We discussed the factory pattern (under the Factories section) to help us in our efforts for loosely coupled objects of our application. We have also said that we plan to use a Test- Driven Development process. In order to achieve both of these easily, we will be using a framework called StructureMap. Get more information on http://structuremap.sourceforge.net/Default.htm. StructureMap is a dependency injection framework. Its primary goal is to help us to reduce the mechanical costs of good object-oriented design. It also helps us to have a more flexible application for testing purposes.

StructureMap is very easy to use. I have mostly covered how to get it set up in Appendix A at the end of the book. But if you don't want to read that now, I will give you a down and dirty here. Once you have downloaded the StructureMap files, add them to your bin directory. Then add a reference to the StructureMap in your projects. Add an XML file to your solution and share...
