Please see "Steps to reproduce".

Note that the program works fine when no serialization dll is generated. And the program works fine when the declaration of StringList is moved before the declaration of MyStringCollection (because this changes the types contained in the serialization dll).

What I especially dislike with this issue is that the failure is completely silent - no errors, no exceptions.

Hi Martin,
Thanks for your feedback. Since there is a workaround available right now, we have decided not to fix this in the current release. We will continue to monitor the customer feedback and reevaluate if more customers run into this.

Well, maybe the MSDN should contain some more documentation where to find the settings files ;-)

C:\Users\<your user>\AppData\Local\<Company>\...
