Hi

Based on my understanding, you wants to expose the .NET class to the COM
interface, if I have any misunderstanding, please feel free to let me know.
In MC++, we can do the job below to expose the IMyInterface to the COM
client, after built we need to use the regasm to generate the tlb file for
com client to use.

using namespace System;
using namespace System::Windows::Forms;
using namespace System::Runtime::InteropServices;
namespace MCPP
{
        [InterfaceTypeAttribute(ComInterfaceType::InterfaceIsDual)]
        public __gc __interface IMyInterface
        {
                void HelloWorld();
        };
        [ClassInterface(ClassInterfaceType::None)]
        public __gc class MyClass : public IMyInterface
        {
        public:
                void HelloWorld()
                {
                        Form* fm = new Form();
                        fm->Show();
                }
        };
}

Although the MC++ IDE did not did all the job as C# do, but we still can do
the similar job with C#.
