Is it possible to inherit from EntitySet?

I just tried creating AddressSet : EntitySet

... after adding some entities to the set, calling Addresses.ElementAt(0) throws an exception.

If I change the type of the property from AddressSet to EntitySet

, there is no exception.

Hello,

Yes, EntitySet<t> class is intentionally inheritable. Thanks for the bug report, we'll check the issue asap.

Definitely a bug.

P.S. Providing the stack trace might help a lot in such cases.

Hello. I tried to repeat this error, but everything works OK for me. Could you help me a little bit? To repeat the bug I need: 1. Your model. 2. Code of AddressSet class 3. Code there you add entities to AddressSet and call ElementAt method. 4. Exception message and stack trace.

Thank you.
