SAP .net connector and Visual C++ 2010?

Greetings,

I'm developing an application in visual C++ using visual studio 2010 and I'm using the following guide to try and get SAP .net connectivity to work:

http://www.codeproject.com/KB/dotnet/SAP_NET_Connector.aspx

I'm having problems from the get-go, however, as "SAP connector proxy" does not appear under Project->Add->New Item.

Looking around google, I have a sneaking suspicion that the problem might simply be that Visual Studio 2010 is no supported, despite it using the .NET 4.0 framework. Is this indeed the problem? Would I be better to roll back to Visual Studio 2008? Or am I missing some bigger point?

thanks in advance for any help!
