The following code:


should return


but instead causes an exception:

    System.NotSupportedException: Operation is not supported.

Cursory analysis, the problem is that the IntrospectionExtensions.GetTypeInfo() extension method returns a TypeDelegator instance, which inherits TypeInfo, which inherits Type.

The problem seems to be that TypeDelegator doesn't override and delegate Type.GetGenericArguments(), resulting in the default Type.GetGenericArguments() behavior which throws NotSupportedException.
