Currently building up a shared WPF controls library and linking to the XAML/CS files from a full-blown WPF application and a Silverlight 3 beta web application. So very impressed by the fact I have a rich client and a web client with exactly the same interface with minimal compromise (ie, watching out for things like CoreCLR doesn't support Label but does support TextBlock etc).

And I've just watched Hackers 2: Operation Takedown. Kevin Mitnick rules.

So yes. Colour me nerdy.

I was just using Visual Studio's 'Add Existing Item' > 'Add As Link' to add a .XAML and .CS file for a control from a Custom Control Library into my Silverlight project. The Silverlight project compiles it into it's own assembly while the custom control library compiles it into itself for use by the thick client.

I'll have a look at ProjectLinker though. Sounds more elegant.

I also believe Da Vinci was an earthworm. But I was shit at Art History.
