title: C# console application Streaming API 1.1 + Oauth
body: <p>I am using <a href="https://github.com/swhitley/TwitterStreamClient" rel="nofollow">swhitley's Twitter Stream Client</a> to download tweets via Twitter Streaming API with username and password. It was using <a href="https://stream.twitter.com/1.1/statuses/filter.json" rel="nofollow">https://stream.twitter.com/1.1/statuses/filter.json</a>.</p>
  
  <p>I modified the code to add OAuth, but I am getting a 400 error. Can anyone pls provide me code or direct me to an opensource project. Or just give me some tips on how to fix the issue.</p>
