In this chapter, you created a trivial example COM component and implemented it in a DLL. You used it as an in-proc server or as a local server and even controlled its life cycle and idle time management by configuring the component (actually its containing application) differently. All this was achieved without changing a single line of code on the object or the client side. This achievement reflects the power of COM+: it enables you to focus on your product and domain problems at hand, while declaratively taking advantage of available services. The rest of this book discusses these services thoroughly, including their interactions and pitfalls, and provides tips and tricks for how to apply them productively.
