PCo Agent SDK - The type or namespace name 'SAP' could not be found

Hi everyone

I am trying to create a new PCo custom agent, using the PCo Agent SDK's wizard. I've followed the steps given in this (excellent) document:

http://scn.sap.com/docs/DOC-32671

However, when building the agent in Visual Studio 2012, I get compiler errors:

The type or namespace name 'SAP' could not be found (are you missing a using directive or an assembly reference?)

I've checked the references. SAPs Connectivity.Framework is referenced in my solution. I've also checked this document, but don't seem to be getting anywhere..

What am I missing?

Thanks & regards

Jan
