As I posted in my previous post, i have an inheritance chain of A : B : C
I have 2 extension methods that cover this A, and this C.
If I invoke the extension method for this C from a typeof(B) it will display this error. Once again it seems to do with inheritance chains not being evalulated at all, let alone just the first ancestor.
