visual studio - Organizing multiple Composite WPF applications to share a single Shell -

How can I organize more than one composite WPF application so that they can share a shell project, but different apps Can be able to populate their module catalog from config. Files?

I am writing a suite of applications using Composite Application Guidance for WPF, each application's functionality is determined based on the availability of different modules, which are listed in Shell's App.config . By giving each app a separate app.configging, I can specify which modules can use each application.

However I would like to share a single shell project between all applications for common view and experience. Initially I created a solution for each app, added the Shell project, and then added the relevant module. The problem is that there is only one App.config file in the Common Shell project, and I can not change it on a per-solution basis.

Creating a list through code does not escape the problem - there should still be an application-specific code in shell that can be activated by any kind of solution.

Did I decide that Shell had to behave as a module? Each application has its own solution and project, with individual App.config files. They also have classes on their bootstrap. Instantly gives bootstrapper shell to each application.
