title: UWP Tiles - AdaptiveImage AlternateText not showing up
body: <p><strong>Question</strong>: Why my following code for a Tile on windows 10 start menu shows the image, but when I hover over the image it does not show the <a href="https://docs.microsoft.com/en-us/dotnet/api/microsoft.toolkit.uwp.notifications.adaptiveimage.alternatetext?view=win-comm-toolkit-dotnet-stable" rel="nofollow noreferrer">Alternate Text</a>. What I may be missing here, and how can we make it work?</p>
  <p><strong>Code</strong>:</p>
  <pre><code>public void TileTest()
  {
      TileContent content = new TileContent()
      {
          Visual = new TileVisual()
          {
              TileWide = new TileBinding()
              {
  
                  Content = new TileBindingContentAdaptive()
                  {
                      Children =
                      {
                          new AdaptiveGroup()
                          {
                              Children =
                              {
                                  new AdaptiveSubgroup()
                                  {
                                      HintWeight = 2,
                                      Children =
                                      {
                                          new AdaptiveImage()
                                          {
                                              Source = &quot;Images/MyImages/Test.png&quot;,
                                              AlternateText = &quot;Test alternative text&quot;
                                          }
                                      }
                                  }
                              }
                          },
                      }
                  }
              }
          }
      };
  
      TileNotification notification = new TileNotification(content.GetXml());
      TileUpdateManager.CreateTileUpdaterForApplication().Update(notification);
  }
