COM Interop Not Detecting .NET Functions Via Interface
I have a .NET assembly that I have executed regasm and gacutil. I also have a COM interop that I am trying to get to work with the .NET assembly. However, through my `pDotNetCOMPtr` I am not able to "detect" any of the methods on my .NET public interface. The MFC COM DLL keeps saying that there is not method called Encrypt in _SslTcpClientPtr. Thoughts?

    extern "C" __declspec(dllexport) BSTR __stdcall Encrypt(BSTR encryptString)
    {	
        CoInitialize(NULL);
    			
    	ICVTnsClient::_SslTcpClientPtr pDotNetCOMPtr;
    		
    	HRESULT hRes = pDotNetCOMPtr.CreateInstance(ICVTnsClient::CLSID_SslTcpClient);
    
    	if (hRes == S_OK)
    	{
    		BSTR str;
    	
    		hRes = pDotNetCOMPtr->Encrypt(encryptString, &str);		
    
    		if (str == NULL) {
    			return SysAllocString(L"EEncryptionError");
    		}
    		else return str;	
    	}
    
    	pDotNetCOMPtr = NULL;
    
        return SysAllocString(L"EDLLError");
    
    	CoUninitialize ();
    }
