+### Resolving Controllers from Unity
+
+By default ASP resolves controllers using built in activator. To enable resolution of controllers from Unity you need to add following line to MVC configuration:
+```C#
+public void ConfigureServices(IServiceCollection services)
+{
+    services.AddMvc()
+            .SetCompatibilityVersion(CompatibilityVersion.Version_xxx) 
+            .AddControllersAsServices(); <-- Add this line
+}
+```
