<Window x:Class="YourNamespace.YourWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Your Window" WindowStyle="None">
    <!-- Window Content Here -->
</Window>

public partial class YourWindow : Window
{
    public YourWindow()
    {
        InitializeComponent();
    }

    private void Window_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
    {
        DragMove();
    }

    private void CloseButton_Click(object sender, RoutedEventArgs e)
    {
        Close();
    }
}

<Window x:Class="YourNamespace.YourWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Your Window" WindowStyle="None">
    <Grid>
        <!-- Window Content Here -->
        <Button x:Name="CloseButton" Content="X" HorizontalAlignment="Right" VerticalAlignment="Top" Margin="0,5,5,0" Click="CloseButton_Click"/>
    </Grid>
</Window>
