A practical guide to pattern matching in C#, covering its evolution from C# 7 through C# 10. Topics include constant patterns, discard patterns, variable patterns with when guards, relational patterns, logical operators (and/or/not), tuple patterns, property patterns, nested property patterns, and type patterns. The post highlights how pattern matching improves code expressiveness and how the compiler helps catch unhandled or conflicting cases.
