            using (Stream newStream = request.GetRequestStream())
            {
                newStream.Write(SomeBytes, 0, SomeBytes.Length);

        return request;
    }

Answer 1

using (Stream newStream = request.GetRequestStream())
{
    newStream.Write(SomeBytes, 0, SomeBytes.Length);

    //try to add
    newStream.Close();
}
