OmniSharp.MSBuild.ProjectManager Failed to load project on Linux

Question

I am learning C# on my Manjaro Linux Notebook. I tried to install the ms-vscode.csharp extension, but when opening any .NET Core project I get the following Error Message:

Answer 1

This seem to have done it for me code -> preferences -> settings -> click this

;/ wish i had at least 10 reputation to post a picture here but it's the first icon in the top right looks like a lil piece of paper.

Then..

copy pasta this into settings.json

{
  "explorer.compactFolders": false,
  "update.mode": "none",
  "workbench.iconTheme": "vscode-icons",
  "editor.formatOnSave": true,
  "editor.defaultFormatter": "esbenp.prettier-vscode",
  "omnisharp.path": "latest",
  "omnisharp.monoPath": "auto",
  "csharp.semanticHighlighting.enabled": true,
  "editor.formatOnType": true,
  "[csharp]": {
    "editor.defaultFormatter": "ms-dotnettools.csharp"
  },
  "[xml]": {
    "editor.defaultFormatter": "DotJoshJohnson.xml"
  },

  "settingsSync.ignoredExtensions": [],
  "window.zoomLevel": 0
}

that ^

"[csharp]": {
    "editor.defaultFormatter": "ms-dotnettools.csharp"
  },
  "[xml]": {
    "editor.defaultFormatter": "DotJoshJohnson.xml"
  },

but i think this is what did the trick for me ^ specifically the [csharp]
