## What it is
A Vim plugin that provides IDE-like features for C# development, powered by the OmniSharp-Roslyn server. It offers contextual code completion, go-to-definition, find usages, code actions, and symbol search within Vim or Neovim.

## Use cases
- get intellisense and code completion for C# in Vim
- jump to definition and find usages of C# symbols in Vim
- refactor C# code with code actions from Vim
- find and fix code issues like unused usings in Vim
- search C# symbols interactively with fzf or CtrlP in Vim

## When to choose
- you develop C# in Vim or Neovim and want IDE features without leaving the editor
- you want cross-platform C# tooling on Windows, Linux, or macOS
- you already use completion plugins like coc.nvim, asyncomplete, ncm2, or deoplete

## When to avoid
- you use an editor with native LSP support and prefer a standard language server setup
- you don't write C# or .NET code
- you want a fully self-contained plugin without needing the external OmniSharp-Roslyn server
