Visual Studio Debug only user code with Just My Code

By default, the debugger skips over non-user code (if you want more details, see Just My Code).

Just My Code is a Visual Studio debugging feature that automatically steps over calls to system, framework, and other non-user code. In the Call Stack window, Just My Code collapses these calls into [External Code] frames.

Just My Code works differently in .NET, C++, and JavaScript projects.

Visual Studio Enable or disable Just My Code

For most programming languages, Just My Code is enabled by default.

• To enable or disable Just My Code in Visual Studio, under Tools > Options (or Debug > Options) > Debugging > General, select or deselect Enable Just My Code.

Enable Just My Code is a global setting that applies to all Visual Studio projects in all languages.
