How are some of you managing multi-project solutions, normally fine in Visual Studio, but for front-end developers who only need/understand Webmatrix?

We've got a number of solutions that have eg business logic, usercontrols, etc in other projects, typically either referenced from the main web app project, or using post-build events to copy their stuff to the main web app project.

However, for Webmatrix users, this is no good - they can only open the web app, so are missing the other bits.. they've no need to work with them, just need them present in order to run the website. We could commit these outputs to source control, but that doesn't feel very good practice either.

Anyone willing to share if/how they manage this?
