@Maria: I don't know if you realize this but there is a more recent version of this course available at Microsoft Virtual Academy. I don't have the URL but you can easily find it by searching online or go directly to their site. It's mostly the same content but there are some improvements here and there. Just thought you'd want to know. Thanks for the nice words.
@Sagar: I'm really sorry to tell you this ... four years ago and several versions of Windows 8 have come and gone. This course is essentially dead. As you see, the previous question before yours was asked in June 2014. That was literally a lifetime ago when it comes to mobile development on the Windows phone platform. I'm very sorry ... this is the nature of technology. I would recommend you take a look at the UWP course I created in 2015, although now that is two years and one generation behind.
@Protoss_Ricky: Great, glad you're able to understand the videos.
@Andre Moreira: Hmm... I'm not sure you can transpile across the two APIs. I'm willing to bet you could (a) remove all the non-presentation logic into it's own package and share it across two projects (DLL), and then (b) copy and paste *most* of the XAML and code behind into a second project.
There might be an easier way, but I'm not familiar with that process.
@zur: When you say "Visual Studio is complaining" ... Yes, Visual Studio will complain. While that API has been deprecated, at the time of this recording there was no replacement that I was aware of. The key is: does it COMPILE and run? (It should ... that's my exact code).
@Hemanzt: Could you be more specific? I'll help if I can.
@Hemanzt: I assume that you are running the completed version of this project, correct? If so, you will need to restore the NuGet packages. Right-click on the Solution in the Solution Explorer, select "Restore NuGet Packages".
As far as songs go ... it will look at your own library of songs! If you don't have any music, I believe you can download the ones I'm using (just copy them into your Music folder in Windows 10).
