I am using entity framework 4.1.What is the best way to handle concurrency with entity framework. Is there inbuilt functionality to handle it in entity framework? Can I do without adding extra column to the tables to keep row version?

Have you seen this tutorial: http://www.asp.net/entity-framework/tutorials/handling-concurrency-with-the-entity-framework-in-an-asp-net-mvc-application
您可以在没有rowversion列的情况下执行，但是通常需要存储大量状态，这会对性能产生不利影响。
You can do it without a rowversion column but that often requires storing a lot of state, which can adversely affect performance.
