asp.net mvc 4 - Unity.MVC4 Doesn't Dispose() -

i've installed nuget unity.mvc4 package http://nuget.org/packages/unity.mvc4/ , have hooked same if using unity.mvc3 package.

my dependencies getting resolved correctly, when using hierarchicallifetimemanager, object's dispose() method not called @ end of request.

i've set simple project using unity.mvc3 , unity.mvc4, exact same bootstrapper.cs code in both projects. on mvc3 version, dispose() called; on mvc4 version, not.

i'm registering type so

            container.registertype<itest, test>(new hierarchicallifetimemanager()); 

with simple test class

    public interface itest {     void foo(); }  public class test : idisposable, itest {     public test()     {      }      public void foo()     {      }      public void dispose()     {      } } 

i don't think i'm doing incorrectly, there appears bug in unity.mvc4 package.

if using package, i'm curious how got work.

the best solution issue upgrade unity3 , install unity bootstrapper asp.net mvc package. bootstrapper package includes perrequestlifetimemanager should used in place of hierarchicallifetimemanager. once integration complete, dispose() called @ end of every http request expected.

note newest unity documentation suggests perrequestlifetimemanager should not used @ unless absolutely necessary. (i believe, however, still needed in cases - example, want share dbcontext across objects used during single request.)

with solution, unity.mvc4 no longer needed , can uninstalled.
