincerely, 

    Elice.

  • @BobTabor:I'm not sure if you're busy or you just missed my last post.

    Drawing you attention to it just in case Wink

  • Can't find anything that has to do with NuGet Package Manager when right-clicking ".NET for Windows Store apps".

  • @Elicegreen: Sorry!  I was finishing up another series for Microsoft.  I just now have been able to go through and answer about 200 messages.  Sad  The path is relatively straight forward and I would be happy to walk you through it should you want to move in this direction.  Please email me personally at: bob at learn visual studio dot net

    @Niner627428: Hi again!  I'm assuming you got past this ... but if you didn't, a bit more information would help me help you.  Could you reference the spot in the video where you're running into trouble.  Admittedly, I think Visual Studio has been updated twice (!!!) since this video was produced just 3.5 months ago, so there might be something different now.  Calling my attention to it would help me determine if there's something I need to add / remove to the instructions.  Thanks!

  • Thank You Sir ...

    Thanks Was Waiting For such a great tutorial from a long time .... I will try to complete this one .. because i don't have an internet connection because my parents are already paying my tuition and clg fees .I don't wanna burden them with more.. I take time to visit cyber cafe's and watch your videos and take down notes so I can do it when i reach home .. Smiley And I had a question for you just out of topic ..What are that blue lights blinking behind you ??? There are certainly distracting me ?? Tongue Out

  • @Amey023: Sorry for the distraction ... it's a binary clock.  Bonus points if you can tell me what time of the day I recorded this video.  Wink

  • ShadabShadab

    sir how we can increase or decrease number of tiles in groupItemPage. thnx

  • i also want to know that what should i include in apps documentation as i am developing app for my Computer Science degree, plz mention list of uml diagrams which should be included in doc. 

  • @Shadab: In an effort to keep this thread relevant, I would encourage you to check out Lesson 13 where I discuss the Grid App Template.  Ultimately, it's set in the StandardStyles.xaml ... you change the number of tiles by changing the size and other properties of the Grid.

    @ShadabHashmi: So, you paid all that money to get a CompSci degree and they haven't talked about documentation?  Hmm... If I were you, I would complain to your instructors.  To answer your question, in reality -- in the real world -- "it depends".  Some organizations are very formal and require everything to be documented a certain way.  Other organizations (I would venture to say *most* organizations) have no real sense of documentation.  

    Ultimately, the CODE is the documentation.  It's the model of the business.  Everything else tries to keep up with the code, but fails because it's hard -- nay, impossible -- to keep them in sync.  Honestly, unit tests and code cleanliness are the best and only real documentation that matter.  The unit tests will be sufficient training for new developers to come up to speed on the functionality of each method and class.  Everything else is just an approximation of what's in the source code.  I expect that some would reject that, but I speak truth on this matter.  Smiley

  • wow... i m very glad to see ur response Smiley ... i watched ur videos on youtube and now we are having 1 to 1 interaction ... really owsm Smiley 

    in SE course we studied about documentation and diagrams, but i feel that win 8 apps are different as compare to desktop database application, in which we build documentation consisting of objective, scope, etc then DLR, DFDs, Normalization, Use Case, state diagram, etc ... i was jst thinking of myself about documentation of contosocookbook. bcoz it doesn't have database so normalization can not be there, 

    its dfd would be very limited, all use cases will almost same ... so thts why i was confused, 

  • @ShadabHashmi: Yeah, I'm sure someone out there is still using UML for design.  Search for the term "Big Design Up Front" ... it's an "anti-pattern" meaning that we've gone down that road as a industry and it's not the solution some originally touted.  The industry as a whole has moved past Big Design Up Front (i.e., a bunch of UML and docs that no one actually uses ... a time waste) to a more agile approach.  That's not to say there are not pockets of resistance out there ... some hold on to the past like a security blanket.  But they have to answer to themselves and their team and their employer: what value is this?  What value does it add?  The prevalent thinking now is that it doesn't do a lot for you in the end.  Hope that helps!

    Hi Bob, I think this series are the best way to start for all beginners in programming. Im mexican, Im learning about C# and Windows Store Apps. keep doing that great job :D

  • @Jose Molina: Thanks Jose!  Good luck as you work through this series.

    thanks bob...

