> The Microsoft.WindowsAppSDK.ML NuGet package has been refactored, adding a new base dependency. The existing ML NuGet package's functionality remains the same, but the core Windows ML features have been refactored into a base dependent package called Microsoft.Windows.AI.MachineLearning. This new package contains a minimal set of dependencies, but on C#/WinRT or C++/WinRT it only supports down to Windows 10 18362. If you need Windows 10 17763 support, use the existing Microsoft.WindowsAppSDK.ML package.
31
+
>
32
+
> For new transitive dependencies, we recommend using tooling to upgrade the package (nuget.exe or VS). See also: [Windows App SDK 1.6 release notes](/windows/apps/windows-app-sdk/release-notes/windows-app-sdk-1-6?pivots=stable).

69

>

+
> Enabled drag support for WebView2 content hosted in WinUI 3 applications. This capability was previously unsupported and is now available without introducing new public APIs. Note: Drop into WebView2 from external sources is already supported.
71
+
>
72
+
> #### Supported scenarios
73
+
>
74
+
> -**Standard drag-and-drop content**
75
+
> Dragging text, HTML, images, and URLs is supported. Based on current behavior, dragging images outside the app results in a default file name (for example, `download.jpg`) when dropped into File Explorer.
76
+
> *Example scenario:* A user selects text or an image inside WebView2 and drags it either within the app or to another destination such as File Explorer.
77
+
>
78
+
> -**Drag cancellation**
79
+
> On-demand cancellation of an active drag operation is supported.
80
+
> *Example scenario:* An app conditionally blocks drag operations for certain content types (such as restricted or ephemeral content) by cancelling the drag after it has been initiated.
81
+
>
82
+
> -**Custom drag visuals**
83
+
> Custom drag UI, such as icons or previews, is supported to help users clearly identify the content being dragged.
84
+
> *Example scenario:* An app displays a thumbnail preview or icon while a user drags media content, making it clear which item is currently being moved.
85
+
>
86
+
> -**Customizable drag data**
87
+
> Editing and customizing drag data is supported, enabling app-specific scenarios such as dragging messages within the app (for example, as an alternative interaction for message forwarding).
88
+
> *Example scenario:* An app customizes the drag payload to include contextual metadata, such as the originating application name. When the content is dropped, the destination can display or process information like "From \<app name\>" to indicate the source of the dragged content.
89
+
>
90
+
> #### Limitations
91
+
>
92
+
> - Support for additional drag data types is limited. The following formats are not currently supported:
93
+
> -`DownloadURL`
94
+
>
95
+
> #### Requirements
96
+
>
97
+
> -**Minimum WebView2 Runtime version (Edge Beta channel):** 144.0.3719.11
> The `IXamlCondition` interface enables developers to define custom conditions that integrate with XAML's conditional namespace syntax and are evaluated at XAML parse time. This is a rename and graduation of the experimental `IXamlPredicate` interface. Custom conditions enable conditional XAML scenarios based on application-specific factors such as feature flags, device capabilities, business logic, configuration settings, and other runtime conditions.

> * Fixed MSB8027 and LNK4042 build warnings caused by duplicate ClCompile items in Windows App SDK NuGet .targets files by moving preprocessor definitions from `<Target>` blocks to `<ItemDefinitionGroup>`. An opt-out workaround (`WindowsAppSDK_Arm64EcCompilerWorkaround`) is included for ARM64EC+LTCG builds to avoid a known MSVC internal compiler error.
114
+
> * Fixed a ListView crash that could occur during keyboard navigation (Tab/Shift+Tab) after the items list was updated.
115
+
> * Fixed an issue where WinUI 3 could crash if focus was moved to the CoreWebView2Controller while the controller was not visible.
