Windows Assembly Runtime

how to find out if an AssemblyReference is Windows Runtime Assembly?

[Washi1337]

There is no direct property for it (yet). You can resolve the assembly reference to a definition, and then compare the VersionString property in the underlying metadata header. For WinMD assemblies, it should contain start with the string WindowsRuntime, followed by the version number.

Actually, it can be done without resolving the assembly. It is encoded in the assembly attributes with a that AsmResolver 3 does not define yet.

bool isWindowsRuntime = (assembly.Attributes & 0x0E00) == 0x200;

Note that v4 does indeed define these constants.
