XPQuery changes regarding non-persistent properties in v17.1

In version 17.1, we have improved error detection in XPQuery when non-persistent properties are used in it. Previously, such queries didn't work (either failed with various exceptions or worked incorrectly) and thus there were hidden errors in your programs. Now, we throw an exception that describes which non-persistent properties are used in XPQuery to help diagnosing these errors. If such properties are used intentionally, consider implementing them using PersistentAliasAttribute or adding the ToList method call to explicitly process these properties on the client side.

Refer to the KB Article for examples and more details.
