Change your habits: Modern techniques for modern C#
summary
Demonstrates concrete C# practices: using tuple assignments for swaps and concise equality/constructors, declaring read-only structs and read-only members to let the compiler enforce immutability, and enabling nullable reference types plus the ?? throw discard pattern to replace verbose null checks. Builds a toll-calculator with a pattern-matching switch that shrinks a 50-line if/else into six concise rows, and shows DateTime.AddYears to avoid a leap-year bug — all working code-level fixes and refactorings.
