Building Serviced Components (COM+ Interop)

The .NET platform provides a specific assembly, System. EnterpriseServices.dll, which allows you to build managed code libraries that can leverage the services provided by the COM+ runtime. Thus, using C#, VB.NET, or any other managed language, you are able to build types that can support the same behaviors (for example, automated transactions, JITA, role-based security, and whatnot) as a classic COM+ type. The point of this chapter is to provide an overview of the key features of COM+, as well as to dig into the details of building configured components under the.NET platform. As you will see, building COM+-aware.NET types is similar to the process of exposing .NET types to a classic COM client (as described in Chapters 10 through 12). These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
