'nullable' enable – Unlock the Power of C# Nullability
summary
Explains that C# nullable reference types give only design‑ and compile‑time warnings, not runtime safety, and uses flow analysis to surface issues; shows practical migration patterns: enable nullable for new projects or convert file‑by‑file starting with DTOs and low‑dependency models; demonstrates tools like Rider/ReSharper automatic migrations, value tracking and JetBrains→C# annotation conversion; warns that EF Core schema changes when nullability flips and calls the null forgiving operator an anti‑pattern.
