omnisharp

https://github.com/omnisharp/omnisharp-roslyn OmniSharp server based on Roslyn workspaces

omnisharp-roslyn can be installed by downloading and extracting a release from here. Omnisharp can also be built from source by following the instructions here.

Omnisharp requires the dotnet-sdk to be installed.

By default, omnisharp-roslyn doesn't have a cmd set. This is because nvim-lspconfig does not make assumptions about your path. You must add the following to your init.vim or init.lua to set cmd to the absolute path ($HOME and ~ are not expanded) of the unzipped run script or binary.

local pid = vim.fn.getpid()
-- On linux/darwin if using a release build, otherwise under scripts/OmniSharp(.Core)(.cmd)
local omnisharp_bin = "/path/to/omnisharp-repo/run"
-- on Windows
-- local omnisharp_bin = "/path/to/omnisharp/OmniSharp.exe"
require'lspconfig'.omnisharp.setup{
    cmd = { omnisharp_bin, "--languageserver" , "--hostPID", tostring(pid) };
    ...
}

Note, if you download the executable for darwin you will need to strip the quarantine label to run: 

find /path/to/omnisharp-osx | xargs xattr -r -d com.apple.quarantine

Setup

require'lspconfig'.omnisharp.setup{}

Default values

filetypes = { "cs", "vb" }
init_options = {}
root_dir = function(fname)
      return util.root_pattern '*.sln'(fname) or util.root_pattern '*.csproj'(fname)
    end,
