-->Windows 10 build 17763 (also known as the October 2018 Update or version 1809), in combination with Visual Studio 2019 and the updated SDK, provide the tools, features, and experiences to make remarkable Universal Windows Platform apps. Install the tools and SDK on Windows 10 and you're ready to either create a new Universal Windows app or explore how you can use your existing app code on Windows.
This is a collection of new and improved features and guidance of interest to Windows developers in this release. For a full list of new namespaces added to the Windows SDK, see the Windows 10 build 17763 API changes. For more information on the highlighted features of Windows 10, see What's cool in Windows 10. In addition, see Windows Developer Platform features for a high-level overview of both past and future additions to the Windows platform.
Design & UIThe Windows 10 October 2020 Update will be rolling out next month. SOPA Images On Tuesday, Microsoft's Windows 10 ($150 at Amazon) October 2020 Update began rolling out for all Windows 10 users.
FeatureDescription
App icons and logosThe app icons and logos page has been rewritten, and now shows the latest Visual Studio icon tools and provides information on adding images to your app's listing in the Microsoft Store.
Design landing pageThe updated Design landing page has an at-a-glance overview of UWP design areas and information on the latest additions to Fluent Design.
Fluent Design controlsThe following new UI controls have been added, to enhance the Fluent Design System and the apparence of your apps: 
 * CommandBarFlyout lets you show common user tasks in the context of an item on your UI canvas. 
 * DropDownButton, SplitButton, and ToggleSplitButton provide button controls with specialized features to enhance your app's user interface. 
 * MenuBar shows a set of multiple top-level menus in horizontal rows. 
 * NavigationView now supports Top navigation, for cases in which your app has a smaller number of navigation options and requires more space for content. 
 * TreeView has been enhanced to support data binding, item templates, and drag and drop.
Fluent Design updatesVisual updates and minor changes have been made to the following Fluent Design pages: 
 * Alignment, padding, margins
 * Color
 * Fluent Design for Windows apps
 * Introduction to app design
 * Navigation basics
 * Responsive design techniques
 * Screen sizes and breakpoints
 * Style overview
 * Writing style
 In addition, we've rewritten the following pages with all-new information on their content areas: 
 * Icons now provides practical recommendations for using icons and making them clickable. 
 * Typography consolidates information from similar articles, putting everything in a single place with updated guidance and illustrations.
Gaze input and interactionsGaze interactions allow your app to track a user's gaze, attention, and presence based on the location and movement of their eyes. This feature can be used as an assistive technology, and provides opportunities for gaming and other interactive scenarios where traditional input devices are not available.
Handwriting viewHandwritingView is the new ink input surface for TextBox and RichEditBox.​ Users can tap a text control with their pen to expand the control into a writing surface. This guidance explains how to manage and customize the HandwritingView in your application.
Motion in Fluent DesignThe use of motion in the Fluent Design System is evolving, built on the fundamentals of timing, easing, directionality, and gravity. Applying these fundamentals will help guide the user through your app, and connects them with their digital experience by reflecting the natural world. Learn more in these articles: 
 * The Motion overview has been updated to reflect these fundamentals. 
 * Motion-in-practice provides examples of how to apply these fundamentals within your app. It also contains information on Implicit Animations, which allow for easy interpolation between old and new value when a XAML element's property is changed. 
 * Directionality and gravity solidifies the user's mental model of your app. 
 * Timing and easing adds realism to the motion in your app. 
 * XAML property animations allow you to directly animate properties of a XAML element, without needing to interact with the underlying composition Visual.
Page transitionsPage transitions navigate users between pages in an app. They help users understand where they are in the navigation hierarchy, and provide feedback about the relationship between pages.
Text scalingThe new text scaling guidance explains how to update your applications to accommodate the new text scaling behaviors, which provide the ability for users to change relative font size across both the OS and individual applications. Instead of using a magnifier app (which typically just enlarges everything within an area of the screen and introduces its own usability issues), changing display resolution, or relying on DPI scaling (which resizes everything based on display and typical viewing distance), a user can quickly access a setting to resize just text, ranging from 100% (the default size) up to 225%.
ToolkitsThe Adobe XD and Adobe Illustrator toolkits have been updated with new features. These design toolkits provide controls and layout templates for designing UWP apps.
UI commandingUpdates to the UWP commanding infrastructure include a better encapsulation of a command object (behavior, label, icon, keyboard accelerators, access key, and description) and a standard set of common commands including cut, copy, paste, exit, etc., which eliminates the need to set these properties manually. 
 The new XamlUICommand class provides a base class for defining the command behavior of an interactive UI element that performs an action when invoked. This is the parent class for StandardUICommand, which exposes a set of standard platform commands with pre-defined properties.
Windows UI LibraryThe Windows UI Library is a set of NuGet packages that provide controls and other user interface elements for UWP apps. These packages are also compatible with earlier versions of Windows 10, so your app works even if your users don't have the latest OS version. 
 For more information on what's in the Windows UI Library, see this list of API namespaces included in the NuGet package.

UWP Controls in desktop applicationsWindows 10 now enables you to use UWP controls in WPF, Windows Forms, and C++ Win32 desktop applications. This means that you can enhance the look, feel, and functionality of your existing desktop applications with the latest Windows 10 UI features that are only available via UWP controls, such as Windows Ink and controls that support the Fluent Design System. This feature is called XAML islands. 
 We provide several ways to use XAML islands in your applications, depending on the application platform you are using. WPF and Windows Forms applications can use a set of controls in the Windows Community Toolkit that provide a designer-oriented development experience. C++ Win32 applications must use the UWP XAML hosting API in the Windows.UI.Xaml.Hosting namespace. For more information, see UWP controls in desktop applications. 
NOTE: The APIs and controls that enable XAML islands are currently available as a developer preview. Although we encourage you to try them out in your own prototype code now, we do not recommend that you use them in production code at this time.
Windows Machine LearningWindows Machine Learning has now officially launched, providing features like faster evaluation and support for cutting-edge machine learning models. To support developers who want to integrate it into their applications, we have created a new documentation site with several new and updated resources:

Windows Mixed RealityDevelopers can now request hardware-protected backbuffer textures if supported by the display hardware, allowing applications to use hardware-protected content from sources like PlayReady. Hardware protection support and setting is available for the primary layer by using new properties of Windows.Graphics.Holographic.HolographicCamera, and for Quad layers via Windows.Graphics.Holographic.HolographicQuadLayerUpdateParameters.
IoT CoreIf you log on to Windows 10 using a Microsoft account with an Outlook.com, Live, Hotmail, or MSN address, that account is added to the Mail and Calendar apps. You can add that and many other email accounts to the Mail and Calendar apps to start sending.
