Migration from the old (v3.0). NET SDK to the latest version (v5.0)

Question

I originally used .net sdk for facebook, which can be found here:

http://facebooktoolkit.codeplex.com/

but now I'm trying to upgrade to the latest version, which is posted below, and implements many of the new facebook features that were recently:

Despite the fact that I created several applications for facebook canvas and even integrated our company’s website in order to use facebook connection, I still got a little confused about the nuances and details about facebook authentication / authorization changes. For example, how can I transfer the .NET .NET server code below, which I used from our old (v3.0) .NET SDK integration with Facebook, to the new v5.0.NET SDK?

            string perm = "publish_stream"; //or any permission you want to check
            FBConnectAuthentication auth = new FBConnectAuthentication(Settings.FBConnectAPIKey, Settings.FBConnectAPISecret);
            FBConnectSession fbSession = auth.GetSession();
            string userId = fbSession.UserID;
            var session = new Facebook.Session.ConnectSession(Settings.FBConnectAPIKey, Settings.FBConnectAPISecret);
            var api = new Facebook.Rest.Api(session);
            var usr = SessionInfo.CurrentUserOrUserAccountWithLastEmailAddressEntered;
            Facebook.Schema.Enums.ExtendedPermissions perm
                = (Facebook.Schema.Enums.ExtendedPermissions)Enum.Parse(typeof(Facebook.Schema.Enums.ExtendedPermissions), permission);
            hasPermission = api.Users.HasAppPermission(perm);

REST apis, sdk OAuth access_token?

FB.Connect.showPermissionDialog('publish_stream, email, user_checkins', publishToWallPermissionGranted);