  • Just for anyone else who might hit this.. I downloaded campinabox, it asked me what I wanted to open the .htm in.. I thought to myself (normally I would do Internet explorer, but seeing we are coding in VS2012, I think I should pick that...  Then I sat for 5 minutes wondering why I got a code data page rather then the website... DuHHH!!!   Go with your instincts and assign it to IE or whatever your preferred browser happens to be..

    Glad I finally found this series Bob..  I saw a portion of it in the LearnVS website, then have been searching for it.. Glad it is a free series as I feared I would need to pay for it, but was willing to (If I ever found it)  as I love your teaching style.. 

  • hello, I've been going through the training kit (HOL) that is provided here.. been very helpful so far.  However, on lab 5 dealing with PLM.. i get an error after suspending/shutting down the simulator of the cookbook app and attempting to restart the simulator, and just a blank screen if launching the application directly within the simulator.

    I'm fairly new to all of this, and imagine that during the applications OnLaunched, it verifies if the rootFrame exists (which is doesn't after termination and a deferal had been created?), but to our demise, the LoadState method is failing because it does not have the context or handle to the data?  I'm not even sure I have a clue what I'm talking about here...

    I will try to set a breakpoint to the LoadState entry and watch what is happening there, but I really do not know what is wrong and especially how to fix it.

    any direction would be helpful to me understanding this... thanks!

  • @tswalker: Hmm... I don't know the answer specifically about the lab.  I would suggest trying this ... start with a fresh, brand new Grid App project, then try those same steps.  Is the result the same?  Do you get an error or not?

  • I'll give that a try today and let you know.. been watching the /build stuff here Wink

  • ok, so created a fresh grid app, suspend/shutdown and f5 restart works as expected...  not sure what's up with the lab 5 PLM example then..   /shrug.

    just fyi, also had problems in lab 6 with the 'remember' state stuff.. i'll try a fresh grid app for that as well and see if it is just something broken in the labs here.

  • ok, I realize now that the preference controls are all white on a white background.. >.<

     

    so, lab 6 was working, just couldn't see any of it.. no way to change the control colors very easily.  I guess this has something to do with Callisto.. dunno.

  • @tswalker: Yes, I thought I addressed all that mess in the video.  Maybe Callisto changed again since I recorded it?  It's definitely a "gotcha".  Sorry for the confusion!

  • Error when i debug the app:-The "GenerateAppxPackageRecipe" task was not given a value for the required parameter "ProjectDir"

  • @bavasanja: Hi, did you experience that while following along in this video?  If so, please don't worry about it ... we'll re-write the entire app from scratch in this video series.  If you experienced this problem while following along in this series, be sure to post this in the comments related to the video you were watching when it popped up so that can help me help you.  Thanks!

    @Bob
    I just want to know that What is difference between Windows Store App using C# and JavaScript?

  • @Adnan:  Besides the obvious syntax differences, they take a different path towards executing on your end user's system.  Luke Hoban does a nice job explaining this:

    http://channel9.msdn.com/Events/BUILD/BUILD2011/TOOL-533T

    I would say this ... from a practical perspective I don't believe there's anything that you can do with one that you can't do with the other.  At the end of the day, it's the common WinRT API that is making things happen.  It just depends on which language you feel more comfortable with.  If you're a JavaScript person, stick with JavaScript.  If you're a C# person, stick with C#.

    hi bob great video, I installed VS express on my windows 8 machine, opened the contoso cookbook project...got the Callisto error, opened reference and removed the Callisto..then tried to install itbut I got an error....

  • Clint RutkasClint I'm a "developer"

    @Anthony: callisto was updated for 8.1 and was a breaking change.  http://timheuer.com/blog/archive/2013/10/24/callisto-winrt-xaml-toolkit-windows-8-1-update-roadmap.aspx and https://github.com/timheuer/callisto/blob/master/changelog.md

  • AnthonyAnthony

    Hi, Clint
    Yeah found out about this hours later....so is there any way to get the contoso cookbook project to run on my windows 8 machine or I have to upgrade to 8.1......thanks for ur help u guys are awesome

  • AdrianoAdriano

    @Clint @Anthony: I don't think the problem is because you don't have the 8.1, because I have and it is happening the same problem.

