Handling Concurrency with the Entity Framework in an ASP.NET Web Application

This tutorial shows options for handling concurrency in an ASP.NET web application that uses the Entity Framework. You will create a new web page that's dedicated to updating instructor office assignments. You'll handle concurrency issues in that page and in the Departments page that you created earlier.

A concurrency conflict occurs when one user edits a record and another user edits the same record before the first user's change is written to the database. If you don't set up the Entity Framework to detect such conflicts, whoever updates the database last overwrites the other user's changes. In many applications, this risk is acceptable, and you don't have to configure the application to handle possible concurrency conflicts.
