Launch debug error (Couldn't find a debug adapter descriptor for debug type 'dotnet')

[mcm-ham]

Type: Bug

Launch configuration works fine in launch.json:

{
  "name": "C#: WebApp Debug",
  "projectPath": "${workspaceFolder}/WebApp.csproj",
  "request": "launch",
  "type": "dotnet"
}

But when placed in workspace file under "launch" I get the Couldn't find a debug adapter descriptor for debug type 'dotnet' error. The launch & task configuration that gets generated from older version of extension still works in workspace file.

@mcm-ham what that error means is that VS Code was unable to communicate with the C# extension.

Questions:

1. A new release of the C# extension came out today. If you update, does it still repro? I doubt anything in the new version fixed it, but maybe just installing another version will help.
2. If it doesn't, do you see a 'C#' output window tab? If so, can you past whatever it shows there?

[mcm-ham]

1. Just updated to v2.7.25 no difference.
2. Yes I do, here's the output after attempting to debug:

Very strange. If you clone this repo locally and follow these instructions to run the experimental instance, does this issue reproduce for you in the experimental instance?

If it does reproduce under the experimental instance, and you have the time to debug it, here is where the dotnet debugger type should be getting registered. That function (registerDebugger) is called from activateRoslynLanguageServer, which I can see from your tracing is called.

@Sujay-WSD did the error you saw have any additional information? That error message looks truncated and doesn't really tell me anything.

@Sujay-WSD apologies for the late reply, are you still having issues on the latest versions of the extensions? If so can you post the most up to date logs?
