Windows apps written in managed languages still enjoy the Microsoft. NET Framework, which itself is only a collection of interfaces, base classes and helper methods. The subset of the full. NET Core. Supplementing this, the majority of the APIs you use in Apps targeting the UAP are in the Windows Runtime, which projects into every language, not just the managed languages. Microsoft Office is now a family of UAP apps. What UI technology does it use? Thanks to this relationship, the XAML platform is rich with features and controls that Microsoft and third-party developers, like you, can use in their Windows apps.
Thanks to this relationship, the XAML platform is hyper-performant, delivering rendering capabilities for sub-second performance if you take advantage of it. What you see in Microsoft apps you can do, too. To deliver real value to users, your Windows app needs to light up on different devices. Thanks to the extensibility of the UAP, you can include device-specific code in a single binary that will run on every device.
You get more than one single binary with the UAP, you also get one Store for everything—for phone, tablet, desktop and even Xbox apps. The experience is simplified; the monetization is simplified; and the metrics to monitor marketplace success are simplified, as well. That one Store and the platform let you deploy assets appropriately. And the capability in Windows 8 to package assets targeting specific resolutions and scale remain in the UAP. As always, you stay in control.
You choose which family of devices your Windows app will support. The Windows Store ensures your app is delivered to the device families you select. The value to you is not just broader reach, but an easier overall experience.

In the end, you and your team build Windows apps using what you already know. With great power comes great responsibility.
This is awesome, but it comes with a caveat: Not every device provides the same UX. This means that although you get to employ many of the same responsive Web design RWD techniques you use in your Web applications, you must think through how your Windows app workflow plays out on different types of devices intended for different types of use. Microsoft provides generous tooling to help build responsive and adaptive Windows apps. Visual Studio can simulate aspect ratio, scale and size during design time.
This lets you test Windows apps and finesse your experiences along the way. The XAML toolbox has several new controls and enhancements to help you create responsive and adaptive interfaces that look great on every device and every size display. It inherits from Panel like every other layout control, such as Grid and StackPanel, but allows designers and developers to position child elements relative to other child elements. The resulting XAML visual tree is simpler to render and far simpler to manipulate in response to layout changes. Visual States are another enhancement for XAML developers, making it simpler to respond to layout changes.
This is important: The UI is rich and so is the feature set. Runtime checking using the Windows. ApiInformation namespace empowers you to include device-specific capabilities that light up your apps for the best possible UX on every device. New features and converged controls are the building blocks you need to dream big. Windows apps are the evolution of those apps. This article concentrates on new features in the UAP—for running Windows apps across device families.
You use the Blank App template to build a Windows app. Where are all the other templates? Consider the Hub App template that shipped with Windows 8. Many developers used it. Many developers copied it. Now, the Blank App template is at center stage, encouraging developers to create visually consistent yet distinctive interfaces on the platform. Many community-based templates have already started appearing in the Visual Studio Gallery, including one, Template10, that was written by the authors of this article.
Hello World! Though the UI is blank, it can already run on every Windows device. Your solution includes other familiar support files. The Package. The XML schema has been expanded, but is about the same as the appxmanifest for Windows 8. Where are the two heads? Windows 8 universal apps required both a Phone and a Windows head project. Instead, you adapt your interfaces to accommodate to wherever your Windows app is running. Both approaches are equally supported. Including Content When you open MainPage. The designer is richer and faster; the ability to simulate aspect ratio and scale has improved; and the tooling itself is expanded.
Thanks to our colleague David Crawford for this sample. The code in Figure 3 creates the page header for a simple app for a fictional airline. The fonts and custom Brush resources are declared in App. Note that the bitmap image is at one scale. If you want to accommodate devices with higher resolution, you could scale your assets and name them using the appropriate scale factor so every user gets the best visual experience without downloading assets for other scale factors. Running on Devices Back in MainPage. To run the app, you can select the target in the Visual Studio device target dropdown.
The phone emulators are in the same list.
Choose and run on Local Machine and afterward on one of the Phone emulators to see your Windows app run on different devices without any special compilations. You might have noticed that running a Windows app on the Local Machine, in other words on the desktop of your PC, is a windowed experience and not the full-screen experience of Windows 8. The mobile SKU of Windows 10 still launches Windows apps full screen to make touch navigation easier. But, the desktop SKU of Windows 10 will also launch Windows apps full screen if you choose the touch experience through the Continuum interface on a tablet or a convertible laptop.

The header text is too big for the small screen and is truncated. This is the beginning of a longer journey to test and improve the UX on the variety of possible devices for this Windows app. This allows for a narrow experience on both the desktop and the phone. The Visual State Manager allows developers and designers to define different Visual States meaning different screen layouts and to switch among them at runtime.
They do away with the programmatic approach to switching Visual States. In Figure 4 , notice that there are three Visual States declared: Each of these Visual States corresponds to different ranges of screen width. Replace " ", "" ; if hex. ToByte hex.
Substring pos, 2 , 16 ; return new SolidColorBrush Color. The name 'Color' does not exist in the current context. That appears to be the solution for Silverlight apps? Mike does it solved your problem? Got further with this: FromArgb 0xFF, 44, 50, 50 ; Only issue that I have now is that all of the regular Grid elements overwrite this background color - so it is immediately overlayed with black grids the default for the dark theme.
Plenty to Consider
This is what finally worked for me in my App. FromArgb 0xFF, 44, 50, 50 ; rootFrame.
