  • Second Level Cache for Entity Framework 6.1

    Second Level Cache for Entity Framework 6.1

    Entity Framework does not currently support caching of query results. A sample EF Caching provider is available for Entity Framework version 5 and earlier but due to changes to the provider model this sample provider does not work with Entity Framework 6 and newer. This project is filling the gap by enabling caching of query results for Entity Framework 6.1 applications. https://efcache.codeplex.com/

    How to get it

    You can get it from NuGet - just install the EntityFramework.Cache NuGet package

    How to use it

    The project uses a combination of a wrapping provider and a transaction interceptor. A simple InMemoryCache is included in the project. To use it you need first configure EF using code based configuration. Here is an example of how such a configuration looks like.

    public class Configuration : DbConfiguration
    {
      public Configuration()
      {
        var transactionHandler = new CacheTransactionHandler(new InMemoryCache());
    
        AddInterceptor(transactionHandler);
    
        var cachingPolicy = new CachingPolicy();
    
        Loaded +=
          (sender, args) => args.ReplaceService<DbProviderServices>(
            (s, _) => new CachingProviderServices(s, transactionHandler, 
              cachingPolicy));
      }
    }
