Are you properly encoding your parameters? have you tried using POSTman plugin from Chrome, just to check things easily? – Erik

I ran into the same problem.

Make sure, that all your parameters are spelled correctly and that you URL-Encode the oauth_callback parameter: 

string requestUri = baseRequestTokenUri + "?oauth_callback=" + Uri.EscapeUriString(oAuthCallback);

Also make sure, that you use the correct signing key:

for ../request_token? this should be: {ConsumerSecret}+"&"+{RequestTokenSecret}
