Explain CLR & types in the context of SignalR Real-Time.

Short answer: The CLR loads assemblies, manages memory (GC), and JIT-compiles IL to native code. Value types live on the stack or inline in objects; reference types live on the heap with GC tracking.

Real-world example (ShopNest)

In a ShopNest .NET service, explain the idea in one sentence, show where it sits in the request/data flow, then give one production trade-off.

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.
