Debugger issue

While debugging and stopped at a breakpoint, the example below shows that method does not exist, while it's declared as extension method:

var str = new NSAttributedString ("My Text Here");
nfloat size = str.GetSize().Height;

Hovering over Height will show you that no method exists, while GetSize() is correctly evaluated with the Editor resolver (not the debugger one)

Right now we only support LINQ extension methods because supporting other extension methods is tricky.
