Failed to load project: [.csproj files]

[AndrGutierrez]

I already opened an issue of autocompletion and linting not working in unity projects and I realized that it probably is because of this error

Failed to load project:

it says that about all the .csproj files. Thank you for your time

In your other issue I referred you to issue #707, which these issues are duplicates of. Did you try telling OmniSharp-vim to use the mono version of OmniSharp-roslyn, as described in #707?

[AndrGutierrez]

yes, I tried it, it didn't work.

As far as I know that's a mac issue, anyways I tried it but nothing happened

[nickspoons]

No, it's not a Mac issue. OP in issue #707 is using manjaro.

Unity uses .NET Framework, which means you need mono to run it on non-Windows systems.

Please follow the instructions in this comment and then post your log (:OmniSharpOpenLog)

I already did, but then I commented the mono line, restarted vim, uncommented the same line and opened the project, it worked PERFECTLY... then I restarted vim to check that it would work a second time and it didn't...

at least I don't have the load files error anymore

here is my log, it is too long, it doesn't have any fail messages

404.

Is this file in a private repo?

I already did, but then I commented the mono line, restarted vim, uncommented the same line and opened the project, it worked PERFECTLY... then I restarted vim to check that it would work a second time and it didn't...

I don't know how to interpret this. Was it the same project both times? Was there a .csproj and .sln both times (my understanding is that unity creates these on the fly and they are not always available)? The log will tell you this.

1. Add let g:OmniSharp_server_use_mono = 1 to .vimrc
2. Restart vim
3. :OmniSharpInstall
4. Open project
5. Verify that :echo g:OmniSharp_server_use_mono outputs 1
6. Post log

[AndrGutierrez]

yeah, the repository was private, I am stupid, it is public now

OK, this looks like the problem:

[dbug]: OmniSharp.CompositionHostBuilder
        .NET SDK requires MSBuild instances version 16.8.0 or higher

        It looks like you have Mono 6.4.0 or greater installed but MSBuild could not be found.
Try installing MSBuild into Mono (e.g. 'sudo apt-get install msbuild') to enable better MSBuild support, or upgrade to latest Mono: https://www.mono-project.com/download/stable/.

Here's what mine looks like:

I'm using the mono-msbuild package on arch, give that a go.

[AndrGutierrez]

it worked! but just for autocompletion for some reason the errors like:

The type or namespace name 'UnityEngine' could not be found

keep appearing

[nickspoons]

It's not loading those Unity libraries for whatever reason, there are probably details in the log
