Missing Microsoft.CodeAnalysis.Workspaces when using a workspace

[Scriptodude]

I currently work on several projects on the side with a folder structure similar to the following:

root/
  project-1/
    backend/ <- csharp project
    frontend/ <- typescript project
  project-2/
    backend/ <- csharp project
    frontend/ <- typescript project

I tried configuring the extension to use such folder structure:

"lsp": {
    "roslyn": {
      "settings": {
        "workspace": {
          "workspaceFolders": [
            {
              "uri": "./project-1/backend",
              "name": "p1-backend",
            },
            {
              "uri": "./project-2/backend",
              "name": "p2-backend",
            },
          ],
        },
      },
    },
 },

However with or without the configuration I get the following error from roslyn:

Language server roslyn:

-- stderr --
Unhandled exception. System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.CodeAnalysis.Workspaces, Version=5.4.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified.

I believe the csharp-language-server tool is missing a configuration - should I open a bug on their side also ?

Are you still experiencing this issue? We recently removed csharp-language-server and are now downloading Roslyn directly.

@reflectronic i'm using csharp-ls with this extension, works flawlessly.

As for the multi-project, i created a .slnx at the root importing all backend projects. csharp-ls automatically discovers it and the language server works as expected.

If someone can retry / confirm this issue tho, it would be great.
