Problem Hiding Generic Implementation from Type Library Exporter

P: n/a
Hi All,

I'm trying to make an assembly in C# to use as a COM server. I'm building as
normal and ruinning regasm at the end. Everything is generally working,
except that I'm having a problem hiding some generic implementation base
classes from the type library exporter.

Here is a code sample:


public interface IContainer
// imagine some stuff here

public class Container<T>
// imagine some stuff here

public class Test : Container<int>, IContainer


This code compiles properly, but regasm gives this warning:

"Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as [ClassInterface(ClassInterfaceType.None)].
Class interfaces cannot be exposed for such types. Consider marking the type
with [ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the ComDefaultInterface

The class is skipped and not exported. What am I doing wrong here?
