handling Namensraumänderungen während der Deserialisierung von JSON String

Ich habe 2 Anwendungen, die mit Hilfe eines Redis-Servers miteinander kommunizieren. In meiner ersten Anwendung kann ich serialisieren und de-serialisieren und Objekte des folgenden Typs

   {

Ich kann dies in einer Anwendung serialisieren und de serialisieren, aber wenn ich versuche, dies in einer anderen Anwendung zu de serialisieren, die offensichtlich einen anderen Namensraum hat. und ich bekomme eine Ausnahme

Fehlerauflösungs-Typ in JSON 'System.Collections.Generic.Dictionary`2 [[System.Int32, mscorlib], [OPCMessagingService.Resource, OPCMessagingService]], mscorlib' angegeben. Pfad '$ type', Zeile 1, Position 138.

Ich habe versucht, Folgendes zu tun, während der Json-String in einer anderen Anwendung de-serialisiert wurde, und es funktioniert nicht. Was kann ich sonst tun, um dieses Objekt de-serialisiert zu bekommen?

 public static T GetRedisKeyValue<T>(string key)
    {
        if (key.Trim().Length > 0)
        {
            GetSentinelMaster();
            using (ConnectionMultiplexer redisClient = ConnectionMultiplexer.Connect(GetRedisConfiguraion()))
            {
                IDatabase redisDB = redisClient.GetDatabase(); // Getting database connection
                string temp = redisDB.StringGet(key);
                Type type = typeof(T);
                JObject jsonObject = JObject.Parse(temp);
                jsonObject["$type"] = type.FullName + ", " + type.Assembly.FullName;
               // JsonConvert.DeserializeObject<T>(temp);
                return JsonConvert.DeserializeObject<T>(temp, new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.Objects, TypeNameAssemblyFormat = System.Runtime.Serialization.Formatters.FormatterAssemblyStyle.Full });
            }
        }
        return default(T);
    }

Was kann ich sonst noch tun, um dies zu erreiche
