Answer
Use:
- IMemoryCache for local cache
- Redis for distributed cache
Cache expensive queries and invalidate on updates.
Quick Answer
Cache DB queries: IMemoryCache for single-server in-process cache. IDistributedCache (Redis) for multi-server. Pattern: check cache first (cache.TryGetValue(key, out var result)), on miss query DB and cache result with TTL, on data change invalidate cache. EF Core Second Level Cache NuGet packages automate this. Cache reference data (countries, categories) aggressively; user-specific data with short TTL or not at all.
