CommandLineParser is a C# library for parsing command line arguments in .NET applications, offering a getopt-style API for defining options, switches, and verb commands. It includes automatic help screen generation, syntax error reporting, and optional F# support.

Use cases

• parse command line arguments in a .NET console app
• define git-style verb commands like 'commit' and 'add'
• auto-generate a customizable help screen for a CLI tool
• report syntax errors to users of a command line utility
• support mutually exclusive options and default values in a CLI
• build a cross-platform CLI tool with .NET Core or .NET Standard

When to choose

• you're building a .NET or .NET Core console application that needs robust argument parsing
• you want standardized *nix getopt-style parsing with minimal dependencies
• you need automatic, customizable help text and error reporting
• you want verb-command support similar to git's CLI structure

When to avoid

• you're not working in the .NET ecosystem
• you need a full CLI framework with prompts, colors, or interactive features rather than pure parsing
• your project requires a very lightweight or zero-dependency solution beyond what base libraries provide
