I'm also puzzled, because I use a TCP binding out of the "WCF box" (we use WPF). Why an XML encoding problem? I have been unsure if actually binary encoded is used.
Therefore, I looked at the stack a bit in a debugger, and although im not a WCF expert, I got to the conculsion that some validation is made on XML base, either before or after the actual encoding (that I guessed from method names on the stack indicating something like "validate").
The encoder property of some WCF class was set to BinaryFormatter, which is what I really wanted to be sure.
I could the "first chance exception" narrowed to the already mentioned auto property in our classes and ObservableBindingList (AllowEdit, AllowNew, AllowRemove). So, I stick with the "old style" properties with an explicit internal field. That reduces the chatty messages in VisualStudio's Output. a lot.
