XmlSerializer and circular reference

The XmlSerializer can't cope directly with circular references though, if you can identify which property is causing the problem, you might be able to get around it using a combination of the XmlIgnore attribute and the IXmlSerializable interface.

If that can't be made to work then you could try using the DataContractSerializer instead.

I'm very short on time just now but perhaps I could refer you to this thread for some ideas on the matter:
