What would be the purpose of this dll?
As far as I know, in lightswitch it's only possible to use a silverlight control as a custom control in your UI screens for example.
In order to do this, you can add an extra project to your solution that holds the silverlight controls and refer to this project from your lightswitch client project.
Then you can use the "custom control" option in the designer to use a custom control from this project.

A few links that can  help you on your way to creating custom controls for lightswitch:

you should wrap your desktop dll with a web service (WS-* or RESTful), so it can be consumed by the silverlight application comfortably.
