Visual Studio offers a powerful debugger to aid with testing and troubleshooting your applications. One of the most common uses of a debugger is to set breakpoints, which are positions in the code that, when reached, cause the program execution to pause, allowing the developer to inspect the code and state of the program. When a breakpoint is reached and the application suspended, the application is in break mode. In break mode, you, the developer, can examine and change the values of the program variables. The simplest way to add a breakpoint to a particular line of code is to click in the margin...

Parallel Development As demands for application performance increased, customers have traditionally solved the problem by simply increasing the underlying power of the hardware that the application is running on. Over the last several years developers have seen the CPUs that their applications run on start to include 2, 4 or more cores. While the power of the hardware has increased, the transition to a multi-core environment has impacted the applications that developers write. The majority of applications will not be able to automatically take advantage of this multi-core hardware change. Developers...
