Link dependencies of a c# library

Question

I have project B depending on project A which is a library that has it's own dependencies.

In project A I reference the assemblies that define Dependency1Base<T> and Dependency2Class , and define MyClass like this:

namespace MyNamespace
{
    public class MyClass: Dependency1Base<Dependency2Class>
    {
    }
}

In project B , I just reference project A and try to instance MyClass

namespace MyNamespace
{
    public class B
    {
        public void main ()
        {
            var myInstance = new MyClass();
        }
    }
}

Project A builds fine, but when I try to build project B , I get an error telling me that Dependency1Base and Dependency2Class are defined in an assembly that is not referenced. So I'm wondering if there is a way to link this definitions in project A so that I don't have to add those references to project B ? or do I always need to reference the dependencies of project A in any other project that uses MyClass ?

Answer 1

Yes, you do need to reference everything class or object you use in your project. But you don't have to reference more than that.

If you have a class C that inherits from B , which itself inherits from A :

In C , you must reference B , and if you use some properties or method that come from A , you must reference A as well

In B , you must reference A

In `A, you don't have to reference anything.
