Roslyn initialized but not working

[marvindore]

Hello thank you for taking the time to make this plugin. I have made progress installing the plugin but can’t seem to get any of the LSP functionality to work. Here are my steps and observations:

1. I am running

• neovim nightly v0.10,
• LazyVim package manager
• Linux
• dotnet 7.

2. I installed the language sever using the :CSInstallRoslyn command which completed successful.
3. My config file is as follows:

   require(“roslyn”).setup({
   on_attach = function()
   vim.keymap.set("n", "gd", vim.lsp.buf.definition, {buffer=0})
   end,
   capabilities = require(‘lsp-status’).capabilities
   }

   end

4. When I open a C# project that has a .sln file at the root I get the following messages: Roslyn client initialized for target test.sln Roslyn project initialization complete.

When I type :LspInfo it says:

1 client(s) attached to this buffer:
Client: roslyn (id: 1, bufnr: [4]) 
filetypes: 
autostart: false
root directory: /home/tester/test
cmd: <function>
Configured servers list: lua_ls, jsonls, pyright, tsserver 

But there are no diagnostics, and goto definition is not working.

Edit: I also notice in init.lua the callback in M.setup_autocmds() is not firing. I added this print statement but it never executed:

function M.setup_autocmds()
    local lsp_group = vim.api.nvim_create_augroup("Roslyn", { clear = true })
    vim.api.nvim_create_autocmd("FileType", {
        pattern = { "cs" },
        callback = function(opt)
      print("init line 149 opt.buf ", opt.buf)
            M.init_buf_targets(opt.buf)
            M.attach_or_spawn(opt.buf)
        end,
        group = lsp_group,
        desc = "",
    })
end

Resolved, I got some assistance from @nilsgehlin where in his dotfiles I noticed I was not setting up capabilities correctly. I changed my capabilities to: local capabilies = vim.tbl_deep_extend("force", vim.lsp.protocol.make_client_capabilities(), require('cmp_nvim_lsp').default_capabilities() ) and it started to work.

Weird turn of events from the weekend. I decided to reorganize all my plugins using the plugins folder like Lazy nvim suggests. I created a file for mason where I setup lsps and another for nvim-cmp. This change broke roslyn.nvim for me again. I suspected it had something to do with the capabilities again, maybe the way lazy vim loads Mason and nvm-cmp the ordering was wrong. As I was debugging I set capabilities to nil and everything started working again. I'm not sure if this is correct? but now my setup looks like this:

require("roslyn").setup({
   on_attach = _G.on_attach(lsp),
   capabilities = nil,
 })
