Les assemblys de référence pour le framework ".NETFramework, Version = v4.7.1" sont introuvables

J'essaie d'ouvrir un projet Unity3D avec VSCode sous Linux (Ubuntu 18.10). L'extension omnisharp ne charge pas le projet, car les assemblys sont introuvables.

Cela peut sembler très stupide, mais je ne suis pas encore vraiment habitué à .Net, et je suis coincé avec cette erreur depuis plusieurs jours maintenant. J'ai essayé de réinstaller dotnet (même en utilisant le package snap), mono, vscode et l'extension omnisharp.

Toute aide est donc la bienvenue! :)

J'ai eu le même problème mais sur OSX. L'installation de la dernière version de Mono a supprimé les références manquantes du framework .net v4.7.1.

J'ai installé Mono V5.18.0 à partir de https://www.mono-project.com/download/stable/

J'espère que ça marche pour toi.

J'étais dans la même situation et j'ai trouvé une solution de contournement ici: https://github.com/Microsoft/msbuild/issues/2728

Vous devez export FrameworkPathOverride=/lib/mono/4.5 et le .NETFramework sera trouvé.

  1. Dans Linux Mint 18.3 Sylvia (Ubuntu 16.04) installe mono-devel comme https://www.mono-project.com/download/stable/#download-lin .

  2. Exécutez ensuite dans le terminal export FrameworkPathOverride=/etc/mono/4.5

  3. Open vs code et fonctionne.
