Returning Custom Class from WCF Method? - wcf

Question

There are so many question about that but there is no solution for my problem. I want to return a custom class which has datacontract key and it's members have datamember key. I am getting this error while I testing it;
When I call it from my windows phone application, it returns "The remote server not found"
It returns not found but it runs methods that return types are void, bool, list.

BaseModel Login(string userName, string password);
[DataContract]
public class UserModel
{
private int userID;
[DataMember]
public int UserID
{
get { return userID; }
set { userID = value; }
}
private string userName;
[DataMember]
public string UserName
{
get { return userName; }
set { userName = value; }
}
private string password;
[DataMember]
public string Password
{
get { return password; }
set { password = value; }
}
private string email;
[DataMember]
public string Email
{
get { return email; }
set { email = value; }

}
private DateTime birthDate;

get { return registrationType; }
set { registrationType = value; }
}
private string registeredDeviceType;
[DataMember]

}
[DataContract]
public class BaseModel
{
private string errorMessage;
[DataMember]
public string ErrorMessage
{
get { return errorMessage; }
set { errorMessage = value; }
}
private string informationMessage;
[DataMember]
public string InformationMessage
{

}
private object returnObject;
[DataMember]
public object ReturnObject
{
get { return returnObject; }
set { returnObject = value; }
}
private bool isSucceed;
[DataMember]
public bool IsSucceed
{
get { return isSucceed; }
set { isSucceed = value; }
}
}
And the method is;
public BaseModel Login(string userName, string password)
{
using (SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["conStr"].ConnectionString))
{
connection.Open();
using (SqlCommand command = new SqlCommand("SELECT * FROM UserBaseInformations WITH (NOLOCK) Where UserName=#userName", connection))
{
command.Parameters.Add(new SqlParameter("#userName", userName));
SqlDataAdapter adapter = new SqlDataAdapter();
adapter.SelectCommand = command;
DataTable dt = new DataTable();
adapter.Fill(dt);
DataSet ds = new DataSet();
ds.Tables.Add(dt);
connection.Close();
if (dt.Rows.Count == 0)
return new BaseModel() { IsSucceed = false, ErrorMessage = "Geçersiz bir kullanıcı adı girdiniz." };
else if (!dt.Rows[0]["Password"].ToString().Equals(password))
return new BaseModel() { IsSucceed = false, ErrorMessage = "Şifrenizi yanlış girdiniz." };
else
return new BaseModel()
{
IsSucceed = true,
ReturnObject = new UserModel()
{
Email = dt.Rows[0]["Email"].ToString(),
Password = dt.Rows[0]["Password"].ToString(),
UserID = (int)dt.Rows[0]["UserID"],
UserName = dt.Rows[0]["UserName"].ToString(),
SecurityQuestionID = (int)dt.Rows[0]["SecurityQuestionID"],
SecurityQuestionAnswer = dt.Rows[0]["SecurityQuestionAnswer"].ToString()
}
};
}
}
}

I have found solution.
Returning an object type can be problem in WCF so I changed it to a base class for returning my classes and added KnownType attribute to BaseModel.
