+# EF Query Cache Control
+
+EF+ Cache is very flexible and lets you have full control over the cache.
+
+You can use your own cache:
+-core
+{% include template-example.html %} 
+```csharp
+QueryCacheManager.Cache = new MemoryCache(new MemoryCacheOptions());
+context.Customers.FromCache().ToList();
+
+```
+[Try it](https://dotnetfiddle.net/6ISVBT)
+
+You can set default policy
+
+{% include template-example.html %} 
+```csharp
+
+var options = new MemoryCacheEntryOptions() { SlidingExpiration = TimeSpan.FromHours(2)};
+QueryCacheManager.DefaultMemoryCacheEntryOptions = options;
+context.Customers.FromCache().ToList();
+
+```
