When a Microsoft .NET Framework 2.0-based application calls the HttpListenerRequest.InputStream.EndRead method to wait for a pending asynchronous read to finish, the HttpListenerRequest.InputStream.EndRead method does not return the actual number of bytes that are read from the stream. Instead, the HttpListenerRequest.InputStream.EndRead returned the incorrect number of bytes that have been read.