  • AdrianoAdriano

    Should I be worried that others thing change in Windows 8.1, like Callisto, that I will have to pause the video and look for a different way to do that?

    Or we were just unlucky with Callisto, and the rest of the series, I don't have to change a thing?

  • Clint RutkasClint I'm a "developer"

    @Anthony and @Adriano: It has been a while since i looked at this sample.  Since you guys are mentioning Callisto, I think the issue is the cookbook took a dependency on Callisto.  Callisto was updated for 8.1 which had breaking changes.  Let me ping Dan Fernandez to see what he wants to do.

  • This series is a great introduction to building windows store app for Windows 8.0. With Bob Tabor proving to be an excellent teacher, who is able to relax the listener and explaining very well some complicated topics.

    However when you switch to Windows 8.1, a lot has changed even at the very beginning of creating a project and what you see in the common folder. LayoutAwarePage isn't used anymore and the handling of orientation changes is different, the structure of the DataSources is changed, the styling resources have changed. A lot of the complexity especially for a beginner is in understanding the basic structure and templates for a Windows Store App. And the changes for 8.1 confused me a lot when trying to follow this video series.

    It would be great for anyone like me who struggles on using this with the new Windows 8.1 template structure for building Windows Store App if there was a similar introduction focused on 8.1. I know there is an introduction tutorial for Windows 8.1 app (Create your first Windows Store app in C#), but that's not the same as this series (and the tutorial for blogreader is not updated to 8.1) 

    Are there any plans to do a similar video series on building for Windows 8.1?

  • @amit12x: Hi … I just want to make sure you heard me say this near the beginning of the video:  "First, you must have Windows 8 installed.  That's right, you can only building Windows 8 applications when running on Windows 8.  And frankly, that makes a lot of sense . . . You'll only get a real feel for the Windows 8 Metro Style application aesthetic and flow if you're using some of the built-in Windows 8 applications, so this will help you when designing the user interaction for your own application."

    ... and if you're a beginner, you may want to watch that series FIRST ... it will help you become more familiar with the basics of .NET and C#.  Good luck!

  • Hey there,

    first of all, I really enjoyed your previous series on C# - and I was going to give this series as go. However, reading through the comments, and the change log online I see that there are a lot of things that have changed in 8.1 for developers.

    So,- Here's my question: Is this series still useful for people who want to develop with c# and 8.1? It can become a bit confusing when you're a beginner when everything looks a bit different. So will there be an update for this course to 8.1? Even if you would point out the differences in the projects it would be very useful for beginners (like me).

    Thanks again for your great tutorials!

    Rince

    P.S: Jeff Proise posted a (long) article about what's new for developers in 8.1 where he also posted an updated solution for the Contoso Cookbook that will run when you are using Visual Studio 2013 and Windows 8.1

     

  • AnkitaAnkita

    So I installed callisto from the site mentioned and i tried to add it in the refrences when I went to windows->extension there was no option for callisto . Is there any other way that I can add it ?

  • Clint RutkasClint I'm a "developer"

    @Rincewind: Projects like this take a lot of time and planning.  To do a total difference between Win8 and 8.1 is something that is above an absolute beginner.

  • @Clint:Thanks for your response! Yeah, I can see how that would become a bigger project Tongue Out - Anyways It would be good if there was a short description like: "Yepp, with the 8.1 Framework there are a few differences - you can achieve the same as mentioned at (time) - when you do <<this>> .

     

  • Hey,

    I'd like to share my experiences with Callisto. I have VS 2013 installed (OS: W8.1). I have decided to download VS 2012 express to follow this series, but when I have tried to install the Callisto from Github (linked uppon), the VS installed it, but I think for VS2013, not for VS2012. I have found a way to install it for the 12, it's quite easy. You just have to copy the file into this directory: "C:\Users\YOURUSERNAME\AppData\Local\Microsoft\VisualStudio\11.0\Extensions" If you don't have this folder, then simply create it (I didn't have a 11.0 named folder, but I created it and then Callisto was installed in VS2012)

  • Calvin HeadleyCalvin Headley

    I noticed in the comments that a number of people where having issues with the conversion to Windows 8.1 for their apps. I too had difficulty with the Callisto assembly.

