Sharing is caring! I got some super awesome help from Daniel Plaisted again , again related to Portable Class Libraries, and more particluar the Async for .NET Framework 4, Silverlight 4 and 5, and Windows Phone 7.5 1.0.12-beta. After installing it in a PCL, adding a project and attempting to add other packages the app failed to start. Giving me an error message that didnt help much:
Unable to activate Windows Store app ‘db427b9e-06d0-491f-b8e7-fa5450a5dabd_snjqad683v1dc!App’.
The App1.exe process started, but the activation request failed with error ‘The app didn’t start’.
Great. That helps, NOT!
This is why:
NuGet will try to add an app.config with binding redirects to Windows Store apps if it thinks it is needed. However, Windows Store apps don’t need app.config, and will actually fail to start with a very confusing error message if it is present.
Remove the App.config
