正确组织C＃中项目之间的依赖关系

Question

Good afternoon. How should I organize the following structure using C#, the .NET platform, and Visual Studio projects?

The solution should contains several projects (dll or winmd as result). FrameworkB and FrameworkC depend on FrameworkA . ClassA from FrameworkA , ClassD from FrameworkB , and ClassF from FrameworkC are public and visible to framework users; other classes are not accessible to them (there is no possibility to create objects or call a methods). In this case, from ClassE and ClassG we should be able to use the methods from ClassB and ClassC .

So:

• FrameworkA , FrameworkB , and FrameworkC should be a different .dll or .winmd files (But B and C depend on A ).
• ClassB , ClassC , ClassE , and ClassG should be private to framework end-users, but B and C should be visible and used by E and G .

Solution
    FrameworkA
        ClassA
        ClassB
        ClassC
    FrameworkB
        ClassD
        ClassE
    FrameworkC
        ClassF
        ClassG

Answer 1

As per this answer , you could use an InternalsVisibleTo attribute and use Internal access modifier on classes B and C.

That way, classes from the first assembly can be used by other two, but not by client written software.
