DataCacheFactory factory = new DataCacheFactory(); DataCache cache = factory.GetCache(“MyCache”); cache.Add(“UserId-123”, “JohnDoe”); string user = cache.Get(“UserId-123”) as string; | Factor | Recommendation | |--------|----------------| | Serialization | Use binary serialization for complex objects. NET native serialization is faster than XML. | | Local Cache | Enable for read-heavy, rarely-changed data. Set sync policy to TimeoutBased or NotificationBased . | | Eviction Policy | LRU (Least Recently Used) for general caches. FIFO for sequential access patterns. | | Cluster Size | Minimum 3 cache hosts for production (for quorum and redundancy). | | Backup Count | Set to 1 for high availability (each partition has one backup). | Migration Paths and Modern Alternatives Microsoft has officially shifted away from AppFabric caching. Here is the current landscape:
| AppFabric Component | Modern Replacement | |---------------------|--------------------| | Caching Service | (on-prem: Redis on Windows/Linux, Cloud: Azure Cache for Redis) | | ASP.NET Session State Provider | Azure Cache for Redis Session State Provider or Database-backed sessions | | Workflow Hosting & Persistence | Azure Logic Apps or Durable Functions or Workflow Core (open source) | | WCF Hosting Management | Transition to gRPC or ASP.NET Core Web APIs | appfabric
