CliFx is an opinionated, class-first framework for building command-line applications in .NET. It handles argument parsing, command routing, help text generation, and error handling so developers only define commands as classes with attributes.

Use cases

• build a cli application in c#
• parse command-line arguments in dotnet
• generate help text for cli commands automatically
• create nested command hierarchies for a terminal tool
• make a testable console application
• build an aot-compatible command-line tool

When to choose

• you want a complete cli framework rather than just an argument parser
• you prefer declarative class-and-attribute command definitions
• you need auto-generated help, routing, and error handling out of the box
• you target .NET Standard 2.0+ or need Native AOT/trimming support

When to avoid

• you need a low-level argument parser with full manual control
• you're not on the .NET ecosystem
• you dislike opinionated frameworks with implicit conventions
• you object to the project's terms-of-use political statements
