Blended Cache Framework for .net

Basic Principles:

• 3 layers of caching:
  • Context (Thread based)
  • Volatile (in memory)
  • LongTerm (out of process)
• Wraps up interaction of 3 layers, back filling. eg found in longTerm, put in context, volatile
• Provides flush mode support for forcing refreshes at various layers.
• Allows type load configuration to auto-load items.
• LongTerm supports Refresh and Absolute expiration time. Also background refresh support with TypeLoadConfig
• LongTerm supports Database down Func<bool> parameter to by pass expiration and keep system running.
• LongTerm ideal permanent distributed cacheStore such as memcached, azure, etc.

Sample Context and Volatile for a website.

var contextCache = new HttpContextCache(); // IContextCache
var volatileCache = new RuntimeMemoryCachingVolatileCache();
var configuration = new BlendedCacheConfiguration();

//fancy ioc stuff here.
return new BlendedCache(contextCache, volatileCache, NullLongTermCache.NullInstance, configuration);

NuGet auto-download is required to be configured to supply any third-parties.

1. Tools -> Options -> Package Manager
2. Check the box that says "Allow NuGet to download missing packages during build"
