Exception: System.InvalidOperationException: Response is not well-formed XML. ---> System.Xml.XmlException: Data at the root level is invalid. Line 1, position 1

So whatever you send to C# is not valid ("well-formed") XML. The problem is found at the first character in the first line, at the root element. See XML and Well-formed document.
