Access my C# dll in C++

[capitolc]

here's my C# dll:

public interface IMessage
{
     void Testing();
}

public class MyTest : IMessage
{
     public void Testing()
     {
          Console.WriteLine("Testing dll");
     }
}

here's my cpp code:

#import "....\aName.tlb" raw_interfaces_only

using namespace aName; 

int _tmain(int argc, _TCHAR* argv[])
{		
	// Initialize COM.
	HRESULT hr = CoInitialize(NULL);

	// Create the interface pointer.
	IMessage pIMessage(__uuidof(MyTest));
	
	// Uninitialize COM.
	CoUninitialize();

	return 0;
}

..and here's my error:

I created my dll, created a MyKeyFile, and I used the command to run regasm creating my .tlb file. All that seems fine. The C++ code I used came from a quick example on a microsoft support page. My issue is the error saying I have an astract class when I didn't declare an astract class. Maybe it has something to do with those methods that seems to be coming from HRESULT. I don't know if I'm making a mistake with the C++ code accessing the dll, or if I made a mistake within my dll. I just want to access a method in the dll. Any thoughts?
