Consider this scenario:

1. You have expansion-deps.projitems which contains the @(JdkIncludePath) item group.
2. You have expansion.props which uses @(JdkIncludePath) to generate a $(_JdkIncludePaths) property
3. You have expansion.projitems which creates a new @(_HostRuntime) item group which uses $(JdkIncludePath) within the %(_HostRuntime.CFlags) item metadata
4. You print out %(_HostRuntime.CFlags).

Incredibly, behavior differs between xbuild, msbuild in mono 4.6, and msbuild in mono 4.8.

Binding Java 8 Interfaces from C♯

Help wanted! :-)

Background

Xamarin.Android binds the Android Java API, which means that all Java language features need to be "bound" to corresponding C# language features. For many language constructs, this binding is simple, e.g. type names are (usually) unchanged and identical, while other language features are changed in subtle
