EntitySet<TEntity>.Ensure Method

Ensures that the entity with a specified EntityIdentifier is not removed or replaced with a different entity with the same identifier before a transaction is committed. If another transaction commits first and removes or replaces the entity, the transaction will raise a TransactionConflictException when it is committed. It is valid to call this method with an id that is not present in the entity set. In that case, a TransactionConflictException will be thrown if an entity with id is added to the entity set in another transaction.
