When you have created a new WPF application you should have a  xaml file and a  cs file  These represent your main window  Create an additional  xaml file and  cs file to represent your sub window   MainWindow xaml   lt Window x Class  WpfApplication2 MainWindow      xmlns  http   schemas microsoft com winfx 2006 xaml presentation      xmlns x  http   schemas microsoft com winfx 2006 xaml      Title  MainWindow  Height  350  Width  525  gt       lt Grid gt           lt Button Content  Open Window  Click  ButtonClicked  Height  25  HorizontalAlignment  Left  Margin  379 264 0 0  Name  button1  VerticalAlignment  Top  Width  100    gt       lt  Grid gt   lt  Window gt    MainWindow xaml cs  public partial class MainWindow   Window       public MainWindow                 InitializeComponent               private void ButtonClicked object sender  RoutedEventArgs e                SubWindow subWindow   new SubWindow            subWindow Show              Then add whatever additional code you need to these classes   SubWindow xaml SubWindow xaml cs

In WPF we have a couple of options by using the Show   and ShowDialog   methods   Well  if you want to close the opened window when a new window gets open then you can use the Show   method   Window1 win1   new Window1    win1 Show    win1 Close      ShowDialog   also opens a window  but in this case you can not close your previously opened window

You can create a button in window1 and double click on it  It will create a new click handler  where inside you can write something like this   var window2   new Window2    window2 Show

This helped me  The Owner method basically ties the window to another window in case you want extra windows with the same ones    LoadingScreen lc   new LoadingScreen    lc Owner   this  lc Show      Consider this as well    this WindowState   WindowState Normal  this Activate

You will need to create an instance of a new window like so   var window2   new Window2      Once you have the instance you can use the Show   or ShowDialog   method depending on what you want to do   window2 Show      or  var result   window2 ShowDialog      ShowDialog   will return a Nullable lt bool gt  if you need that
