The complexities of today's software are better managed used techniques such as layered architectures, object-oriented programming, separation of concerns, MVC, and MVVM to name a few. All of these techniques require that your application be separated into logical units, which means that to perform any task, your code needs to call other pieces of code. For example, in the "old days" your application may have had all of the code that retrieved data and bound it to a grid in one OK Click event handler. Now, the OK Click event handler in the presentation layer may call a command handler in a view which calls a method in a business object of your business layer which calls a method to actually retrieve the data from your data access layer. The Call Stack Window helps you see these paths through your code and allows you to quickly navigate between them. To see the Call Stack window, put a break point somewhere in your code. Run the application. When the application hits the break point, use Debug | Windows | Call Stack to view the Call Stack window:
