A .NET library for building command line applications, providing argument parsing, option validation, help text generation, and interactive console prompts. It supports both an attribute-based API and a builder-pattern API for defining commands, options, and subcommands.

Use cases

• parse command line arguments in a .NET console app
• build a CLI tool with subcommands in C#
• generate help text automatically for command line options
• validate required options and argument ranges in a CLI
• prompt for passwords and interactive console input
• define CLI options using C# attributes

When to choose

• you are writing a .NET/C# command line application and want mature argument parsing
• you want declarative option definitions via attributes with validation
• you need automatic help text generation and interactive prompts
• you want a well-documented, widely used alternative to System.CommandLine

When to avoid

• you are not on the .NET platform
• you need a full CLI framework with shell completion or config file loading out of the box
• you prefer System.CommandLine or Spectre.Console.Cli ecosystems
