Description Edward Brey 2017-04-25 16:38:06 UTC
When XamlCompilation is enabled, the build output warns of a conflict between the MonoAndroid and .NET versions of mscorlib.

Environment:
* VS2017
* Xamarain.Android SDK 7.2.0.7
* JDK: 1.8.0_112 (latest installed via VS2017)
* Android NDK: r13b (latest installed via VS2017)
* Android SDK: 7.1 (latest installed via Android Studio)

Repro:

1. Create new project: Blank App (Android)

2. Install-Package Xamarin.Forms -DependencyVersion Highest

3. Add this line to MainActivity.cs before the namespace:
[assembly: Xamarin.Forms.Xaml.XamlCompilation(Xamarin.Forms.Xaml.XamlCompilationOptions.Compile)]

4. Build

Results:

This warning appears:
No way to resolve conflict between "mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" and "mscorlib, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e". Choosing "mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" arbitrarily.

Forgot a repro step:
3.1. Add a new "Forms Blank Content Page Xaml" item to the project.
