If you're only interested in debugging a Python script, the simplest way is to select the down-arrow next to the run button on the editor and select Debug Python File in Terminal. The best way to explain the difference between launch and attach is to think of a launch configuration as a recipe for how to start your app in debug mode before VS Code attaches to it, while an attach configuration is a recipe for how to connect VS Code's debugger to an app or process that's already running. The Terminal tab might not display the string you enter while you're entering it, but the Console.ReadLine method will capture your input. Download Visual_Studio_Loader.zip - 35.9 KB; Introduction.

As soon as a second session is up and running, the VS Code UI switches to multi-target mode: An alternative way to start multiple debug sessions is by using a compound launch configuration. Even if you do start the executable outside Visual Studio, you can still use the "Attach" command to connect Visual Studio to your already-running executable. The values in the file did not show up in VS, Project Properties, Debugging. The Python extension automatically detects breakpoints that are set on non-executable lines, such as pass statements or the middle of a multiline statement. In short, the Visual Studio debugger can be invoked on a program from the command line, allowing one to specify the command line arguments when invoking a command line program, directly on the command line.

Preparing to debug a Console project is similar to preparing to debug a Windows project, with some additional considerations such as setting command-line arguments and how to pause the app for debugging. Inline breakpoints can also have conditions. This is particularly useful when debugging minified code which contains multiple statements in a single line. *Note: When the debugger performs a reload, code that runs on import might be executed again. The release configuration of a program has no symbolic debug information and is fully optimized.
