Windows App SDK 1.8.0 (1.8.250907003)

WinAppSDK 1.8.0 is the latest stable version of WinAppSDK providing new features and improvements to the platform.

Whats new in WinAppSDK 1.8.0:

• The new Decimal support offers a high-precision base-10 numeric data type. It is structured as a 96-bit (12-byte) signed integer, scaled by a variable power of 10, allowing for precise representation of decimal values.
• The Windows App SDK NuGet package has been converted to a NuGet metapackage. Each component contributing to the Windows App SDK is now a component NuGet package and is listed as a dependency by the metapackage. This allows developers to choose either the metapackage or select specific component packages for their applications.
• The MSIX publishing support has been factored into a standalone nuget package, which can be independently maintained and consumed by Windows App SDK and other projects.
• Prompt Size Limit Reporting allows applications to determine if an input exceeds the allowable size for a Text Summarizer call. If the input is too large, the API returns an index indicating the current limit, enabling developers to adjust the input accordingly.
• Text Rewriter Tone enables text rewriting with specific tones. Choosing between Casual, Formal, and General options.
• Phi Silica now has a Summarize Conversation feature that allows you to summarize what people have said over an email, chat, or thread.
• Enables developers to specify the desired output language for conversation summarization. This allows applications to generate summaries in a targeted language, enhancing localization, and user experience.
• Object Erase can be used to remove objects from images. The model takes both an image and a greyscale mask indicating the object to be removed, erases the masked area from the image, and replaces the erased area with the image background.
• The Microsoft.Windows.Storage.Pickers API in the Windows App SDK provides a modernized file and folder picker experience for desktop applications. This API is based on the existing Windows.Storage.Pickers API design, but with key improvements for desktop scenarios.
• Prior to WinAppSDK 1.8, packaged apps running in the AppContainer did not require the packageManagement capability, due to a DeploymentManager auto-initialization issue. That issue has now been resolved, and in turn, the packageManagement capability is now required for AppContainer-based apps.
• The experimental WinML APIs have been removed from this release and will be included in a future release.

The following bugs have been fixed:

• #10572 Using App Window.Titlebar in child window causes main window hover UI to flicker badly
• #10464 Splitbutton Incorrect height
• #10524 TabViewItem Header Text has uneven padding when TabWidthMode="SizeToContent"
• Users cannot use the Album and other details pages when sidebar (navigation view is collapsed
• TabView: improper usage of GetFocusedElement
• TabView: RequestClosedTab method

Apologies, this has been fixed.

Version 1.8 has disrupted my localization:
After upgrading from 1.7 to 1.8, localization worked properly during debugging, but when packaged as appxbundle or appx and I installed it, the app's language remained the default English resource, but the CurrentCulture was correct.

Thank you for creating the following issue on this topic:

Colleagues, we really need the InkCanvas component. We’ve been waiting for it for a long time and cannot migrate from UWP.

For several years you’ve been promising to add InkCanvas (starts from WindowsAppSDK 1.6), and with every release we hope to finally see it, but end up only being disappointed.

When do you plan to release this component?

[ChaimCL]

I saw InkCanvas in the experimental version's new APIs back in 1.7. I wonder why it hasn't been released in the stable 1.8 version after all this time. Compared to previous even-numbered versions, the new features in 1.8 are far too few.

Hello @RDMacLachlan. Thank you so much for everyone's work. I am still waiting for Syncfusion to fix their controls for 1.8 localization before I can upgrade, as I am eager to test the decimal support. But that's my own problem 😢

I just wanted to point out that you advertise the WinUI Gallery App above to see the latest changes, but the Microsoft store is still on a version from last May, not 1.8. I checked the repo and see some recent changes. Do you know if the gallery app will be updated soon? Thanks again!

[RDMacLachlan]

Hi @MPITech,
Thank you for the kind words, and for your continued usage of Windows App SDK 😊. An update to WinUI Samples App is coming soon, which will advance it to Windows App SDK 1.8.
