+Summary: [GMCS] differentiate generic arguments on method return types
+
+gmcs cannot differentiate such methods that have the same args, same type
+body name, but have diffrent generic arguments on the return type.
+
+--------
+public interface Ret {}
+public interface Ret<T> {}
+
+public abstract class BaseClass
+{
+        public virtual Ret Foo () { return null; }
+        public virtual Ret<T> Foo<T> () { return null; }
+}
+
+public class DerivedClass : BaseClass
+{
+        public override Ret Foo () { return null; }
+        public override Ret<T> Foo<T> () { return null; }
+}
+
+
+Actual Results:
+
+overload-override.cs(12,22): error CS0508: `DerivedClass.Foo()': return
+type must be `Ret<T>' to match overridden member `BaseClass.Foo()'
+overload-override.cs(7,26):: `BaseClass.Foo()', name of symbol related to
+previous error
+Compilation failed: 1 error(s), 0 warnings
+
+Expected Results:
+
+no error (except for entrypoint not found).
+
+How often does this happen? 
+
+consistently.
