I've just updated my WP8 app to use the latest MixRadio 3.3 package through NuGet. Seems like the new MixRadio library version added the dependency to Microsoft.Bcl.Compression, which does not work if the WP8 app is set to AnyCPU. The need to compile platform-specifically when using that library is also documented here: http://blogs.msdn.com/b/dotnet/archi...ow-stable.aspx
Is that dependency really required? I'd prefer to stay with AnyCPU as there is no need for architecture specific compilation in the rest of the app, and the MixRadio integration is just a small feature within the overall app.
