Anyway why would you derive a class with private constructor and instantiate that?

class Base
{
   public int x;

   public Base() { x = 20; }
}

class Derived : Base
{
   public Derived() {}
}

Derived d  = new Derived();
Console.WriteLine(d.x);

Are you saying that the C# compiler implicitly calls the base's constructor?

class Base
{
   public Base(int x){}
}

class Derived : Base
{
   public Derived() {} // won't compile, as compiler attempts to call Base() and
                       // no default constructor exists.
}

That's why you'll see code like this fail to compile

will it call the parent's parameterless constructor for all of the child's constructors if you do not explicitly call a specific base constructor?
