Does anyway of a same of C# code they could share using the rest API. I am trying to login and access the candidate entity. I an new the rest api, used mostly soap api and I am just not connecting the dots right now. I think I was successfully in get an access token but I get an "Invalid or expired OAuth access token" error when I try to login with it, so I am not sure that's right.
If some one could be share an sample of how they are using rest api to login and to access any entity in C# it would be awesome.
