This session highlights two useful features in Visual Studio 2005 that help developers improve the performance and quality of their software. Learn how the built-in profiler monitors the execution of a running program and generates detailed reports on the application's behavior that can be used to identify those bottlenecks that most affect the program's performance. We will also show how to take advantage of the support for test-driven development in Visual Studio 2005 to ensure that you are preserving the integrity of your existing code as you enhance or extend your solutions.
