coc-csharp

C# extension for coc.nvim which uses Roslyn language server.

Almost all the code is taken from vscode-csharp with some modifications to work with coc.nvim.

Note: This extension is still in development and may not work as expected. And I'm a newbie in TypeScript (actually, it's my first time to write TypeScript), so the code may not be the best. Any PRs are welcome.

Install

1. Install coc.nvim
2. Install .NET SDK
3. Install Roslyn language server (Optional. If you don't specify the path via csharp.server.path, the extension will try to download the language server automatically)
   1. Navigate to this feed, search for Microsoft.CodeAnalysis.LanguageServer and download the version matching your OS and architecture.
   2. Unzip the downloaded .nupkg
   3. (Optional) Copy the contents of <zip_root>/content/LanguageServer/<your_arch> to a directory of your choice
   4. Check if it's working by running dotnet <root_dir>/content/LanguageServer/<your_arch>/Microsoft.CodeAnalysis.LanguageServer.dll --version
   5. Set csharp.server.path to the path of the <root_dir>/content/LanguageServer/<your_arch>/Microsoft.CodeAnalysis.LanguageServer.dll in your coc-settings.json
4. Install the extension by running :CocInstall @tcx4c70/coc-csharp
