Entity Framework Model & WCF (Saving a Record)

I  am trying to convert JsonData into the object to save it into the database table using Entity framework model using the attached code. but ends up with the following error:

The type 'XXX"  cannot be serialized to JSON because its IsReference setting is 'True'. The JSON format does not support references because there is no standardized format for representing references. To enable serialization, disable the IsReference setting on the type or an appropriate parent class of the type.

The tableNameListData is:
String tableNameListData ="\"badges\":\"1\",\"notifications\":\"1\",\"sounds\":\"1\"}";

I am calling the attached code function in the following way:

  public string AddToTableNameList(string tableNameListData)
        {
            tableName ed = Deserialize<tablename>(tableNameListData); [Here isreference error comes]
            ----
            ---
        }

 
Please help!
public static T Deserialize<T>(string json) //
        {
            T obj = Activator.CreateInstance<T>();
            MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json));
            DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
            obj = (T)serializer.ReadObject(ms);
            ms.Close();
            return obj;
        }

In wcf method I wrote:
tableName objw = new tableName();    
JavaScriptSerializer serializer = new JavaScriptSerializer();  
objw = serializer.Deserialize<tableName>(tableJsonData);    


and i called it this way i.e modified the input data as follows:

String tableJsonData="{\"badges\":\"true\",\"notifications\":\"true\",\"sounds\":\"true\"}";

so if it is having corresponding int in the database table then the value say
\"id\":\"value\"
value should be integer e.g 4 or 5 etc. and not like 'din'

this way I was able to solve the issue.

also note true is not equal to 1 in c# so we need to write true only.
