In Windows Phone ShareLinkTask is not Exist for that we are used DataTransferManager.
Try this code it is helpful to you.
public void QuizPostAppLinkToSocialNetworks(ListBox listBox, MenuFlyoutItem selectedItem, string message)
DataTransferManager shareLinkTask = DataTransferManager.GetForCurrentView();
shareLinkTask.DataRequested += delegate(DataTransferManager sender, DataRequestedEventArgs args) { shareLinkTask_DataRequested(sender, args, message,listBox,selectedItem); };
void shareLinkTask_DataRequested(DataTransferManager sender, DataRequestedEventArgs args, string message,ListBox listBox, MenuFlyoutItem selectedItem)
ListBoxItem selectedListBoxItem = listBox.ItemContainerGenerator.ContainerFromItem(selectedItem.DataContext) as ListBoxItem;
string lnk = message;
lnk += "'" + (selectedListBoxItem.Content as QuizList).Name + "', Get the app at \n";
DataRequest request = args.Request;
request.Data.Properties.Title = ResourceHelper.ProjectName + " App";
request.Data.SetWebLink(ResourceHelper.AppMarketplaceWebLink);
request.Data.Properties.Description = lnk;
