• OS Version: Ubuntu 24.04.1 LTS (WSL2)

Steps to Reproduce:
I'm on WSL2 (Ubuntu):

1. Install the C# extension.
2. Add a .vscode/launch.json like this following (the key bit being "console": "externalTerminal".

{
	// Use IntelliSense to learn about possible attributes.
	// Hover to view descriptions of existing attributes.

	"version": "0.2.0",
	"configurations": [
		{
			"name": ".NET Core Launch (web)",
			"type": "coreclr",
			"request": "launch",
			"preLaunchTask": "build",
			"program": "${workspaceFolder}/artifacts/bin/Shenas.Server/debug/Shenas.Server.dll",
			"args": [],
			"cwd": "${workspaceFolder}/src/Shenas.Server",
			"stopAtEntry": false,
			"console": "externalTerminal",
			"env": {
				"ASPNETCORE_ENVIRONMENT": "Development"
			},
			"sourceFileMap": {
				"/Views": "${workspaceFolder}/Views"
			}
		},
		{
			"name": ".NET Core Attach",
			"type": "coreclr",
			"request": "attach"
		}
	]
}

3. Set the external terminal path (Linux) in user settings to /mnt/c/Users/USER_NAME/AppData/Local/Microsoft/WindowsApps/wt.exe -w 0 (replace USER_NAME with your user)

4. Launch the debugger through this profile — the following error will appear:

Googled the error but couldn't find anything relevant. If this is fixable on my end, please let me know.

Please file on the repo for the C# extension

@roblourens this doesn't sound like an issue with the C# extension, this sounds like a VS Code issue.
