A Guided Garden Stroll through the .NET Framework Class Library

Namespace: SYSTEM.ENTERPRISESERVICES

● I am the EnterpriseServices Namespace and I enable a long list of COM+ Services in your .NET based applications.

The services that COM+ offers that can be used in .NET applications includes the following:

• Automatic Transaction Processing which allows you to mark your objects with attributes to indicate whether your object participates in an existing transaction, requires a transaction, starts a new transaction, etc. So .NET objects in your application can take part in multi-database transactions, even if the databases are from different vendors.
• BYOT (Bring Your Own Transaction) which allows your .NET components to participate in externally initiated transactions, such as from the Transaction Internet Protocol, Object Transaction Services, DTC and others.
• COM Transaction Integrator which provides access to IBM Main Frame CICS and IMS.
• Compensating Resource Managers (CRM) which allows the Microsoft Distributed Transaction Manager to give "all or nothing" support to your objects that don’t participate in standard database transactions.
• Just In Time (JIT) activation support so that your object’s context remains in memory, but any resources it is consuming get released until the next time the object is used.
• Loosely Coupled Events so that your objects can participate in a subscription based event model.
• Object Pooling which provides a pool of your objects ready-made that speeds up applications, particularly applications whose objects’ creation is process intensive and therefore time consuming.
• And Queued Components, Role-Based Security and several other features of COM+ Services.
