Thanks for message. This is not exactly what i'm looking for but i think i'll work around using your solution.
My goal is to inject the resources in the module from the shell. The idea is as follow:
1. i've just received the .dll of the module
2. no way to change anything in the module
3. i'have a documentation telling me the keys and the types of the resources defined in the module.
Based on these informations i'll change the resources as i want.
May be the composition application guidance doesn't deal with this issu because all modules have to know the shell (View injection or discovery).
In my idea no module know the shell. Only the shell knows the nodules.
