EDIT: Issue is fixed in MVVMCROSS v3.2.1 !
With the current NuGet version of MvvmCross, when adding it to the project you get duplicate folders (‘Layout’ and ‘layout’, ‘Values’ and ‘values’)
To fix this, right click on the project and choose ‘Tools \ Edit File’ in Xamarin Studio. In Visual Studio, there’s a similar way.
In the .csproj, you just need to replace the first upper case letter with lower case letter, so replace ‘Layout’ with ‘layout’ and ’Values’ with ‘values’ and save the file.
