 Several Visual Studio user interface elements help you debug multithreaded apps. This article introduces multithreaded debugging features in the code editor window, **Debug Location** toolbar, and **Threads** window. For information about other tools for debugging multithreaded apps, see [Get started debugging multithreaded apps](../debugger/get-started-debugging-multithreaded-apps.md).
