Can't find .NET Core MSBuild when using ASDF
When trying to run it, the server starts but then crashes because it can't find any SDK. I installed the dotnet SDK using ASDF with the dotnet plugin, so there is probably a misconfiguration. Both DOTNET_ROOT and MSBuildSDKsPath are set.
This error is probably not directly related the csharp-ls, as I get the same error with Omnisharp, but I don't really know where else to ask for help.
This is the last message from the server.

Any idea about what I could do to solve it?
Ok, I figured it out. It seem that to find the SDK, the MSBuildLocator follows the dotnet symlink until it arrives to the real binary. But the dotnet executable in my path was just a shim created by ASDF.
Because the final executable was not the real SDK, the search failed. I solved by setting adding the real dotnet to the path.
Is there a Wiki or something where I can document this? It was pretty cryptic error.
Or maybe I should ping the mantainer for the ASDF plugin... I'm not sure.
If someone thinks this shouldn't be mentioned here, I'll just close the issue.
@hochata thank you! I wouldn't figure it out in a million years! In my case it helped to unlink/uninstall dotnet from brew and just install it manually, so that my only path (where dotnet) is /usr/local/share/dotnet/dotnet

I was able to fix the problem by uninstalling asdf with homebrew, deleting all of its plugin files manually and installing again; It was quite painful, but it worked.
