Deploy self-contained trimmed builds for smaller binaries. Example for build optimization: dotnet publish -c Release /p:PublishTrimmed=true /p:ReadyToRun=true 🔐 10. What is Data Protection in ASP.NET Core? Follow :

Short answer: ASP.NET Core Data Protection API provides secure cryptographic APIs for: Encrypting cookies and tokens Protecting form data Persisting secure keys (across app restarts) Setup: builder.Services.AddDataProtection() .PersistKeysToFileSystem(new DirectoryInfo(@"c:\keys")) .SetApplicationName("MyApp"); You can use it directly: var protector =………… _provider.CreateProtector("MyPurpose"); var encrypted =…

Explain a bit more

protector.Protect("secret-data"); var decrypted = protector.Unprotect(encrypted); ✅ Data Protection is the backbone for: Cookie Authentication CSRF Tokens TempData encryption 🧠 Summary Concept Description Best For In-memory caching Stores data in server memory Single-server or dev Distributed caching Shared cache (Redis, SQL) Scalable apps Response caching Caches HTTP responses Public/static data Follow : Output caching (.NET 8) Advanced, user-aware caching Dynamic APIs Response compression Gzip/Brotli for responses Large payloads Async/await Non-blocking I/O High concurrency Startup optimization Faster app boot… ASP.NET Core Data……

Real-world example (ShopNest)

ShopNest admin screens use MVC: controller loads data, Razor view renders HTML, Tag Helpers build forms safely.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
