In Visual Basic 6.0, you can use the MTSTransactionMode property to set the transactional behavior of a user class. This property is only used by components that are running in the Microsoft Transaction Server, and has no effect if the component is run outside of the MTS. In Visual Basic .NET, developers can use System.EnterpriseServices namespace to get transactional functionality for their .NET classes. To be treated as a transactional class, a Visual Basic .NET class should inherit from ServicedComponent and include the proper transaction attribute. Transactional Visual Basic 6.0 classes should be upgraded to serviced components. The MTSTransactionMode values correspond to the System.EnterpriseServices.TransactionOption .NET Framework enumeration that contains the automatic transaction type requested by a COM+ component. To create a Visual Basic .NET project that references transactional classes, the latter should inherit from ServicedComponent and contain transactional attributes,
