Does EF5 DbContext.SaveChanges handle transaction commit and rollback?

Question

I am not clear on whether I need to use TransactionScope or DbContext.SaveChanges() is enough to commit my transaction consisting of multiple CRUD operations. I am using SQL Server in the backend.

Answer 1

If you are calling SaveChanges() multiple times, and want to roll back all of those changes, yes you would want to use a TransactionScope. If you are calling SaveChanges() once on the context, all your changes are pushed to the database at once in a transaction behind the scenes.
