Summary
In this chapter, we've investigated the best ways to track down our coding problems. We've looked at the various debug tracing outputs that we have access to and even discovered how to output our own custom trace information. We discovered that the exceptions that are thrown in WPF often hide their useful information in their InnerException
properties. Finally, we found out a number of tips and tricks to use when trying to find errors with our data bound values.
The next chapter delves deeply into the subject of application frameworks and we get started on constructing our own. We find out about the benefit of base classes and discover alternative ways to implement our framework functionality. The chapter will finish off by investigating a variety of techniques to ensure that our applications maintain the essential Separation of Concerns that MVVM provides.
