No default debug configuration

[Eliemer]

Describe the bug

when starting a fresh project and going to the "debug and run" pane, there's no longer any Ionide automatic configurations in the dropdowns.

Steps to reproduce

1. New dotnet project
2. Open "Run and Debug" pane
3. click "Show all automatic debug configurations"

Expected behaviour

There should be Ionide configs in that dropdown.

@baronfel is this something we have to pester the C# plugin about?

[baronfel]

Ours should be under the .NET Core drop-down selection there, IIRC?

[Eliemer]

When i click the .NET Core dropdown i get an empty search bar i think?

That said, when i manually run F#: Debug default project everything works as intended.

So it seems like the C# plugin is just ignoring all fsproj files in any of their pickers.

You'll have to click create a launch.json file

It'll still pop up some selection. Just choose something to get the file created. This seems like a VSCode UX problem where it won't just create the file for you.

You might have something in the file already configured, otherwise just clear it so it's nice and pristine:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": []
}

You can then type in the configuration array and find some .NET configurations.

Selecting something like console and filling in the bits for the dll path should result in something like:

{

    "version": "0.2.0",
    "configurations": [
        {
            "name": ".NET Core Launch (console)",
            "type": "coreclr",
            "request": "launch",
            "preLaunchTask": "build",
            "program": "${workspaceFolder}/bin/Debug/net8.0/fsharp-playground",
            "args": [],
            "cwd": "${workspaceFolder}",
            "stopAtEntry": false,
            "console": "internalConsole"
        }
    ]
}

It should then show up in the panel for you click on:

Then you should be able to debug.

Be sure to use the coreclr type. And of course you can't use dotnet to select an fsproj

The following works for me as a manual workaround to achieve F5 debugging:

./.vscode/launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": ".NET Core Launch (console)",
            "type": "coreclr",
            "request": "launch",
            "preLaunchTask": "build FSDebugging.fsproj",
            "program": "${workspaceFolder}/bin/Debug/net8.0/FSDebugging.dll",
            "args": [],
            "cwd": "${workspaceFolder}",
            "stopAtEntry": false,
            "console": "internalConsole"
        }
    ]
}

./.vscode/tasks.json

{
	"version": "2.0.0",
	"tasks": [
		{
			"label": "build FSDebugging.fsproj",
			"type": "shell",
			"command": "dotnet build ${workspaceFolder}/FSDebugging.fsproj",
			"problemMatcher": []
		}
	]
}
