You can’t call an abstract class constructor with a class instance creation expression , i.e. As constructors of abstract classes can only be called within subclass constructors (and by chaining one to another within the same class), I typically make them protected … making them public would serve no purpose.19 Haz 2014

Read moreWhat is an abstract method in C#?
An Abstract method is a method without a body . The implementation of an abstract method is done by a derived class. When the derived class inherits the abstract method from the abstract class, it must override the abstract method. This requirment is enforced at compile time and is also called dynamic polymorphism.14 Mar 2019
