Chapter 30. Enterprise Services
Enterprise Services is the name of the Microsoft application server technology that offers services for distributed solutions. Enterprise Services is based on the COM+ technology that has already been in use for many years. However, instead of wrapping .NET objects as COM objects to use these services, .NET offers extensions for .NET components to take direct advantage of these services.

This chapter covers the following topics:
