AsyncMemoryCache 1.0.2

AsyncMemoryCache

A highly configurable cache that aims to improve upon IMemoryCache without relying on it as its backing store.

• Lightweight
• Strongly typed
• Configurable eviction behavior
• Configurable lifetime for cache entries
• Lazy construction of cache object
• Supports asynchronous factories
• Automatic disposal of expired cache entries
• Integration with Microsoft.Extensions.DependencyInjection
• Integration with Microsoft.Extensions.Logging

Usage

using AsyncMemoryCache;

ILoggerFactory loggerFactory = ...;

var cacheLogger = loggerFactory.CreateLogger<AsyncMemoryCache<string, TheClassToCache>>();

var cacheConfig = new AsyncMemoryCacheConfiguration<string, TheClassToCache>
{
	EvictionBehavior = EvictionBehavior.Default // new DefaultEvictionBehavior(TimeProvider.System, TimeSpan.FromSeconds(45))
};

var cache = new AsyncMemoryCache<string, TheClassToCache>(cacheConfig, cacheLogger); // Logger is optional

// The factory is started here, will not block
var cacheEntity = cache.Add("theKey", async () =>
{
	var createdObject = await ...;
	await Task.Delay(1000);
	return createdObject;
})
.WithSlidingExpiration(TimeSpan.FromHours(12));

// Will block here until the object is created
var theCachedObject = await cache["theKey"];
