Explain the implementation and performance of ExecuteUpdate and ExecuteDelete (EF Core 7+).

They execute a single SQL command immediately against the database without tracking or pulling entities into memory.

Because it bypasses the ChangeTracker, it avoids memory allocation and massive network traffic. ExecuteUpdate generates a clean UPDATE table SET ... WHERE ... statement. ExecuteDelete generates a DELETE FROM table WHERE .... The performance is identical to raw ADO.NET or Dapper.
