New Post: How do I add authentication to a WFA?

``` private void button2_Click(object sender, EventArgs e)

    {

        var applicationCredentials = CredentialsCreator.GenerateApplicationCredentials(consumerKey, consumerSecret);
        var url = CredentialsCreator.GetAuthorizationURLForCallback(applicationCredentials, "https://tweetinvi.codeplex.com");
        Console.WriteLine("Go on : {0}", url);
        Console.WriteLine("When redirected to your website copy and paste the URL: ");

        // Enter a value like: https://tweeetinvi.codeplex.com?oauth_token={tokenValue}&oauth_verifier={verifierValue}

        var callbackURL = Console.ReadLine();

        // Here we provide the entire URL where the user has been redirected
        var newCredentials = CredentialsCreator.GetCredentialsFromCallbackURL(callbackURL, applicationCredentials);
        Console.WriteLine("Access Token = {0}", newCredentials.AccessToken);
        Console.WriteLine("Access Token Secret = {0}", newCredentials.AccessTokenSecret);

        return newCredentials;
    }
