System.Runtime.MemoryCache invalidation using Redis PubSub feature.

Install-Package RedisMemoryCacheInvalidation

quick start

First, you have to configure the library, mainly to setup a persistent redis connection and various stuff

  // somewhere in your global.asax/startup.cs
  InvalidationManager.Configure("localhost:6379", new InvalidationSettings());

Redis connection string follow StackExchange.Redis Configuration model

Threre are at least 3 ways to send invalidation messages :

• send an invalidation message via any redis client following the command PUBLISH invalidate onemessagekey
• use InvalidationManager.InvalidateAsync (same as the previous one)
• use keyspace notification (yes, RedisMemoryCacheInvalidation supports it)

Once an invalidation message is intercepted by the library, you can invalidate one or more items at the same time by using InvalidationSettings.InvalidationStrategy

• InvalidationStrategyType.ChangeMonitor => a custom custom change monitor InvalidationManager.CreateChangeMonitor
• InvalidationStrategyType.AutoCacheRemoval => use the automatic MemoryCache removal configured at InvalidationSettings.ConfigureAsync
• InvalidationStrategyType.External => use the callback configured at InvalidationSettings.InvalidationCallback
