c# - Get with Foreign Keys not Returning data properly -

i trying select rows contact table , return them in wepapi method data not coming properly. can see rows in collection don't deserialize properly. can see why don't know how correct it.

here table structure.

here results of var contacts = db.contacts.asenumerable();

but json deserializes incorrectly causing second contact null.

the second contact nested inside first contacts contact type. problem lies don't know why it's happening or how correct it.

i'm using jsonnetserialization conversions

edit posting json code sections:

public class jsonnetserialization : iserialization {     public string serialize<t>(object o)     {         return jsonconvert.serializeobject((t)o);     }      public object deserialize<t>(stream stream)     {         return jsonconvert.deserializeobject<t>(new streamreader(stream).readtoend());     } }   public class baserepository {     protected iserialization _serializer;     protected object deserialize<t>(stream stream)     {         var retval = _serializer.deserialize<t>(stream);         return retval;     }      protected string serialize<t>(t value)     {         var retval = _serializer.serialize<t>(value);         return retval;     } }  public structuremapregistry() {     for<iserialization>().use<jsonnetserialization>(); }
