This section provides an overview of what uwp is, and why a developer might want to use it.
It should also mention any large subjects within uwp, and link out to the related topics. Since the Documentation for uwp is new, you may need to create initial versions of those related topics.
BackgroundTaskBuilder, but the application will throw an exception if you register a task twice, so you must check if you have already registered a task.BackgroundExecutionManager.RequestAccessAsync(), but make sure that you really have the permission. The call returns the type of access (BackgroundAccessStatus enum) which will indicate whether you have access or not.BackgroundAccessManager. One method to know if your app is updated, is to register another task with a SystemTrigger, type of SystemTriggerType.ServicingComplete.The {x:Bind} markup extension—new for Windows 10—is an alternative to {Binding}.
{x:Bind}lacks some of the features of {Binding}, but it runs in less time and less memory than {Binding} and supports better debugging.
At XAML load time, {x:Bind} is converted into what you can think of as a binding object, and this object gets a value from a property on a data source. The binding object can optionally be configured to observe changes in the value of the data source property and refresh itself based on those changes. It can also optionally be configured to push changes in its own value back to the source property. The binding objects created by {x:Bind} and {Binding} are largely functionally equivalent. But {x:Bind} executes special-purpose code, which it generates at compile-time, and {Binding} uses general-purpose runtime object inspection. Consequently, {x:Bind} bindings (often referred-to as compiled bindings) have great performance, provide compile-time validation of your binding expressions, and support debugging by enabling you to set breakpoints in the code files that are generated as the partial class for your page. These files can be found in your obj folder, with names like (for C#) .g.cs.
For more information please see the MSDN documentation on x:Bind
All examples that fetch data from a remote URL, has to have "Internet (client)" capability checked in the Package.appxmanifest. For examples that only manipulate local data it's not necessary.
Refer the official Data binding documentation from Microsoft.

| Qualifier | Usage | Values |
|---|---|---|
| Lang / Language | Specifies a language, region or both. | XX-XX, or XX values in BCP-47 |
| Scale | Qualifies the device scale factor. | Commonly 100 / 125 / 150 / 200 / 400 |
| DeviceFamily | Specifies the device type. | Mobile / Team / Desktop / IoT |
| Contrast | Specifies the contrast theme type. | Standard / High / Black / White |
| HomeRegion | Specifies user's home region. | Any ISO3166-1 alpha2 or numeric code |
| TargetSize | Gives the smallest image larger than need. | Any positive integer. |
| LayoutDir | Specifies a layout direction. | RTL / LTR / TTBRTL / TTBLTR |
| Config | Qualifies for MS_CONFIGURATION_ATTRIBUTE_VALUE. | The value of environment config. |
| DXFL* | Specifies a DirectX feature level. | DX9 / DX10 / DX11 |
* Also used as DXFeatureLevel.
HomeRegion won't accept groupings or unions.TargetSize and Scale cannot be used together.UWP allows you to take full control of the advantages of Windows 10. Some of these advantages are graphical, as the Accent color or Dark/Light themes.
To prepare your app to be compatible with these feature, a bunch of premade colors have been implemented in UWP to change with the Accent color of the OS the program runs on, or with the theme choice of the user.
There are two "ways" of doing this :
Diretly in Xaml, using the Color = {ThemeResource x} Attribute (or whatever attribute that takes a Brushas value, like BorderBrush, Background, etc.)
In C# Code Behind, by Searching for the color in the Resource directory of the current app. This gives a Color object, so if you want to put it in the Color property of an object you referenced from your Xaml, you'll need to make a new brush like this :
new SolidColorBrush(Application.Current.Resources["yourColorKey"])
For a reference of color keys in c#, please consult :
