…ixes xamarin#15708 Allow code like this ```csharp [DllImport(Constants.ObjectiveCLibrary, EntryPoint = "objc_msgSendSuper") static extern IntPtr IntPtr_objc_msgSendSuper(IntPtr receiver, IntPtr selector); [DllImport(Constants.ObjectiveCLibrary, EntryPoint = "objc_msgSendSuper")] static extern void void_objc_msgSendSuper(IntPtr receiver, IntPtr selector, IntPtr arg); [Export("selectedTextRange")] public new IntPtr SelectedTextRange { get { return IntPtr_objc_msgSendSuper(SuperHandle, Selector.GetHandle("selectedTextRange")); } set => void_objc_msgSendSuper(SuperHandle, Selector.GetHandle("setSelectedTextRange:"), value); } ``` to work on the dynamic registrar since it already work with the static one. This allows the simulators (which defaults to dynamic) to share the same code which is useful for implementing a workaround for related issue xamarin#15677.

Since you have the fullname, why not change the assertion message to:
xamarin_assertion_message ("Don't know how to marshal a return value of type '%s', Please Please file a bug with a test case at https://github.com/xamarin/xamarin-macios/issues/new\n", full name);
On a side note, I wonder if this won't be immediately stale with the .NET 6 transition to NativeHandle instead of IntPtr.

Both good points @stephen-hawley I'll address them shortly. Thanks!

There are two functions that are much faster and simpler: xamarin_is_class_intptr and xamarin_is_class_nativehandle, no need to compute a full type name nor compare strings.

last little bit - since fullname is only used in the error and @rolfbjarne implies that it's more costly than the xamarin_is_class_ tests, how about moving the allocation and deallocation into the else clause so that the price only gets paid in the failing case.

I reverted the assertion to the original code as it did not need (extra) allocation, inside the caller, and still produced the same output.
