[twitter-dev] rate_limit_status called from .NET WebClient class

[J.D.]

I must be doing something wrong. If I call rate_limit_status with
CURL, I can see 2 different counts, depending on if I pass my
credentials or not. If I do the same thing from a .NET application, I
always get the non-authenticated (IP address limit) results.

I know setting the WebClient credentials this way works, as I call
other twitter API's after authenticating, plus I can call
verify_credentials this way and it works.

Can anyone see what I'm missing or screwing up?

      public void TestLimitInfo()
      {
         WebClient wc = new WebClient();
         wc.Credentials = new NetworkCredential( "myuser", "mypass" );

         string data = wc.DownloadString( "http://twitter.com/account/
rate_limit_status.json" );
         MessageBox.Show( data );

      }  // GetLimitInfo

TIA,
J.D.
