+# EF Query Cache Control
+
+EF+ Cache is very flexible and lets you have full control over the cache.
+
+You can use your own cache:
+
+{% include template-example.html %} 
+```csharp
+
+// EF5 | EF6 (Cache must inherit from Sytem.Runtime.Caching.ObjectCache)
+QueryCacheManager.Cache = MemoryCache.Default;
+
+
+```
+[Try it in EF6](https://dotnetfiddle.net/mIhcff) | [Try it in EF Core](https://dotnetfiddle.net/6ISVBT)
+
+You can set default policy
+
+{% include template-example.html %} 
+```csharp
+
+// (EF5 | EF6) The query is cached for 2 hours of inactivity
+var options = new CacheItemPolicy() { SlidingExpiration = TimeSpan.FromHours(2)};
+QueryCacheManager.DefaultCacheItemPolicy = options;
+
+// (EF7) The query is cached for 2 hours of inactivity
+var options = new MemoryCacheEntryOptions() { SlidingExpiration = TimeSpan.FromHours(2)};
+QueryCacheManager.DefaultMemoryCacheEntryOptions = options;
+
+```
