Unblock ExecuteUpdate column-self-reference EF Core tests: not a simulator gap — ExecuteUpdate bypasses the change tracker, but the verification queries used context.Users.Single(...) which returns the tracked entity (cached from the initial AddRange/SaveChanges) with the stale pre-update value. Changed verifications to AsNoTracking().Single() so the identity-map shortcut doesn't surface stale data. The literal-value sibling test masked the same pattern by verifying via .Sum(), which is an aggregate query that always hits the DB. Probe-confirmed the simulator's UPDATE [u] SET [u].[col] = [u].[col] + 1 FROM [Users] AS [u] WHERE … path was already correct — EF's exact emitted SQL works end-to-end through a raw connection.
