Does specifying the OutAttribute on ByRef internal methods currently do anything?

Question

VB.NET doesn\'t have out parameters, but you can specify ByRef on COM and P/Invoke methods to get the same effect for external method

Answer 1

I subclassed MembershipProvider with a VB class, we'll call it A, and then subclassed A with a C# class we'll call B. The C# code, B, was not recognizing the fact that the abstract methods in the MembershipProvider had already been implemented in the VB subclass, A, until I applied the OutAttribute in the VB class for parameters that were specified as out in the MembershipProvider base class abstract methods. This has an impact beyond just COM or P/Invoke.
