LINQ Language Deep Dive with Visual Studio 2008

Beth Massi — Wed, 22 Jul 2009 05:13:00 GMT

Ever wonder what really happens when you write a simple LINQ query? A lot of new language features went into the compilers in Visual Studio 2008 to make LINQ work. In this interview I sit down with Jonathan Aneja, a Program Manager on the Visual Basic Compiler team, who dives deep into these features like Type Inference, Anonymous Types, Lambda Expressions, Expressions Trees, and more. He explains what's actually happening behind the scenes and all the work the compiler is doing for you when you write a LINQ query. My head almost explodes at the end but I learned a lot of important concepts. ;-)

Check out Jonathan on the VB Team Blog.

Enjoy,

MS Virtual Labs: Multi-Targeting in Visual Studio 2008

joelercoaster — Mon, 04 May 2009 22:40:00 GMT

Multi-targeting is a new feature in Visual Studio 2008 that allows developers to choose which .NET Framework they want to target for a given project. Available choices are 2.0, 3.0 and 3.5, and you may change your selection after a project has already been created. The IDE filters selectable features and the build system generates appropriate warnings based on whether a particular feature is available in the target platform.

The purpose of this demo/lab is to show how multi-targeting is implemented in Visual Studio 2008. The lab covers the following topics:

• Multi-targeting in the New Project dialog
• Target Framework-based filtering in Add New Item and Add Reference dialogs
• Target switching via project Properties dialog • Build- and compiler-generated errors and warnings based on Target Framework

endpoint.tv Screencast - Processing Message Content using HttpClient class

Cliff Simpkins — Mon, 30 Mar 2009 15:00:00 GMT

In this short video, CSD MVP Aaron Skonnard from PluralSight guides the viewer through different techniques for processing messages using the new HttpClient class that ships with the new WCF REST Starter Kit Preview 2.

In this screencast, Aaron builds on the simple Twitter command shell application started in the previous HttpClient screencast and used through this series. To process the messages (both XML and JSON), Aaron layers a data contract over the incoming message, to allow the .NET developer to work with the content in a strong typed, dot-notation fashion. After demonstrating how to hand-craft the .NET objects, Aaron demonstrates how to use the new 'Paste XML as Serializable Type' command to automatically generate the .NET classes from a sample Twitter XML response.

endpoint.tv Screencast - Declarative XAML Workflows in WF 3.5

Cliff Simpkins — Wed, 11 Mar 2009 15:00:00 GMT

Welcome to the latest video in the weekly WF/WCF Screencast series.

In this short video, CSD MVP Matt Milner from PluralSight guides the viewer through how to use declarative XAML workflows.

In this screencast, Matt demonstrates how to build and run your workflows in XAML; allowing you to express your workflow completely in this XML-based format. He starts off by creating a new WF workflow using the XAML workflow project file, and walks the viewer through the files that are created by this VS project, and how to remove the code behind (.cs file) so that your workflow project will be based soley on a XAML file to explain it. We then work with the workflow in both the XAML/text editor and the WF designer to add the business logic, modify the .NET application to read in and process the XAML file, and run the workflow.

Along the way, Matt then delves into the created XAML file to examine and explain the structure and used namespaces in that XAML file. Matt also explains the impact of starting XAML only workflows - how and why we need to load the XAML file differently, and some additional exception handling that you should add to handle the runtime exceptions that can come with XAML-only workflows (because the workflow isn't being compiled, the validation is happening at runtime).

endpoint.tv Screencast - Using the Listen Activity in WF 3.5

Cliff Simpkins — Wed, 04 Mar 2009 16:00:00 GMT

Welcome to the latest video in the weekly WF/WCF Screencast series.

In this short video, CSD MVP Matt Milner from PluralSight guides the viewer through how to use the listen activity in Windows Workflow Foundation (WF) to listen for multiple events.

