Consuming a WCF-Service with Xamarin.Android-App

Hello altogether,

With the help of https://code.msdn.microsoft.com/windowsapps/How-to-access-data-from-935e360c, I created successfully a service which reads from database. When testing it with the Windows App as recommended, everything works perfect.

Now I want to consume this service not with Windows-App, but with my Xamarin.Android app. Unfortunately, I am lacking of the ServiceClient-class:

try
{
    ServiceClient client = new ServiceClient();
    IList<Standort> standortListe = await client.QueryAdresseAsync();
}
catch (Exception ex)
{

}

Can anyone maybe tell me if there is something similar in Xamarin.Android and how to be able to consume this service and display the received data (adrList) on e.g. a ListView or (as it is only one row) a TextView or something?

That would really be very kind.

I will share the code of the service, too, maybe it helps a little to understand.

IService.cs

[ServiceContract]
public interface IService
{
    [OperationContract]
    IList<Standort> QueryAdresse();
}

Service.svc.cs:

public class Service1 : IService
{
    public string SqlConStr = "Data Source=[ipadress]\\[instance_name];Initial Catalog=[dbname];user id=[dbusr];password=[dbpw];";

    public IList<Standort> QueryAdresse()
    {
        DataSet ds = new DataSet();
        using (SqlConnection sqlCon = new SqlConnection(SqlConStr))
        {
            try
            {
                sqlCon.Open();
                string sqlStr = "select adrsuche1 from adressen";
                SqlDataAdapter sqlDa = new SqlDataAdapter(sqlStr, sqlCon);
                sqlDa.Fill(ds);
            }
            catch
            {
                return null;
            }
            finally
            {
                sqlCon.Close();
            }
        }

        List<Standort> adrList = new List<Standort>();
        DataTable dt = ds.Tables[0];
        foreach (DataRow dr in dt.Rows)
        {
            adrList.Add(new Standort()
            {
                Adresse = dr["adrsuche1"] as string,
            });
        }

        return adrList;
    }

Thanks in advance for everything,

Best regards
