public class Bugged
static void CB (IAsyncResult res)
public static void Main ()
var wr = HttpWebRequest.Create ("http://google.com");
wr.Method = "POST";
var stream = wr.GetRequestStream ();
//str.WriteByte (0xAC); // Uncomment this to make it work
var gr = wr.BeginGetResponse (CB, null);
I did quite some digging when fixing other bug and the issue is most likely in how
void CheckIfForceWrite ()
works. It seems to assume that when the stream was requested it will always be filled.
