netcoreapp3.1 Nuget.Framework could not be loaded on Linux.

[ErikFeeley]

To reproduce, create a new netcoreapp3.1 project on linux ( I am on Manjaro ). Open up vim / nvim. Project fails to load.

Interestingly loading a netcoreapp2.1 project works fine.

CocInfo details below.

Added netcoreapp3.1 and published a new version. Use fsharp.downloadLanguageServer to pull that.

[ErikFeeley]

Thanks for the update! I cleared out coc-fsharp-data from my ./config/coc/extensions and re-installed the extension. When opening a netcoreapp3.1 or netcoreapp2.2 project I receive this error

[coc.nvim] Installed extension: coc-fsharp [coc.nvim] Error on active extension coc-fsharp: TypeError: Cannot read property 'browser_download_url' of undefined at LanguageServerProvider.<anonymous> (/home/erik/.config/coc/extensions/node_modules/coc-fsharp/node_modules/coc-utils/out/platform.js:88:42) at Generator.next (<anonymous>) at fulfilled (/home/erik/.config/coc/extensions/node_modules/coc-fsharp/node_modules/coc-utils/out/platform.js:5:58) at runMicrotasks (<anonymous>) at processTicksAndRejections (internal/process/task_queues.js:97:5)

@ErikFeeley also see https://github.com/coc-extensions/coc-fsharp/issues/12, same problem. Perhaps the auto download mechanism has failed.

[yatli]

Fixed. Please try again.

[ErikFeeley]

It works! Thanks so much! Fantomas works as well now which if I remember it did not run for me previously :)

[yatli]

Closing the issue now. Feel free to reopen if problem comes back.
