Visual Studio offers several ways to collect, view, and analyze code performance data. In many cases, the best way to get started with performance tools is to use the default settings of the Performance Wizard. The wizard collects app statistics that can point to performance issues in your code.
Performance warnings that notify you of common coding issues appear in the Visual Studio Error List window. You can navigate from the warnings to your source code, and to detailed help topics that help you write more efficient code.
Performance reports provide views on different levels of your application structure, source code lines, and processes. Performance reports show app execution data, from the calling and called functions of a specific function to the call tree of the entire app.
To quickly profile a project, app, or ASP.NET website, select Debug > Performance Profiler, and select Performance Wizard. For detailed instructions, see Beginners guide to performance profiling and How to: Collect performance data for a website.
To manually specify and configure a performance profiling session, select Debug > Profiler > Performance Explorer. Use the Targets folder and Properties pages in Performance Explorer to configure sessions. For instructions, see How to: Manually create performance sessions.