Matt starts with a basic sequential workflow console project and a couple custom activities. He then builds out a workflow that waits for input from the user (using a read line activity), and also implements a timeout (using a delay activity) that allows the workflow author to place a limit around how long a WF workflow will wait for input.

Along the way, Matt explains the user how the use of IEvent activity interface allows custom activities to subscribe to events that the listen activity can pass along. Also covered is how to catch exceptions that may arise after using the delay activity to 'timeout' the WF workflow.

endpoint.tv Screencast - Fault Handling in WF

Cliff Simpkins — Wed, 25 Feb 2009 16:00:00 GMT

Welcome to the latest video in the weekly WF/WCF Screencast series.

In this short video, CSD MVP Matt Milner from PluralSight guides the viewer through how fault handling works in Windows Workflow Foundation (WF) 3.5.

In this screencast, Matt starts with an existing workflow application (a console application), and adds a custom activity that throws an exception. Initially, Matt demonstrates how this is thrown and it's effect on the workflow instance. He then demonstrates how to add fault handlers into a WF sequence to handle faults in a more graceful manner - very similar to the C# try/catch pattern. Matt also explains how exceptions 'bubble up' within a WF workflow - very similar to standard .NET applications.

endpoint.tv Screencast - Working with Transactions in WF

Cliff Simpkins — Wed, 04 Feb 2009 16:00:00 GMT

Welcome to the latest video in the weekly WF/WCF Screencast series.

In this short video, CSD MVP Matt Milner from PluralSight guides the viewer through how to work with Windows Workflow Foundation (WF) transactions, from the simple use case of scoping activities to participate in a transaction to the more advanced scenario of queue up work to participate in a transaction from an activity or the WF host application.

In this screencast, Matt demonstrates how to use the transaction scope WF activity and set the necessary properties on the activity. He then dives into how transactions work in WF to guarantee consistency in the activities, the WF workflow, and the overall transaction that WF is participating in. Along the way, Matt uses console outputs to demonstrate the execution order of activites and the transaction to visually demonstrate what the runtime is actually doing once you execute the code.

endpoint.tv Screencast - Using the WF Replicator Activity

Cliff Simpkins — Wed, 28 Jan 2009 16:00:00 GMT

Welcome to the latest video in the weekly WF/WCF Screencast series.

In this short video, CSD MVP Matt Milner from PluralSight guides the viewer through how to using the WF replicator activity to add more advanced flow control capabilities to your WF workflows.

In this screencast, Matt introduces the replicator activity, which allows you to implement ForEach-like semantics on workflow data. He adds the replicator to an existing workflow, binds the activity to the incoming data, and demonstrates how the replicator activity runs child activities. For this screencast, Matt uses an example sending e-mail notifications to persons in a data list.

While explaining how the replicator works, Matt explains a few aspects of the replicator activity: (a) how to interact with child activities within the replicators events, (b) how to set the activity execution type to have control over how the iterations are executed (i.e., sequence or parallel), and (c) how to use conditions to set a replicator stopping point.

endpoint.tv Screencast - Working with WF Tracking Profiles

Cliff Simpkins — Wed, 21 Jan 2009 16:00:00 GMT

Welcome to the latest video in the weekly WF/WCF Screencast series.

In this video, CSD MVP Matt Milner from PluralSight guides the viewer through how to work with WF tracking profiles (both SQL and custom tracking services). In last week's screencast, Matt introduced you to tracking services in WF 3.5. This week, Matt expands on tracking profiles, detailing out to create a profile via code and SDK sample apps, serialize the profile out for use in applications, and how to use the profiles within your workflow activities and workflows.

To build the profile, Matt demonstrates how to create a tracking profile two ways: by code and using Workflow Tracking Profile Designer from the WF SDK. To build the tracking profile via code, Matt introduces the concepts of workflow track points, workflow tracking locations, and how to use workflow tracking events to specify the details that you want to track. He also demonstrates how to detail which activity types you wish to track. Matt also opens up a serialized profile XML file and walks the viewer through how the profile is stored. For the Workflow Tracking Profile Designer, Matt demonstrates how the app generates the same CML file, but also how it allows you to commit the tracking profile to a SQL database.

