I'm using AppFabric version 1.1. This issue only happen on debug mode.

To simplify my code,  basically I have four Self Tracking Entity (STE) models. 

    [DataContract]
    public class Model_Root
    {
        [DataMember]
        public int Id { get; set; }

        //Navigation Property
        [DataMember]
        private TrackableCollection<Model_A> Model_A_Collection { get; set; }

        [DataMember]
        private TrackableCollection<Model_B> Model_B_Collection { get; set; }


    }

    [DataContract]
    public class Model_A
    {
        [DataMember]
        public int Model_A_Id { get; set; }

        //Navigation Property
        [DataMember]
        public Model_Root ModelRoot { get; set; }

        [DataMember]
        public TrackableCollection<Model_A_B> Model_A_B { get; set; }
    }

    [DataContract]
    public class Model_B
    {
        [DataMember]
        public int Model_B_Id { get; set; }

        //Navigation Property
        [DataMember]
        public Model_Root ModelRoot { get; set; }

        [DataMember]
        public TrackableCollection<Model_A_B> Model_A_B { get; set; }
    }

    [DataContract]
    public class Model_A_B
    {
        [DataMember]
        public int Model_A_Id { get; set; }

        [DataMember]
        public int Model_B_Id { get; set; }

        //Navigation Property
        [DataMember]
        public Model_A Model_A { get; set; }

        [DataMember]
        public Model_B Model_B { get; set; }
    }

For app fabric, the class as below

 

 public static class CacheManager
    {
        private static DataCache _dataCache;

        static CacheManager()
        {
            var cahceFactory = new DataCacheFactory();
            _dataCache = cahceFactory.GetCache("Development_Cache_Name");
        }


        public static object Get(Model_Root modelRoot)
        {
            var key = String.Format("Model_Root_{0}", modelRoot.Id);
            return _dataCache.Get(key, "Model_Root");
        }
    }
