No response

FYI for ppl following this: I tried debugging this myself. It seems harder to work on this as a beginner on this repo than I thought. My thoughts so far:

CONTRIBUTING.md starting guide isn't complete.

Validating plug-in changes locally

The recommended way to validate your changes is to deploy the plugin locally to a fresh nx workspace.
* A sandbox workspace can be generated via `yarn sandbox`
* This script will build/publish the plugin to a sandbox workspace (./tmp/sandbox)
* Verdaccio is leveraged to start a locally running instance of npm (http://localhost:4872/)
    The server will close when the script is stopped
* use `nx generate @nx-dotnet/core:[generator]` to validate your changes manually
yarn sandbox references files that do not exist: https://github.com/EelcoLos/nx-dotnet/blob/6dc1e995be359f372da506c65e1e20ccd6682ca3/tools/scripts/sandbox.ts#L11C1-L12C1

and publish-all https://github.com/EelcoLos/nx-dotnet/blob/6dc1e995be359f372da506c65e1e20ccd6682ca3/tools/scripts/sandbox.ts#L24C6-L24C7 , which was removed in https://github.com/nx-dotnet/nx-dotnet/pull/874 (file itself: https://github.com/nx-dotnet/nx-dotnet/blob/5f0dd3a49717e12a7fe788c729c4a35c4bb7adc9/tools/scripts/publish-all/index.ts)

Most importantly: This plugin references NXPluginV1, whereas v20 demands NXPluginV2 on various files. This migration will have some work in here, but is doable i guess.
I almost got it to work, then the final test of the sandbox tries to test to a create-nx-workspace with preset empty. This preset doesn't exist any more. Also, when trying to execute this, I get a Failed to create nx workspace error, without being able to dive deeper.

Hope this'll at least inform you. My question is: should I log these as seperate issues? And if so, as it's needed for this package to move forward, still be part of the same work?
