Solution 1

Your base class can't be less accessible then your derived class.
So you can't inherit a internal class to a public class.

VALID CASE:

public class Base
    {

    }

   internal class Derived : Base
    {

    }

INVALID CASE:

internal class Base
    {

    }

    public class Derived : Base
    {

    }

When you are developing a class library that can be used by some other application in that case your public classes needs some helper classes that are not relevant for outside world such classes you make internal.
