Debugging Command Line Applications in Visual Studio

Understanding the Command Line Debugger

Debugging command line applications can be a perplexing and challenging task, especially if you are new to Visual Studio. Once you get past the initial bewilderment, however, you can easily troubleshoot most issues by using Visual Studio’s command line debugger. This powerful tool allows you to step through your C++, C#, VB.NET, Python, and other applications, set breakpoints, and inspect variables in real-time. Despite its many advantages, the command line debugger comes with its set of challenges. Since command line applications lack GUI features such as forms and buttons, developers must rely on different sets of tools to interact with the application, especially when debugging it.

Step 1: Creating a Command Line Application in Visual Studio

Before you debug a command line application, you must have one to debug. To create a new command-line application in Visual Studio, start by opening up the software and clicking on “Create a new project.” In the “New Project” dialogue box, select “Console App” under “Visual C++” and give it a name. Click on “Create” to complete the process. In the solution explorer, you should now see your new project’s files.

Step 2: Adding a Breakpoint

Setting a breakpoint is a critical step in debugging applications in Visual Studio. This feature allows you to pause the execution of the application at a given location in its code to inspect variables, call stacks, and evaluate expressions. To add a breakpoint, first, open the code file you wish to debug. Click on the left margin of the line you want to set the breakpoint on. You can set as many breakpoints as required.

Step 3: Running the Command Line Application in Debug Mode

After adding a breakpoint, you are ready to run the application in debug mode. Open the debug menu and click on “Start debugging,” or press F5. Visual Studio will then start your application in debug mode, and the application will pause at the breakpoint you set. You can now interact with the application using the debugging tools.

Step 4: Understanding the Debugger Windows

To debug your command-line application efficiently, you must understand the various debugging windows provided by Visual Studio. Some popular windows that you can use to debug include Autos, Locals, Watch, Call Stack, and Breakpoints. These windows will help you pinpoint where the issue lies in your code.

Step 5: Running the Application Step by Step

Once you understand the different debugging windows and know how to set breakpoints, you can run your application step-by-step to debug it efficiently. To execute the current line and step into a function call, press F11 or use “Step Into” in the “Debug” menu. Use “Step Out” in the “Debug” menu to finish executing the current function and return to the calling function.


Debugging command-line applications doesn’t have to be complicated, provided you know how to use the command-line debugger in Visual Studio. By following the steps outlined in this article, you can easily identify and fix issues in your command-line applications. Set breakpoints for your code and use the debugging windows to identify where the issue is. With the powerful debugging tools available in Visual Studio, you can effectively troubleshoot your command-line applications in no time.
