I'm sorry guys but we're going to need some more info on this, as I can't reproduce it on my windows 11 box:

Installing dotnet sdk / runtime 10 on my machine fixed the issue for me.
Question: when grate is build as a selfcontained executable is the runtime on the machine still needed?

[wokket]

No, self-contained shouldn't need the runtime. It's possible we need to use a self-contained in the tool package, trading runtime flexibility for tool download size/time in pipelines. We could also look at whether we can include multiple copies of the tool, one for each supported runtime, but I'm definitely at the edge of my knowledge there.

This maybe an interesting article regarding this issue.

This is a problem with .NET 8 also

To reproduce:

dotnet-tools.json

{
  "version": 1,
  "isRoot": true,
  "tools": {
    "grate": {
      "version": "2.0.5",
      "commands": [
        "grate"
      ],
      "rollForward": false
    }
  }
}

global.json

{
  "sdk": {
    "version": "8.0.0",
    "rollForward": "latestFeature",
    "allowPrerelease": false
  }
}

I'm away from the computer for a bit and don't know much about the dotnet-tool tooling. If anyone is willing to throw a PR in it would be appreciated
