Re: Asynchronous webservice call results in InvalidOperationExcept
The XML is in the correct format. Moreover it is the same XML that I get on
the Compact framework without any exception.
Here is the Stack Trace:
There is an error in XML document (5, 495). ---> System.Xml.XmlException:
Unexpected end of file has occurred. The following elements are not closed:
result, ns1:getUpdateResponse, soapenv:Body, soapenv:Envelope. Line 5,
position 495.

Consider how unlikely it is that you are correct that there is no problem
with the XML, but that .NET is incorrect.
How did you determine that it's the same XML? How did .NET determine that
it's bad XML? Consider the difference between the two and ask yourself: how
can we both be right?

Hint: "Unexpected end of file has occurred". While you are asynchronously
handling your response, .NET is reading and deserializing the response
bytes. At some point, the XmlReader that is processing the data gets an EOF
from the underlying stream. It determines that you still have unclosed
elements, and throws an exception.
So the questions become, why does it think it's receiving the EOF, and why
do you think that it is not receiving an EOF?
