You must add a file called licenses.licx to your Visual Studio project that provides references to several namespaces. This is described in the RAB help files and elsewhere here in the forum.

Hi  
In VS just right click on the class library node and select add new item and then select text file and rename it to Licenses.licx and after that add the information to the file
