I know it's a Windows PE32, but I also know that the unit of deployment in .NET is an assembly which in turn has a manifest and can be made up of multiple managed modules.

My questions are :

1) How would you create multiple managed modules when building a project such as a class lib or a console app etc.

2) Is there a way to specify this to the compiler(via the project properties for example) to partition your source code files into multiple managed modules. If so what is the benefit of doing so?

3)Can managed modules span assemblies?

4)Are separate file created on disk when the source code is compiled or are these created in memory and directly embedded in an assembly?
