An extra cast is required from IFoo<T> to IFoo where IFoo<T> is IFoo.

public interface IFoo { }
public interface IFoo<T> : IFoo { }
public class Test
{
        public IFoo GetFoo () { return GetFooGeneric<object> (); }

        public IFoo<T> GetFooGeneric<T> () { return default (IFoo<T>); }
}


Actual Results:

cast.cs(5,26): error CS0266: Cannot implicitly convert type
`IFoo<System.Object>
' to `IFoo'. An explicit conversion exists (are you missing a cast?)

Expected Results:

no CS0266 error

How often does this happen? 

consistently.

Should be easy; now looking at it.

Ok, it's a runtime issue and more difficult than I expected :-(
Still working on it.

Actually this bug is not so important; we could add explicit cast
until it is fixed.

This one was really difficult to figure out, but in the end it had a
very simple fix - which is now in SVN :-)
