2. Removed "netcoreapp1.0" from project.json as it is not required. 3. Updated generated OPC type classes with latest definitions. 4. Added session-less request validation. 5.Added small helper method in certificate store ID class. 6. Added OAuth2 credentials. 7. Brought original user identities back in (username, cert, certIDs) and added JWTs.
