I am trying to configure  Microsoft SAP Adapter 2.0.

I created send and receive ports as for documentation, RFC programs
also running at receive location folder,when i started buldingIdoc XSD
from SAP Adapter Wizard i am getting error:

FileNotFoundException: File or assembly name SAP.Connector,or one of
its dependencies, was not found

I have to generate Idoc XSD from SAP Adapter.

The Microsoft SAP Adapter V2 works with the SAP .NET Connector V1.0.3.

If you have V2 of the .NET Connector then you get the error you have seen. Try removing the V2 .NET connector and replacing with 1.0.3.The results you get seem to vary with the installations that have beeninstalled. Some folks report success with the .NET Connector V2
