Is DataGridDragDropTarget gone from the latest version of Silverlight toolkit?

Question

I'm using Silverlight 4 and Silverlight Toolkit April 10 release (dll is referenced from this folder: %Program Files%\Microsoft SDKs\Silverlight\v4.0\Toolkit\Apr10\Bin). However, after registering the namespaces, adding toolkit:DataGridDragDropTarget to XAML results in this error:

`The tag 'DataGridDragDropTarget' does not exist in XML namespace 'clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Toolkit'.`

Though, other DragDropTargets are available: ListBoxDragDropTarget, PanelDragDropTarget, TreeViewDragDropTarget.

I suspect it was some kind of omission mistake by the toolkit team when preparing the distribution package: if you download the toolkit source code (from here: http://silverlight.codeplex.com/releases/view/43528) and check the archive's Bin folder, System.Windows.Controls.Data.Toolkit.dll dll is there - that's the one that now contains the DataGridDragAndDrop itself. Just copy it to the rest of your tollkit distribution dlls and reference from your project:

    <dataToolkit:DataGridDragDropTarget
                x:Name="DragAndDrop"
                xmlns:dataToolkit="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data.Toolkit"
                AllowDrop="True" >
