Go into your DbContext implementation and override SaveChanges.

In there, if you call the base.SaveChanges() method FIRST then you can do whatever you want. DO NOT CHANGE MORE STUFF IN THE DATABASE AND CALL SaveChanges FROM INSIDE YOUR SaveChanges METHOD OR YOU WILL END UP IN AN INFINITE LOOP UNTIL YOU CRASH THE APP BY EXHAUSTING THE STACK SPACE OF YOUR APP.

Now, if you make the additional changes BEFORE you call the base.SaveChanges() method, this won't be a problem.
