Thread Safety

Members of this class are thread-safe if you previously called IXRApplication::CreateHostFromXaml and supplied it with an XRWindowCreateParams structure that has AllowsMultipleThreadAccess set to true.

Remarks

Basic shapes such as a line do not support a Bézier curve. To draw a Bézier curve, you can use an IXRPath and set the data to one of the Bézier geometries.

When you create a class instance, use an IXRLinePtr smart pointer instead of a raw interface pointer. For more information, see XRPtr<Interface>.

You can also define a line in Microsoft Silverlight 3 XAML. For information about the differences between XAML in XAML for Windows Embedded and Silverlight 3, see Differences Between Microsoft Silverlight 3 and XAML for Windows Embedded. For more information about how to define this element in the source XAML for your application, see the Line Class on MSDN.
