Xml

I have an xml field (Answers) in Sql Server, but when changing the content via Linq-to-Sql, the record is not flagged for updating. e.g. in Linqpad...

var profile = Profiles.FirstOrDefault(p => p.Answers != null);
profile.Answers.SetAttributeValue("date", DateTime.Now.ToString());
GetChangeSet().Dump();                            // nothing flagged
profile.Answers = new XElement(profile.Answers);  // ends up with correct xml
GetChangeSet().Dump();                            // record is flagged as changed

Any suggestions apart from assigning a clone of itself to the field or storing the xml as a string to force the update?

In other words LINQ to SQL isn’t smart about many to many mappings… >>> More