    Initially, I followed the video and simply removed Callisto from the references directory and then installed a new version via the managed nuget packages. This packaged failed to install and I discovered it was because I was running Windows 8.1 and not Windows 8. When I converted the application to Windows 8.1, I was able to install the Callisto. However, I then had a number of errors with the flyout object that was part of the Callisto Controls class. When I included the Callisto with the using statement at the top of the application, that also failed to work.

    using Callisto.Controls;
    using Callisto.Controls.SettingsManagement;
    using Callisto.Controls.Primitives;

    I finally had to change the new instance of flyout to a fully qualified path to the Callisto.

    Lines 264 and 277 have these statements:

    var settings = new SettingsFlyout();
    var settings = new SettingsFlyout();

    These caused the error. When I changed them to this:

    var settings = new Callisto.Controls.SettingsFlyout();
    var settings = new Callisto.Controls.SettingsFlyout();

    The errors resolved and I was able to run the application.

    Hope this helps.

    Do you know what to do or it is very complicated for me (as a beginner)?

    Hi Bob!!
    I just went through 1st 2 tutorials of the series and i m quite excited to complete this series and come up with new and creative ideas for windows 8 apps!!

    I would like to suggest you to use a compressor like handbrake etc to compress your high quality video(.wmv) files to smaller compressed files which would be economical and easy to download within less time.

  • and i just tried a software called "handbrake" which actually reduced the 255 MB tutorial video to 64 MB  without reducing the video quality at all!!
    i would recommend this one for your videos !! : ) : )

  • @bob This is a great series.  Thank you for your time and effort.  I know this has been asked more than once but I want to be clear on the answer:  Is this series relevant for windows 8.1?

  • ArjunArjun

    @bob tabor ; can we use visual studio 2013 ultimate instead of express edition...??

  • VedVed

    @BoB : Between C# + XAML vs JavaScript for windows app development,which one is better in terms of nativity and better APIs.
    What are the pros and cons or shortcomings in APIs provided.
    Which according to you is preferable for app development.

  • @rubot: Mostly, yes, however (a) the Contoso Cookbook example has not been updated, and (b) the dependency on the Calisto controls will be a problem.  Tim Heuer at Microsoft who maintains those controls (which the Contoso Cookbook relies on for a specific feature later in this series) has added breaking changes.  If you can work around that, this would still be a helpful series.

    Also, I'm no longer supporting this series ... it's been years ago since I recorded it and I'm just not as familiar with the material since I've moved on to other concerns.  Sorry!

    @Arjun: Yes, provided the caveats above.

    @Ved: I'm pretty sure it does not matter.  They have equivalent functionality.  It's really a matter of which language you're more familiar with.

    I have a desktop based java application which runs on Windows and Mac. The UI and Logic of that is well differentiated. Can I reuse the logic part(which will be a jar) and build the UI in an Windows 8 metro app ? Is it possible to talk to the Java layer ?

    In My Java app, I create an exe which bundles runtime(JRE) also to execute the Jar.

    I am new to Windows development and want to understand if I can create a bridge between this two layer.

  • Hello Bob, I have installed Visual Studio Express 2012 for Windows 8 and also downloaded the source code. At 14:06  you added Callisto NuGet for cook book. But when I am trying to install callisto NuGet, I am getting the following error:

    "Could not install package 'Callisto 1.4.0'. You are trying to install this package into a project that targets '.NETCore,Version=v4.5', but the package does not contain any assembly references that are compatible with that framework. For more information, contact the package author."

    Please help. Thanks!

  • @UsmanNasirKhan:

    I had the same problem and this is what I done. I updated everything on the Notifications and the Add or Remove Content. Then I used the Package Manager Console and type after PM>

    Install-Package Callisto -Version 1.2.4.

    This worked perfectly. Hope it helps.

    @Rob I fixed it. You could change target win 8.0 or win 8.1.
