Windows App SDK 1.8 Experimental 4 introduces exciting new features designed to bring artificial intelligence (AI) to your products with the power of Phi Silica and Windows AI APIs.

The Windows App SDK incorporates advanced Windows AI capabilities, enabling developers to seamlessly integrate intelligent features into their applications. These enhancements include:

• The introduction of Windows Machine Learning (WinML) brining hardware-accelerated machine learning capabilities to Windows applications.
• Windows AI Prompt Size validation determines if an input exceeds the allowable size for a text summarization call.
• Windows AI Text rewriter tone enabling specific tones in text rewrite of: Casual, Formal, and General.
• Windows AI Conversation Summarization in a targeted language, enhancing localization and user experience.

This release also include the following:

• Renamed the Microsoft.WindowsAppSDK.Packages component package to Microsoft.WindowsAppSDK.Runtime to better reflect the package's purpose.
• Removed duplicate .winmd files for AI components. For more information see Windows App SDK GitHub Issue #5439
• Addressed a potential crash in ApplicationDataProvider::GetStateFolderUris caused by reentrancy. For more information see Windows App SDK GitHub Issue #10513
• Addressed a UI bug where the TitleBar displayed incorrect spacing when a short title was used. For more information see Windows App SDK GitHub Issue #10492
• Addressed a UI bug where the CalendarDatePicker control displayed incorrect icon margins when a long header was set. For more information see Windows App SDK GitHub Issue #10469
• Resolved an issue related to versioning mismatches between WIndowsAppSDK and Windows SDK NuGet packages, which can cause new projects to fail to build out of the box. For more information see Windows App SDK GitHub Issue #10467 Addressed a regression where the mouse wheel input was ignored if the "Scroll inactive windows when hovering over them" setting was disabled, making windows appear perpetually inactive. For more information see Windows App SDK GitHub Issue #10091
• Addressed a deployment bug where failing to set $(WindowsPackageType)=MSIX in the project file prevents the Deployment Manager from being added, causing apps to require admin privileges unexpectedly. For more information see Windows App SDK GitHub Issue #8182
