描述

The System.Xaml.dll!System.Xaml.Schema.XamlObjectCreationFactory can create object directly by WpfGeneratedKnownTypes help. But we can not find the System.Windows.Media.Animation.BackEase in WpfGeneratedKnownTypes which means we should use the reflection to create the object.

研究方向
The issue reports that System.Windows.Media.Animation.BackEase is missing from the WpfGeneratedKnownTypes list. To fix, locate the file `WpfGeneratedKnownTypes.cs` in the WPF repository, likely under `src/Microsoft.DotNet.Wpf/src/PresentationFramework/System/Windows/Markup/`. Find where other easing functions like `LinearEase` are registered and add an entry for `BackEase`. Check the comments on the issue for any specific guidance or naming conventions. No linked PRs exist, so the fix is open. Ensure the new entry follows the existing pattern (e.g., type name, assembly). Test by building the WPF project and verifying that `BackEase` can be instantiated without reflection.
