I\'m creating an app with MVC4 that will authorize users using Twitter and lets them tweet from the app as well. I\'m able to get the user authenticated without a problem us
You can extract the oauth_token_secret from OAuthWebSecurity by designing your own TokenManager. You can register the token manager when you register your Twitter client in OAuthWebSecurity.RegisterClient.
I used this method to extract the needed values to be able to bypass the authorization step of the Linq-to-Twitter lib.
I will soon post my solution at my blog.
