问题
I want to add the ability to drag a user control from one part of a Silverlight 4 page onto another user control on the same page (not talking about the new Silverlight 4 ability to drag a file from the OS onto the page).
What approach is most straightforward? What approach offers the most flexibility?
Here are some alternatives I found so far
- SO drag-and-drop-control-for-silverlight. Same question but answers apply to SL 2.
- Alex van Beek's DragManager. Written for SL3.
- Silverlight Drag Drop. Also written for SL3.

I can't compare all of the options you've listed but if I wanted to implement control to control drag drop feature I would the DragDrop and the DragDropTarget classes from the Silveright Toolkit. Its the only DragDrop framework I know of that has been refreshed for SL4 and if you already use elements from the Toolkit then that would be a natural solution.
