UpdateFromQuery fails using related entity with inheritance (EF and EF Core)

[davidnemeti]

Description

UpdateFromQuery fails when using related entity if the updated entity is of a derived entity type.

Note that if inheritance is not involved, then it succeeds in EF, but still fails in EF Core.

Hello @davidnemeti ,

Unfortunately, that's currently unsupported.

However, we are currently working hard to recode some parts of our library to be able to handle more complex scenarios like this one. I cannot provide any expected date but I believe it will come during this summer.

Best Regards,

Jon
