InternalsVisibleTo , different member variables to different assemblies

Question

I have a class A_class in Project A. In class A_class, there is a constructor

internal A_class()
 {
  //constructor logic
 }

, and a member variable internal int A_member;

Now there are two friend assemblies, say Assembly B and Assembly C I want Assembly B to be able to access only and only A_Class() I want Assembly C to be able to access only and only A_member Such that, Assembly B can not access A_member, and Assembly C can not access A_class()

Is it possible ? Or is there any other alternative for this ?

If i use

[assembly: InternalsVisibleTo("B")]
[assembly: InternalsVisibleTo("C")]

Then both B and C will have access to both A_class() and A_Member, which is not desired

Answer 1

The attribute InternalsVisibleTo is applied only at the assembly level

The attribute is applied at the assembly level.

You cannot provide differentiated access to the class and member as you desire.
