You implement a method that uses Entity Framework to perform several update operations. You need to ensure that the method executes within the scope of an ambient transaction if an ambient transaction exists. If an ambient transaction does not exist, you need to ensure that the method's update operations execute as a single transaction.

What should you do?

If the scope is instantiated with Required and an ambient transaction is present, the scope joins that transaction. If an ambient transaction is not present, a new transaction is created.

If the scope is instantiated with RequiresNew, a new transaction scope will be created. The operations will not be part of an ambient transaction.

If the scope is instantiated with Suppress, it never takes part in a transaction, whether or not an ambient transaction is present.
