How to override the SaveChangesAsync of any DbContext globaly?

Question

I want to override the

public virtual Task<int> SaveChangesAsync(CancellationToken cancellationToken = default);

of any DbContext in my solution globaly and change it to

public virtual Task<MyDatabaseReturnModel> SaveChangesAsync(CancellationToken cancellationToken = default);

Is that possible?

Answer 1

Is that possible?

No. You can't change the signature of a method by overriding it. You can only change the implementation . The SaveChangesAsync method must still return a Task<int> or int . This is how it is defined.
