I have thit "while" loop and it constantly reads a Json stream. But when the connection is lost there is no way to get out of the "while" loop. It remains stuck in the "reader.Read()" line, waiting for next Json token, which will never arriver because the connection is lost. So no code in the while loop will be executed. Can somebody help me please? Thank you.
