    2.     x:Class="ShareAttachment.MainPage"  
    3.     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"  
    4.     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"  
    5.     xmlns:local="using:ShareAttachment"  
    6.     xmlns:d="http://schemas.microsoft.com/expression/blend/2008"  
    7.     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"  
    8.     mc:Ignorable="d">  
    9.   
    10.     <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">  
    11.         <Button x:Name="btn_Share" Content="Share Attachment" HorizontalAlignment="Left" Margin="377,231,0,0" VerticalAlignment="Top" Click="btn_Share_Click"/>  
    12.   
    13.     </Grid>  
    14. </Page>

  3. using System.IO;  
  4. using System.Linq;  
  5. using System.Runtime.InteropServices.WindowsRuntime;  
  6. using Windows.ApplicationModel.DataTransfer;  
  7. using Windows.Foundation;  
  8. using Windows.Foundation.Collections;  
  9. using Windows.UI.Xaml;  
  10. using Windows.UI.Xaml.Controls;  
  11. using Windows.UI.Xaml.Controls.Primitives;  
  12. using Windows.UI.Xaml.Data;  
  13. using Windows.UI.Xaml.Input;  
  14. using Windows.UI.Xaml.Media;  
  15. using Windows.UI.Xaml.Navigation;  
  16.   
  17. namespace ShareAttachment  
  18. {  
  19.     public sealed partial class MainPage : Page  
  20.     {  
  21.         public MainPage()  
  22.         {  
  23.             this.InitializeComponent();  
  24.             var dtm = Windows.ApplicationModel.DataTransfer.DataTransferManager.GetForCurrentView();  
  25.             dtm.DataRequested += Dtm_DataRequested;  
  26.         }  
  27.   
  28.         private async void Dtm_DataRequested(Windows.ApplicationModel.DataTransfer.DataTransferManager sender, Windows.ApplicationModel.DataTransfer.DataRequestedEventArgs args)  
  29.         {  
  30.             DataPackage dataToShare = args.Request.Data;  
  31.             dataToShare.Properties.Title = "Attachment Sharing Application";  
  32.             dataToShare.Properties.Description = "Attachment Sharing Application that share images";  
  33.   
  34.             var storageFile = await Windows.ApplicationModel.Package.Current.InstalledLocation.GetFileAsync("Assets\\abc.jpg");  
  35.             var imageStream = Windows.Storage.Streams.RandomAccessStreamReference.CreateFromFile(storageFile);  
  36.             dataToShare.SetBitmap(imageStream);  
  37.         }  
  38.   
  39.         private void btn_Share_Click(object sender, RoutedEventArgs e)  
  40.         {  
  41.             Windows.ApplicationModel.DataTransfer.DataTransferManager.ShowShareUI();  
  42.         }  
  43.     }  
  44. }  
Step 5:

Run the application, click the Share Attachment button and you see a Share UI open in the right side of app.

Click on Mail and you see an email compose with an image attached.
