Assembly: System.Management.Automation (in System.Management.Automation.dll)
Return ValueA Boolean value that indicates true if a transaction is available for the cmdlet to participate in. If the cmdlet supports transactions, it can participate in transactions and the action of the cmdlet can be committed to or rolled back.
Windows PowerShell transactions allow you to perform several actions as a group. If all the actions succeed you can accept the transaction. If any one of the actions fail, you can roll back the transaction.
Transactions are started only when the Start-Transaction cmdlet is run. When started, the Complete-Transaction cmdlet can be run to accept the actions of the cmdlets that participated in the transaction, or the Undo-Transaction cmdlet can be run to roll back the actions made by those cmdlets. Not all cmdlets that are run between when the Start-Transaction cmdlet and the Complete-Transaction cmdlet or the Undo-Transaction cmdlet are called, will participate in the transaction. Only those cmdlets that have their RequiresTx parameter set to true can participate in the transaction.
