Fetching List of SAP CRM data like opportunities, Contact, Account etc in the .Net 4.0

Hi All,

I am developing and application in .Net 4.0, which will find list of accounts/contact based on the given email address.

Also I need to find our created opportunities in the SAP CRM based on the email address and search criteria.

I have read about the .Net Connector 3.0 and tried to connect the SAP server, I am successfully connect to SAP server but then after I am stuck with which BAPI/RFC function should i use to fetch such data? and in which format SAP will send the data and how to parse it to the .Net objects?

I would be very thankful if someone gives sample code in .Net to fetch the list of opportunities, Contact, Account from SAP CRM?

Thanks

Saumya
