----------------------------------------------------------- From: Varad_RS Message 22 in Discussion #) Important Note: Breaking changes when using COM Interop Keep in mind that when you add methods to an assembly you must retain the same order within the code file (and resulting MSIL code within the compiled assembly) otherwise the interface sequence will change and you will break compatibility. If you always add new code to the end of a code file you'll never see this but if you add COM visible methods between existing interface methods you'll change the order of the interface because regasm creates and registers the interface in the order that the methods appear within the physical assembly. #) What exactly is the effect of declaring a methods as "virtual new"? The new modifier applied to a virtual function allows you to explicitly hide a member inherited from a base class hence the �virtual final� in the IL. >From the docs: "To hide an inherited member, declare it in the derived class using the same name, and modify it with the new modifier." A class-member-declaration is permitted to declare a member with the same name or signature as an inherited member. When this occurs, the derived class member is said to hide the base class member. Hiding an inherited member is not considered an error, but it does cause the compiler to issue a warning. To suppress the warning, the declaration of the derived class member can include a new modifier to indicate that the derived member is intended to hide the base member.
