Design patterns allow you to reuse critical code patterns. This can help you build better code and efficiently tackle real-world design problems. In this course, follow developer and technologist Reynald Adolphe as he explores some of the Gang of Four design patterns, and covers some lesser-known patterns for C# programmers. Reynald covers a creational pattern—Builder—and then dives into structural patterns like Adapter and Composite.