Finally, Matt demonstrates how to use tracking in your activities and workflows to track data at runtime. He demonstrates how to send data into the tracking provider from WF activities, and how to use the Workflow Monitor SDK sample application to pull and visually display the tracked data.

VE Codeclip - Virtual Earth Positionsbestimmung

Jan Schenk — Wed, 21 Jan 2009 13:47:00 GMT

Als dritten und vorerst letzten Teil der Serie über Virtual Earth und die Windows Live Tools CTP gibt es noch eine nützliche Kleinigkeit, die ich euch nicht vorenthalten will:
Positionsbestimmung per Zentrum der ausgewählten Karte.

Wir integrieren eine Standard Virtual Earth Karte mit Hilfe der Windows Live Tools, überlassen dem User die freie Wahl des Kartenzentrums über die Standard-Navigation der Karte und setzen auf Button-Click einen Pushpin, oder Stecknadel, ins Kartenzentrum, dessen Eigenschaften wir so angepasst haben, dass als Beschreibung die aktuellen Koordinaten des Pushpins angezeigt werden.

Wie in den bisherigen Codeclips auch sind dafür nur wenige Zeilen Code notwendig.

Diese Vorgehensweise ist beispielsweise sinnvoll, wenn wir Datensätze mit Geodaten versehen wollen, die händisch hinzugefügt werden müssen, weil das Aufzeichnungsgerät (zB eine Digitalkamera oder ein Audiorecorder) die Daten nicht selbst mit Koordinaten versehen konnte.

So lässt sich im Nachhinein jeder beliebige Datensatz mit Koordinaten versehen.

Die Codesnippets findet ihr auf meinem msdn-Blog unter:
http://blogs.msdn.com/jansche/archive/2009/01/20/ve-codeclip-iii-virtual-earth-integration-und-positionsbestimmung.aspx

Bitte beachtet, dass ihr, falls ihr hier nur Copy und Pasten wollt, die Referenz auf Microsoft.Live.ServerControls.VE noch manuell einbinden müsst. Das passiert automatisch, wenn ihr das Map-Item aus der Toolbox in die ASP-Seite zieht.

VE Codeclip - Integration von Virtual Earth auf einer ASP.NET-Seite mit Windows Live Tools CTP

Jan Schenk — Thu, 15 Jan 2009 09:14:00 GMT

Einfacher geht es kaum. Wer schon immer eine Virtual Earth-Karte auf seiner Seite haben wollte und in ASP.NET entwickelt - das will ich schwer hoffen - sollte sich noch immer das November CTP der Windows Live Tools anschauen. Da ich dazu noch keinen deutschen Eintrag im Netz gefunden habe, kommt der Codeclip mit dem Beispiel der Integration gleich mit.

Kartensteuerung leicht gemacht. Mit einigen wenigen Klicks und den installierten Windows Live Tools hat man in Visual Studio 2008 eine Karte, ein Suchfeld, einen Submit-Button und ein paar Pushpins. Wer mehr will muss entweder selber ran, oder wartet einfach auf den nächsten Codeclip zum Thema. Der ist schon in Arbeit =) !

Die Windows Live Tools in der CTP vom November 08 findet ihr hier:
http://dev.live.com/tools/

Beachtet bitte, dass es sich hier immer noch um die Community Technology Preview (CTP) - Version handelt, und nicht in Produktiv-Umgebungen eingesetzt werden sollte!

Viel Spass!

endpoint.tv Screencast - Using SQL Tracking Services with WF

Cliff Simpkins — Wed, 14 Jan 2009 16:00:00 GMT

Welcome to the latest video in the weekly WF/WCF Screencast series.

