Windows App SDK 1.7.2 (1.7.250513003)

WinAppSDK 1.7.2 is the latest stable version of WinAppSDK providing new features and improvements to the platform. WinAppSDK 1.7.2 introduces exciting new features designed to bring artificial intelligence (AI) to your products with the power of Phi Silica and Windows AI APIs.

Whats new in WinAppSDK 1.7.2: * Phi Silica, Microsoft's most powerful NPU-tuned local language model, you can 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. * Image Description APIs enable the generation of textual descriptions of images. * Text recognition, also known as optical character recognition (OCR), detects and extracts text within images, converting it into machine-readable character streams. * The 'ImageScaler' APIs can increase the sharpness and clarity of an image and upscale the image by up to 8x its original resolution. * The Image Segmentation APIs allow for the identification of specific objects within an image. By inputting an image and a "hints" object, the model returns a mask of the identified object. * ApplicationData.MachineFolder is now easier to use on Windows >=10.0.26100.0 (Ge). Windows will create the Machine [folder](https://github.com/microsoft/WindowsAppSDK/blob/main/specs/applicationdata/ApplicationData.md#343 when a package manifesting opt-in [support](https://github.com/microsoft/WindowsAppSDK/blob/main/specs/applicationdata/ApplicationData.md#342 is added to a system if WinAppSDK 1.7.2 is present on the system.

This release also includes the following Bug Fixes: - Fixed PackageDeploymentManager telemetry to properly capture completion status. For more info, see GitHub issue #5296. (RuntimeCompatibilityChange: N/A) - Fixed a crash when using pen input on an x86 app. (RuntimeCompatibilityChange: InputStateManager_PenInputCrashX86) - Fixed a potential crash if the window is already destroyed when WinUI is attempting to initialize for scrolling. (RuntimeCompatibilityChange: ActivateDirectManipulationManager_CheckCanInit) - Fixed the WINDOWSAPPSDK_RELEASE_PATCH define and Microsoft::WindowsAppSDK::Release::Patch values in WindowsAppSDK-VersionInfo.h to not always be 0. The define is now the yymmdd date of the build, and the Patch value is the mmdd date. This change provides better runtime information on the version being used without changing any variable sizes or the version scheme. (RuntimeCompatibilityChange: N/A, header change) - Fixed a potential issue in the Bootstrapper if it is used to load a 1.6 or earlier version of WinAppSDK. For more info, see GitHub issue #5349. (RuntimeCompatibilityChange: N/A) - Fixed an issue where using MSBuild to build a single-project app could incorrectly fail with a build error if it didn't have a correct launchSettings.json. (RuntimeCompatibilityChange: N/A, build .targets change) - Improved the performance of rendering the first frame on application launch. (RuntimeCompatibilityChange: DwmCoreI_OptimizeFirstFrameLatency)
