Two points: 1) We should probably have a clearer error message in this case. 2) That seems to be a bug since the behavior is different if IRubyEngine declares non-generic methods.
Please file a bug on CP with both points.

So let's say an interface contains the following method definition public interface IRubyEngine { T CreateInstance<T>(RubyClass rubyClass); } in ruby class MyEngine include IRubyEngine end So far so good nothing has actually been created yet.
