How can I parse/deserialize a MTOM/XOP response that I get from a web service using WCF? I have the response on disk. I have copied the response below:

Any help is much appreciated.
You can deserialize the response using the WCF classes, as I'll show below. But before we proceed, this MTOM is invalid - the parameter boundary of the Content-Type header is malformed. Since it contains the '?' character, it needs to be quoted (look at the MIME RFC, section 5.1, definition of token).
Now, to deserialize it, you need to open the document with a MTOM reader - and XmlDictionaryReader.CreateMtomReader will give you exactly that. With that reader created, you can pass it to the DataContractSerializer to deserialize the object. The code below shows how this can be done.
