## What it is
Cocona is a micro-framework for building .NET console applications with an ASP.NET Core-like minimal API style. It provides UNIX-style command-line option parsing, built-in help, shell completion, and native support for DI, logging, and configuration.

## Use cases
- build a cli tool in c#
- create console application with subcommands on .net
- parse command-line options like unix tools in dotnet
- add shell completion to a dotnet cli app
- build multi-command console app with dependency injection
- generate help text for a command-line tool

## When to choose
- you want an ASP.NET Core-like development experience for console apps
- you need getopt-style option semantics and sub-commands
- you want built-in help, validation, and bash/zsh completion out of the box
- you want DI, logging, and configuration integrated into a CLI

## When to avoid
- you are not on the .NET platform
- you need a zero-dependency minimal CLI parser (though Cocona.Lite exists)
- you only need simple argument parsing without framework features
- the project's release cadence suggests limited recent activity for critical needs

## Facets
- artifact type: framework
