Problem Hiding Generic Implementation from Type Library Exporter

[Tom Z.]

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
}

[ComVisibleAttri bute(false)]
public class Container<T>
{
// imagine some stuff here
}

[ComDefaultInter faceAttribute(t ypeof(IContaine r))]
[ClassInterface( ClassInterfaceT ype.None)]
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( ClassInterfaceT ype.None)].
Class interfaces cannot be exposed for such types. Consider marking the type
with [ClassInterface( ClassInterfaceT ype.None)] and exposing an explicit
interface as the default interface to COM using the ComDefaultInter face
attribute."

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