using WeatherDataWPF.ServiceReference1;

namespace WeatherDataWPF

public partial class MainWindow : Window

private ServiceReference1.IService1 client = new ServiceReference1.Service1Client();

      public MainWindow()
      {
          InitializeComponent();
          this.fromPicker.SelectedDate = new DateTime(2013, 1, 1);

      private void Button_Click(object sender, RoutedEventArgs e)

Hi @lookforme-8548,
You only posted the code, but did not indicate your needs. Is there an error message in the code?
Best regards,
Lan Huang
