Copy a Silverlight Solution/Create a Project Template

[KeithGanzenmuller]

Hopefully and easy question.
Lets say I have a basic solution that I want to reuse, it has all the standard tools and base layers that I will need for most of the the Silverlight websites I will create and the names of the projects in the solution are:
BaseProject & BaseProject.Web

What is the easiest way to create a new solution based on this base one?
I see the Export option in Visual Studio but it exports one of the two projects at a time which I can pick from a dropdown.

There are MSDN documentation and forum thread about this. You can take a look at the following:
