As a developer, navigating through complex codebases can be overwhelming, especially when working on large-scale projects. Visual Studio, a popular integrated development environment (IDE), offers a feature called “Just My Code” to help simplify the debugging process and improve productivity. In this article, we will delve into the world of “Just My Code,” exploring its benefits, functionality, and best practices for utilizing this powerful tool.
What is “Just My Code” in Visual Studio?
“Just My Code” is a feature in Visual Studio that allows developers to focus on their own code while debugging, ignoring non-user code such as system libraries, frameworks, and other external dependencies. This feature is particularly useful when working on large projects with multiple dependencies, as it helps to reduce noise and distractions, making it easier to identify and fix issues.
How Does “Just My Code” Work?
When “Just My Code” is enabled, Visual Studio uses a combination of heuristics and settings to determine which code is considered “my code” and which is not. The IDE analyzes the codebase, taking into account factors such as:
- Project boundaries: Code within the current project is considered “my code.”
- Symbol files: Visual Studio uses symbol files (PDBs) to determine which code is user-written and which is not.
- Attributes: Certain attributes, such as the
System.Diagnostics.DebuggerNonUserCodeAttribute, can be used to explicitly exclude code from “Just My Code.”
By filtering out non-user code, “Just My Code” provides a more streamlined debugging experience, allowing developers to focus on the code that matters most.

What is “Just My Code” in Visual Studio?
“Just My Code” is a feature in Visual Studio that allows developers to focus on their own code while debugging, hiding non-user code such as system and framework code. This feature is designed to simplify the debugging process by filtering out irrelevant code and highlighting the code that is most relevant to the developer’s current task.
When “Just My Code” is enabled, Visual Studio will automatically skip over non-user code when stepping through code, making it easier to identify and fix issues in the developer’s own code. This feature can be especially useful when working on large projects or when debugging complex issues that involve multiple layers of code.
How do I enable “Just My Code” in Visual Studio?
To enable “Just My Code” in Visual Studio, go to the “Tools” menu and select “Options.” In the “Options” dialog box, navigate to the “Debugging” section and check the box next to “Enable Just My Code.” You can also enable “Just My Code” on a per-project basis by right-clicking on the project in the Solution Explorer and selecting “Properties,” then navigating to the “Debug” tab and checking the box next to “Enable Just My Code.”
Once “Just My Code” is enabled, you can verify that it is working by starting a debugging session and stepping through your code. If “Just My Code” is enabled correctly, Visual Studio should skip over non-user code and focus on your own code.
What are the benefits of using “Just My Code” in Visual Studio?
The main benefit of using “Just My Code” in Visual Studio is that it simplifies the debugging process by filtering out irrelevant code.
