    I have this kind of test situation I need Guid list to be send with ReturnsCollection 

            public void GetCodedObjectsClients_WithServiceArea()
                // Arrange
                KAPRole role = CreateDataRole();

                //Create test worker
                OHPClientWorker clientWorker = new OHPClientWorker(Entities);
                Guid MyGuidi = new Guid("ccae2079-2ebc-4200-879d-866fc82e6afa");
                Guid MyGuidi2 = new Guid("ccae2079-3ebc-4200-879d-866fc82e6afa");            
                IEnumerable<Guid> guids = new List<Guid> { MyGuidi, MyGuidi2 };

                // Create mock data
                Mock.Arrange(() => clientWorker.ServiceAreaWorker.GetServiceAreaUserGuids(Arg.IsAny<long>())).ReturnsCollection(guids);

    But in code to test the Guid list contains only guids 00000 0000 00000 00000 .... So guid was changed from ccae2079-2ebc-4200-879d-866fc82e6afa"  to 00000 0000 00000 0000  Why

     public ICollection<OHPClientWithCodedObject> GetCodedObjectsClients(ICollection<long> objectIDs, ICollection<KAPRole> roles, long serviceAreaID)
                //Users with rights granted through servicearea
                ICollection<Guid> userGuids = ServiceAreaWorker.GetServiceAreaUserGuids(serviceAreaID);
    userGuids  does not contain anymore real Guids

    Any Idea why ReturnsCollection  chages Guids

    Hi Ari,
    Thanks again for reporting the issue. However, I wrote the following test and it worked as per expectation.
    public void ShouldAssertReturnsCollectonOnGuid()
        var client = Mock.Create<OHPClientWorker>();
        Guid MyGuidi = new Guid("ccae2079-2ebc-4200-879d-866fc82e6afa");
        Guid MyGuidi2 = new Guid("ccae2079-3ebc-4200-879d-866fc82e6afa");
        IEnumerable<Guid> guids = new List<Guid> { MyGuidi, MyGuidi2 };
        // Create mock data
        Mock.Arrange(() => client.ServiceAreaWorker.GetServiceAreaUserGuids(Arg.IsAny<long>())).ReturnsCollection(guids);
        ICollection<Guid> userGuids = client.ServiceAreaWorker.GetServiceAreaUserGuids(10);
        Assert.AreEqual(MyGuidi, userGuids.First());
        Assert.AreEqual(MyGuidi2, userGuids.Last());

    Here I used the latest version of the product and I am attaching the sample project to let you have a look. Generally, it should not override any values unless specified. One issue could be that it is creating a default valued object for ServiceAreaWorker class which is not initialized by ReturnsCollection properly. In that regard, I would request you to try the latest SP1 build released yesterday.
