IDbAsyncEnumerable not implemented

Question

I am trying to make a FakeDbContext with a FakeDbSet for unit testing.

But I get the following error (see below). I am extending DbSet so normally IDbAsyncEnumerable

Answer 1

DbSet probably implements IDbSet implicitly so that those methods are not available for interface mapping in your derived class.

Don't derive from IDbSet.

You cannot call the explicitly implemented interface members of IDbSet from a re-implementation of that interface.
