Steps taken.

Open neovim at project solution root
Open up a cs file in a project that is part of the solution

At first I thought it was a conflict due to not disabling the omnisharp server startup from vim-omnisharp. But I got the same error when configuring that to not start up its omnisharp server.

Same issue, on Arch

I was able to get to a different error by copying a runtimeconfig.json file from a hello world project’s bin:

admicos ~/src/asd/bin/Debug/netcoreapp2.2 $ cp asd.runtimeconfig.json ~/.config/coc/extensions/node_modules/coc-omnisharp/omnisharp/omnisharp/OmniSharp.runtimeconfig.json

the second error is:

System.IO.FileNotFoundException: Could not load file or assembly 'System.Security.Permissions, Version=0.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. The system cannot find the file specified.

Edit: Launching OmniSharp.exe with mono from the command line doesn’t show any errors, so maybe try that?

Edit 2: setting "omnisharp.useDotnet": false, in :CocConfig works… Somewhat…

@mihaelartz don’t worry. You’re helping a lot by testing it out 😃

Please try 0.0.7 – I’ve added an option to specify how to start omnisharp – defaults to dotnet – make sure you have dotnet core installed.

hmm, autocompletion started to work after some time:

yatli on Jul 14, 2019

Yeah, it doesn’t look like Omnisharp is helping a lot here

yatli on Jul 14, 2019

sorry for the trouble, some dumb mistakes… please try 0.0.5

yatli on Jul 14, 2019

@yatli this line: https://github.com/yatli/coc-omnisharp/blob/master/src/client/platform.ts#L76

change to: const omnisharpDirectory = path.join(__dirname, "..", "..", "omnisharp/omnisharp")

and, mono must be installed manually via https://www.mono-project.com/download/stable/

after this changes, i don’t get any errors, but completion is week, i don’t get completions for class methods, attributes, namespaces…

you mean, for Linux it’s not a self-contained dotnet application?
