Handling resource cleanup (e.g. DbContext disposal)?

Short answer: Use DI to manage lifecycle of DbContext as Scoped. Avoid manual disposal; rely on DI container. Dispose IDisposable objects promptly when created manually. Use using statements for short-lived resources.

Real-world example (ShopNest)

ShopNest registers AppDbContext as Scoped and IMemoryCache as Singleton. Putting DbContext in a Singleton causes threading bugs.

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.
