您好Alvaro R ivoir，

>>是否可以使用  直接操作？我想从ui线程处理触摸事件，以便能够将转换应用于元素。

WPF使应用程序能够响应触摸。例如，您可以使用触摸敏感设备上的一个或多个手指与应用程序进行交互，例如触摸屏本演练创建一个应用程序，使用户可以移动，调整大小，
或旋转单个对象使用触摸。欲了解更多信息，请参阅：

以下是WPF中支持多点触控的完整示例供您参考。

Hi Alvaro Rivoir,

>>Is it possible to use Direct Manipulation in WPF? I want to process touch events off the ui-thread to be able to apply transformations to an element.

WPF enables applications to respond to touch. For example, you can interact with an application by using one or more fingers on a touch-sensitive device, such as a touchscreen This walkthrough creates an application that enables the user to move, resize, or rotate a single object by using touch. for more information, please refer to:

https://docs.microsoft.com/en-us/dotnet/framework/wpf/advanced/walkthrough-creating-your-first-touch-application

Here is complete sample about Support multi-touch in WPF for your reference.
