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.

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.

To set this compiler option in the Visual Studio development environment:

1. Open the project’s Property Pages dialog box. For details, see Set C++ compiler and build properties in Visual Studio.
2. Select the Configuration Properties > C/C++ > General property page.
3. Modify the Support Just My Code Debugging property, then the setting will only apply to this project.
