## What it is
A comprehensive C# library of 33 design patterns with 73 moderately realistic examples, covering Gang of Four patterns and lesser-known ones. It is an educational resource for learning when and how to apply creational, structural, and behavioral design patterns.

## Use cases
- learn design patterns in c#
- see real-world examples of gof patterns
- understand creational structural and behavioral patterns
- study oop architecture patterns in dotnet
- find when a design pattern becomes an antipattern
- reference implementation of adapter or abstract factory in c#

## When to choose
- you are learning or teaching design patterns in C#/.NET
- you want runnable, moderately realistic example code for each pattern
- you need a reference covering both common and lesser-known patterns

## When to avoid
- you need a production-ready pattern library to drop into an application
- you work outside the .NET/C# ecosystem
- you need a formally licensed dependency (no license is specified)

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, documentation
- domain: developer-tools, tutorials, programming-languages
- platform: dotnet, cross-platform
- tags: design-patterns, gof-patterns, csharp, oop, software-architecture, educational-examples
