Drag and Drop from one SIlverlightDesktop module to another has finally been checked in.
Currently the Drag and Drop allows you to drag text elements from the WhoAmI module and drop them on the Notepad module and have the Notepad module import the contents.
To understand how the process works take a look at the "proof of concept" we created back in August: Silverlight Drag and Drop Test .
The reason the integration took so long is that we knew Microsoft was planning to release Silverlight 2.0 and did not want to have to fix it as well as the other Silverlight 2.0 breaking changes that were expected.
We hope to have the latest version of SilverlightDesktop released in the next 30 days. There will be no breaking changes (and we have no plans of any breaking changes in the future) so you will be able to simply install the upgrade package when it is released.
