For some reason the metadata of the .ipynb files stay .net C# specific, and I need to edit them, so it would look like this:

"metadata": {
  "kernelspec": {
   "display_name": ".NET (PowerShell)",
   "language": "PowerShell",
   "name": ".net-powershell"
  },
  "language_info": {
   "file_extension": ".ps1",
   "mimetype": "text/x-powershell",
   "name": "PowerShell",
   "pygments_lexer": "powershell",
   "version": "7.4"
  }
 }

I'm experiencing the same problem with F#:

• every cell I add to the notebook defaults to C#,
• if I [Ctrl][Enter] run a F# cell, the next it creates is C#.

Initially it works ok, but after a while, the notebook's metadata gets set to:

 "metadata": {
  "kernelspec": {
   "display_name": ".NET (C#)",
   "language": "C#",
   "name": ".net-csharp"
  },
  "polyglot_notebook": {
   "kernelInfo": {
    "defaultKernelName": "csharp",
    "items": [
     {
      "aliases": [],
      "name": "csharp"
     },
     {
      "aliases": [],
      "languageName": "fsharp",
      "name": "fsharp"
     },
     {
      "aliases": [
       "js"
      ],
      "languageName": "JavaScript",
      "name": "javascript"
     }
    ]
   }
  }
 },
 "nbformat": 4,
 "nbformat_minor": 2
}

Yeah, this is super annoying.
