C# 7
summary
Walks through concrete C# 7 features with examples and tradeoffs: value tuples as mutable structs that avoid heap allocation for returning multiple values (min/max example), element names persisted in metadata, and a NodaTime extension showing deconstruct for year/month/day and constructor field assignment. Demonstrates pattern matching (type, constant, var) with switch/when guards and gotchas like int 5 vs 5L, local functions for clearer validation and efficient captured-state code, and valueTask for ASP.NET Core async optimization. Mentions throw as expression and readable numeric literals with underscores.
