Specifies the transaction isolation level.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
The isolation level in which your transaction runs determines how data is treated when changes are made in other transactions and how long your transaction must hold locks to protect against these changes. For example, the default value, Unspecified, specifies that no updating or inserting can occur until the transaction is complete.
