Latest experimental channel release notes for the Windows App SDK

  • Article

Important

The experimental channel is not supported for use in production environments, and apps that use the experimental releases cannot be published to the Microsoft Store.

The experimental channel includes releases of the Windows App SDK with experimental channel features in early stages of development. APIs for experimental features have the Experimental attribute. If you call an experimental API in your code, you will receive a build-time warning. All APIs in the experimental channel are subject to extensive revisions and breaking changes. Experimental features and APIs may be removed from subsequent releases at any time.

Version 1.7 Experimental (1.7.0-experimental3)

Use on-device AI with Windows Copilot Runtime APIs

Important

The underlying ML models required for these APIs currently require your device to be running the latest Windows 11 Insider Preview Build on the Dev Channel. Additionally, these APIs require your device to be a Copilot+ PC. See Copilot+ PCs Developer Guide to learn more about these devices. APIs will throw an exception when called on devices lacking the necessary support.

The Windows Copilot Runtime (WCR) offers several AI-powered features and APIs for you to easily, efficiently, and responsibly use on-device AI models in your Windows apps. In this release we are making available several scenario focused APIs for you to leverage powerful capabilities without the need to find, run, or optimize your own Machine Learning (ML) models.

Learn more about responsible development practices used during WCR API development that you can also apply as you create AI-assisted features in the Developing Responsible Generative AI Applications and Features on Windows guidance.

Phi Silica

With Phi Silica, Microsoft's most powerful NPU-tuned local language model, you can generate text responses to broad user prompts with built in content moderation. You can also specify it to perform common tasks like summarizing a piece of text, rewriting a piece of text for clarity, and converting text to a table format. Phi Silica is optimized for efficiency and performance on Windows Copilot+ PCs devices while still offering many of the capabilities found in Large Language Models (LLMs).

See Get started with Phi Silica in the Windows App SDK and API ref for Phi Silica in the Windows App SDK for more information.

Text Recognition (OCR)

Text recognition, also known as optical character recognition (OCR), APIs in Windows Copilot Runtime (WCR) can detect and extract text within images and convert it into machine readable character streams. These APIs can identify characters, words, lines, polygonal text boundaries, and provide confidence levels for each match. The set of WCR AI-assisted APIs benefit from NPU-assisted acceleration to perform faster and more accurately than the legacy Windows.Media.Ocr.OcrEngine APIs.

See Get Started with Text Recognition (OCR) in the Windows App SDK and API ref for AI-backed Text Recognition (OCR) in the Windows App SDK for more information.

Image Super Resolution

Using the 'ImageScaler' APIs you can increase the sharpness and clarity of an image and upscale the image up to 8x its original resolution.

See What can I do with Image Super Resolution? and API ref for AI imaging features in the Windows App SDK to get started.

Image Description

The Image Description APIs can be used to generate a text description of an image. The APIs are configurable to specify the length and type of the text description. Image descriptions may include a short caption or a long description for users with accessibility needs.

Note

When calling ImageDescriptionGenerator.DescribeAsync() in a Debug build, an error may occur that can be mitigated by continuing the build in Visual Studio.

See What can I do with Image Description? and API ref for AI imaging features in the Windows App SDK to learn more.

Image Segmentation

Using Image Segmentation APIs you can identify specific objects within an image. The model takes both an image and a "hints" object and returns a mask of the identified object.

See What can I do with Image Segmentation? and API ref for AI imaging features in the Windows App SDK to get started.

New APIs for Windowing

New AppWindow APIs make it easier to control your app windows and create a great experience. New capabilities include using EnablePlacementPersistence to automatically remember the size and position of your windows, using SetTaskBarIcon and SetTitleBarIcon to independently set the taskbar and titlebar icons, using AppWindowTitleBar.PreferredTheme to set the light/dark theme of the titlebar, and using OverlappedPresenter.PreferredMinimum/MaximumSize to set a minimum or maximum size for the window.

Other notable changes

  • The missing C# projections for the new BadgeNotifications have been added so these APIs are now usable from C#.
  • A class registration issue which prevented using the new AppNotificationConferencingConfig API has been fixed. Note that this enhanced user experience for video or audio calling in notifications is only available on the latest Windows Insider releases of Windows.

Background Task Registration

A new BackgroundTaskBuilder API enables registering background tasks for Windows App SDK apps. For more info, see GitHub #4831.

New Notifications Features

New badge notification support allows showing a number or glyph badge on your app in the taskbar. For more info, see GitHub #4926.

Important

In this release, the C# projections are missing for the new BadgeNotifications APIs, which prevents using them from C#. The APIs are available in C++.

Video or audio calling can have an enhanced user experience in notifications. For more info, see GitHub #4783.

Important

This functionality is only available on the latest Windows Insider releases of Windows.

Other notable changes

  • RichEditBox now supports math mode, via RichEditTextDocument.SetMathMode and RichEditTextDocument.SetMath.
  • New CompatibilityOptions support will allow more control over how servicing changes affect apps. For more info, see GitHub #4976.

Bug fixes

This release includes the following bug fixes:

  • Changed SplitButton so touch input now matches the behavior of mouse input. For more info, see GitHub issue #178.
  • Changed cascading menus so sub menus now open immediately if clicked. For more info, see GitHub issue #939.
  • Fixed an issue where opening a ComboBox which is in a flyout closes all flyouts. For more info, see GitHub issue #1467.
  • Fixed an issue where SwipeControl would randomly crash in a ListView. For more info, see GitHub issue #2527.
  • Fixed an issue where drag-and-drop only a ListViewItem would leave it in the wrong visual state. For more info, see GitHub issue #3458.
  • Fixed an issue in StackLayout so that it respects the ItemsRepeater.HorizontalAlignment and ItemsRepeater.VerticalAlignment properties (when StackLayout.Orientation is Vertical and Horizontal respectively). The old layout behaved as if the ItemsRepeater alignment was Stretch. With the fix, the layout results in items aligned to the right when the Right alignment is used, for example. For more info, see GitHub issue #3842.
  • Fixed an issue where deleting items in the ItemsRepeater's source would not generate items which moved up into view. For more info, see GitHub issue #6661.
  • Fixed an issue where the right Alt key would not show keytips for Access Keys. For more info, see GitHub issue #8447. Note: This may result in key events for the right Alt key no longer being delivered to handles in the app or controls.
  • Fixed a crash where UniformGridLayout would sometimes pick a wrong layout anchor and cause infinite layout passes when scrolling backwards. For more info, see GitHub issue #9199.
  • Fixed an issue where setting NavigationFailedEventArgs.Handled to True would still throw an exception. For more info, see GitHub issue #9632.
  • Fixed an issue where TabView would not apply any specified CornerRadius. For more info, see GitHub issue #9846.
  • Fixed a potential layout cycle crash in StackLayout. For more info, see GitHub issue #9852.
  • Fixed a potential crash in ItemsView when removing items. For more info, see GitHub issue #9868.
