    Here is a snippet of my test code:

    private PendingListViewModel _vm;
            public void Setup()
                var view = Mock.Create<IPendingListView>();
                var repository = Mock.Create<ISubmissionRepository>();
                repository.Arrange(x => x.GetPendingSubmissions()).Returns(GetSubmissionSet());
                var subscribedEvent = Mock.Create<RefreshPendingSubmissions>();
                subscribedEvent.Arrange(x => x.Subscribe(Arg.IsAny<Action<string>>())).DoNothing();
                var events = Mock.Create<IEventAggregator>();
                events.Arrange(x => x.GetEvent<RefreshPendingSubmissions>()).Returns(subscribedEvent);
                _vm = new PendingListViewModel(view, repository, events);
            public void ExecuteSortByCountyCommand_CollectionShouldContainOneSortDescriptor()
                Assert.IsTrue(_vm.SubmissionsCollection.SortDescriptions.Count == 1);

    When I do this I get an exception:

    System.IO.FileLoadException: System.IO.FileLoadException: Could not load file or assembly 'Telerik.JustMock_fe91bf8a4e2f4132a3849f92ab689d67, Version=2012.3.1025.4, Culture=neutral, PublicKeyToken=null' or one of its dependencies. A strongly-named assembly is required. (Exception from HRESULT: 0x80131044).
        at Microsoft.Practices.Prism.Events.CompositePresentationEvent`1.Subscribe(Action`1 action)
       at Complaints.Modules.Web.ViewModels.PendingListViewModel..ctor(IPendingListView view, ISubmissionRepository subRepository, IEventAggregator events) in PendingListViewModel.cs: line 73

    If I remove the code that creates and arranges subscribedEvent and leave the mocked event aggregator alone (just create, no arranging), then the same line of code returns a NullReferenceException.

    The problem line of code is :
    _events.GetEvent<RefreshPendingSubmissions>().Subscribe(a => OnRefresh());

    in the constructor of my Class under test.

    I had the same issues when I used a Mocking Container, so I switched to creating all the mocks individually, but it's still not working.

    What am I doing wrong?
