问题
Can a .Net namespaces span multiple assemblies? Specific examples would be helpful.
回答1:
Yes.
Eg. System is, some of it is in mscorlib.dll, other parts are in System.dll and System.Core.dll (and, I assume, others).
回答2:
Yes. And this is the right approach to separate different logic parts of your application.
YourApp.Dal - separate assembly with data access layer.
YourApp.Infrastructure - separate assembly with some infrastructure.
YourApp.Web - web part of your application.
