missing dotnet-sdk8 (or even only runtime) - plugin silently fails after starting up

[jkone27]

would be better to warn user if dotnet-sdk 8 is not installed, as for now if missing and no runtime is found, Fable.Daemon silently fails to compile and plugin hangs

bun run dev

here what I changed to make it work (had a new Mac installation)

➜  my-vue-app git:(main) ✗ dotnet --list-sdks    
8.0.410 [/usr/local/share/dotnet/sdk] <<<<<<
9.0.300 [/usr/local/share/dotnet/sdk]
➜  my-vue-app git:(main) ✗ dotnet --list-runtimes
Microsoft.AspNetCore.App 8.0.16 [/usr/local/share/dotnet/shared/Microsoft.AspNetCore.App] <<<<<<<
Microsoft.AspNetCore.App 9.0.5 [/usr/local/share/dotnet/shared/Microsoft.AspNetCore.App]
Microsoft.NETCore.App 8.0.16 [/usr/local/share/dotnet/shared/Microsoft.NETCore.App] <<<<<<< 
Microsoft.NETCore.App 9.0.5 [/usr/local/share/dotnet/shared/Microsoft.NETCore.App]

for Mac users: brew tap isen-ng/dotnet-sdk-versions brew install --cask dotnet-sdk8

relates to https://github.com/fable-compiler/vite-plugin-fable/pull/46 which should now allow for higher versions

[jkone27]

as an idea, maybe the plugin could run dotnet --list-runtimes at startup as pre check and verify if at least 8.x is installed?

Prechecks are a good idea, but avoid running them every time. Write a small marker file to disk and skip the check on subsequent runs.
