This plugin adds support for the new Roslyn-based C# language server introduced in the vscode C# extension.

Requires Neovim 0.10

You need to install the language server yourself. I did this by installing C# dev kit on vscode. I then checked htop and found the .dll file that was ran. Move the entire directory with all the binaries to ~/.local/share/nvim/roslyn. The path to the dll that this plugin runs is: ~/.local/share/nvim/roslyn/Microsoft.CodeAnalysis.LanguageServer.dll

Install seblj/roslyn.nvim using your plugin manager.

require("roslyn").setup({
    -- Optional. Will use `vim.lsp.protocol.make_client_capabilities()`,
    -- and it will also try to merge that with `nvim-cmp` LSP capabilities
    capabilities = nil,
})

1. The plugin will look for a .sln file in parent directories until it finds one. Make sure to have a .sln file somewhere in a parent dir.
2. If it only finds one .sln file, it will use that to start the server. If it finds multiple, you have to run CSTarget to choose which target you want to use.
3. You'll see two notifications if everything goes well. The first one will say Roslyn client initialized for target <target>, which means the server is running, but it will just start indexing your sln. The second one will say Roslyn project initialization complete, it means that the server indexed your sln, only after you see the second notification will the go to definition and other lsp features be available.

Please note that some features from the vscode extension might not be supported by this plugin.
