Visual Studio Code .NET Core debugger not hitting a breakpoint

Question

I have a problem trying to debug applications written in .NET Core in Visual Studio Code. Here is the setup: I'm using a virtual machine running Debian 9 (with the default GUI). I've installed .Net Core SDK 2.1, and Visual Studio Code 1.30.0. Installed the extensions for C# 1.17.1. I've created simple project:

class MyProgram
{
    static void Main(string[] args)
    {
        Console.WriteLine("Hello You Angel!");
        ProcessStartInfo startInfo = new ProcessStartInfo() { FileName = "/bin/bash", Arguments = "-c nautilus /home/", }; 
        Process proc = new Process() { StartInfo = startInfo, };
        proc.Start();
    }
}

If I run the program, in executes, and produces the correct output. In the debug window I pressed the gear button to edit the launch.jason file

Here it is what it looks like:

{
 "version": "0.2.1",
 "configurations": [
    {
        "name": ".NET Core Launch (console)",
        "type": "coreclr",
        "request": "launch",
        "preLaunchTask": "build",
        // If you have changed target frameworks, make sure to update the program path.
        "program": "${workspaceFolder}/HelloWorld/bin/Debug/netcoreapp2.1/HelloWorld.dll",
        "args": [],
        "cwd": "${workspaceFolder}/HelloWorld",
        // For more information about the 'console' field, see https://github.com/OmniSharp/omnisharp-vscode/blob/master/debugger-launchjson.md#console-terminal-window
        "console": "integratedTerminal",
        "stopAtEntry": false,
        "internalConsoleOptions": "openOnSessionStart",
        "externalConsole": false,
    },
    {
        "name": ".NET Core Attach",
        "type": "coreclr",
        "request": "attach",
        "processId": "${command:pickProcess}"
    }
 ,]
}

I've put a breakpoint in the project:

and when I hit the green triangle button, the breakpoint it not hit. Actually I think that non of the code i executed at all. Is there something I'm missing to get this app it debugging mode?

Please help!

Answer 1

I was having the same issue on a different setup. Running windows 10 using VSCode and dotnet sdk 2.2.

I found a few answers browsing through gissues Here.

And This one I think fixed my problem

I also noticed to make sure I was selecting the correct "c:/projectdir/bin/debug/projectname.dll" when asked to attach the debugger to a process.

After that VSCode successfully hit my breakpoint.

I hope this helps.

1) In terminal go to your project and write

dotnet restore
dotnet clean
dotnet build

2) Check paths of "program" and "cwd" in your configurations (launch.json).