In this short video, CSD MVP Matt Milner from PluralSight guides the viewer through how to add tracking capabilities to your WF using SQL Tracking Services.

In this screencast, Matt demonstrates how to add SQL Server workflow tracking services. He first sets up the SQL Server database/tables via Powershell, and how to add (and configure)the tracking service to the workflow runtime within the application. Once added, Matt demonstrates how to use the query API to print basic workflow information back out to a command-line Console.

As we add the service to the application, Matt also discusses the various persistance service settings that are available, such as data partitioning and profile configuration.

endpoint.tv Screencast - Creating Composite Activities

Cliff Simpkins — Wed, 26 Nov 2008 16:00:00 GMT

Welcome to the latest video in the weekly WF/WCF Screencast series.

In this short video, CSD MVP Matt Milner from PluralSight guides the viewer through how to create composite activities, combining multiple custom activities into a single custom activity that can be used in WF workflows. This screencast picks up where last week's Creating a Custom Activity screencast leaves off.

In this screencast, Matt demonstrates how to create a custom composite activity and add in two previously created activities. Once the composite activity is created, we then add properties to the composite activity, allowing the WF developer to set properties at design time on the WF designer.

endpoint.tv Screencast - Creating Custom Activities

Cliff Simpkins — Wed, 19 Nov 2008 16:00:00 GMT

Welcome to the latest video in the weekly WF/WCF Screencast series.

In this short video, CSD MVP Matt Milner from PluralSight guides the viewer through how to create a custom activity in Windows Workflow Foundation (WF) that can be used in WF workflows. To do this, we create a new class that inherits from Activity and has some properties. We then use this activity in a basic sequential workflow (for more information,).

Along the way, Matt explains the Execute method and some basics of the ActivityExecutionStatus.

endpoint.tv Screencast - Using the WCF to Consume Services in Windows Workflow Foundation (WF)

Cliff Simpkins — Wed, 12 Nov 2008 16:00:00 GMT

Welcome to the latest video in the weekly WF/WCF Screencast series.

In this short video, CSD MVP Matt Milner from PluralSight guides the viewer through how to use the WF 3.5 SendActivity to synchronously consume services using the Windows Communication Foundation (WCF) - it picks up from last week's screencast that introduced use of the ReceiveActivity.

To add a call to a remote service, we add a ReceiveActivity where there had been custom code and wire it to the proper service interfaces. Matt then uses ChannelTokens to use them to map the ReceiveActivity and SendActivity together.

Along the way, we use the Add Service Reference option to talk to the MEX endpoint (created last week), and create the configuration information from the WCF service endpoint. Matt also dives in deeper into the use of workflow activity events and properties.

endpoint.tv Screencast - Using the WCF Receive Activity in Windows Workflow Foundation (WF)

Cliff Simpkins — Wed, 05 Nov 2008 16:00:00 GMT

Welcome to the latest video in the weekly WF/WCF Screencast series. This week, we switch back to a series of WF screencasts.

In this short video, CSD MVP Matt Milner from PluralSight guides the viewer through how to use the ReceiveActivity within Windows Workflow Foundation (WF) to allow WCF clients to invoke the WF 3.5 workflow.

Matt starts with an existing WF sequential workflow (for more info, see Creating your First Sequential Workflow), and adds a WF 3.5 ReceiveActivity to the beginning of the workflow, and setup the activity to process the incoming work. To configure the activity, we add a service contract and a child activities to the ReceiveActivity that will process the request and return a result to the calling client and continue doing additional work after the workflow responds.

Along the way, Matt configures the workflow to create new instances of the workflow when a WCF call is received, and sets up the workflow in the WorkflowServiceHost that was added in 3.5. We will configure the host with an initial endpoint, add a MEX behavior, and then opens up the host. Matt then uses the WCF Test Client (discussed in Creating your First WCF Service) to interface with the hosted WCF workflow service to step through the workflow in the debugger.
