I've been able to create a successful web request to receive an auth token from Twitter. However, Twitter is not sending me back to my development environment even though I have put the oauth_callback parameter on my request. It even shows my call back parameter in the URL on the Twitter oAuth authentication page.
I'm wondering if anyone else is using VS 08 (ASP .NET) as their development environment and were able to successfully get the oAuth call back parameter to redirect back to their development environment? -Matt
