    Method 1: Set trigger for the Popup using BooleanAnimationUsingKeyFrames.

     <Popup  HorizontalAlignment="Left" VerticalAlignment="Top" Width="200" Height="200" >  
                                <EventTrigger RoutedEvent="MouseMove">  
                                            <BooleanAnimationUsingKeyFrames Duration="0:0:3" Storyboard.TargetProperty="IsOpen">  
                                                    <DiscreteBooleanKeyFrame Value="False" KeyTime="0:0:3"/>  
                            <TextBlock Background="LightBlue" > This is popup text</TextBlock>  

    Method 2: You can add Opened event for your Popup and set a Timer for it:
    The code for the xaml:

            <Button HorizontalAlignment="Left" Click="DisplayPopup" Height="200"  Width="150" Margin="20,10,0,0">  
                    <TextBlock>Display Your Popup Text</TextBlock>  
                    <Popup Name="myPopup" StaysOpen="True" Opened="myPopup_Opened" >  
                        <TextBlock Name="myPopupText"  Background="LightBlue" Foreground="Blue">  
                              Popup Text  

    The code to close it in cs:

    private void DisplayPopup(object sender, RoutedEventArgs e)  
                this.myPopup.IsOpen = true;  
            private void myPopup_Opened(object sender, EventArgs e)  
            private void StartCloseTimer()  
                DispatcherTimer timer = new DispatcherTimer();  
                timer.Interval = TimeSpan.FromSeconds(3d);  
                timer.Tick += TimerTick;  
            private void TimerTick(object sender, EventArgs e)  
                DispatcherTimer timer = (DispatcherTimer)sender;  
                timer.Tick -= TimerTick;  
                this.myPopup.IsOpen = false;

    You can see for example : WPF: How to auto close a popup

    (BTW, you're talking about WPF but you set a tag windows-uwp-runtime...)
