I don't think the patch is correct. It is assuming that every "Add" method of a collection/list is compatible with AddDelegate(object). If the test cases are still working, it could be that CreateDelegate is buggy: MSDN states: "A parameter of a delegate is compatible with the corresponding parameter of a method if the type of the delegate parameter is more restrictive than the type of the method parameter, because this guarantees that an argument passed to the delegate can be passed safely to the method."
