I.e.: <ListView x:Name=”questionsView” Background=”{StaticResource ApplicationPageBackgroundThemeBrush}”> <ListView.ItemTemplate> <DataTemplate> <Border Background=”BlueViolet”> <Grid HorizontalAlignment=”Stretch” Margin=”0″> <TextBlock Text=”{Binding}” /> <TextBlock HorizontalAlignment=”Right”>16 minutes ago</TextBlock> </Grid> </Border> </DataTemplate> </ListView.ItemTemplate> <ListView.ItemContainerStyle> <Style TargetType=”ListViewItem”> <Setter Property=”HorizontalContentAlignment” Value=”Stretch” /> </Style> </ListView.ItemContainerStyle> </ListView>
You only need to return an awaitable. Task/Task<TResult> is a common choice; Tasks can be created using Task.Run (to execute code on a background thread) or TaskCompletionSource<T> (to wrap an asynchronous event). Read the Task-Based Asynchronous Pattern for more information.
It’s indeed gone: List<T>.ForEach has been removed in Metro style apps. While the method seems simple it has a number of potential problems when the list gets mutated by the method passed to ForEach. Instead it is recommended that you simply use a foreach loop. Wes Haggard | .NET Framework Team (BCL) | http://blogs.msdn.com/b/bclteam/ Very … Read more
Here’s what you can do to retrieve the version in code: using Windows.ApplicationModel; public static string GetAppVersion() { Package package = Package.Current; PackageId packageId = package.Id; PackageVersion version = packageId.Version; return string.Format(“{0}.{1}.{2}.{3}”, version.Major, version.Minor, version.Build, version.Revision); } Reference: http://www.michielpost.nl/PostDetail_67.aspx

SimpleIoc crib sheet: You register all your interfaces and objects in the ViewModelLocator class ViewModelLocator { static ViewModelLocator() { ServiceLocator.SetLocatorProvider(() => SimpleIoc.Default); if (ViewModelBase.IsInDesignModeStatic) { SimpleIoc.Default.Register<IDataService, Design.DesignDataService>(); } else { SimpleIoc.Default.Register<IDataService, DataService>(); } SimpleIoc.Default.Register<MainViewModel>(); SimpleIoc.Default.Register<SecondViewModel>(); } public MainViewModel Main { get { return ServiceLocator.Current.GetInstance<MainViewModel>(); } } } Every object is a singleton by default.

This solved my issue: Windows.ApplicationModel.Core.CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () => { // Your UI update code goes here! } ); Correct way to get the CoreDispatcher in a Windows Store app
Use textContent instead of value to set the button text. Typically the value attribute is used to associate a value with the button when it’s submitted as form data. Note that while it’s possible to set the button text with innerHTML, using textContext should be preferred because it’s more performant and it can prevent cross-site … Read more
My process above still works, but it simply gets around a race condition issue, where Windows Update (yes, oddly enough) is in charge of wiping out “staged packages.” According to Microsoft, the “other fix” – and I still consider this issue to be a bug – is: Cause of the problem: Windows Update (WU) downloads … Read more
