I have not worked with .net & sql server. I used to setup for customers vs web services calls through oauth2. We need to setup server with database data to access by client.

Please go through this link,  It has clear documents to implement oauth2 server.

Hi Loganathan Natarajan,

      Thanks for your reply,  I need one clarification, does the keys and webservices server reside on the same server to serve customers?   or in different servers.  Do we need to store keys and secret in database? Please revert back to me.

With Many Thanks,
Bharath AK
