• Tree-sitter: tree-sitter/tree-sitter-c-sharp
• Language Server: OmniSharp/omnisharp-roslyn

Configuration

The OmniSharp binary can be configured in a Zed settings file with:

{
  "lsp": {
    "omnisharp": {
      "binary": {
        "path": "/path/to/OmniSharp",
        "arguments": ["optional", "additional", "args", "-lsp"]
      }
    }
  }
}

If you want to disable Zed looking for a omnisharp binary, you can set ignore_system_version to true:

{
  "lsp": {
    "omnisharp": {
      "binary": {
        "ignore_system_version": true
      }
    }
  }
}
