WebAbstraction can be achieved with either abstract classes or interfaces (which you will learn more about in the next chapter). The abstract keyword is used for classes and methods: Abstract class: is a restricted class that cannot be used to create objects (to access it, it must be inherited from another class). Beginning with C# 11, an interface may declare static abstract and static virtual members for all member types except fields. Interfaces can declare that implementing types must define operators or other static members. This feature enables generic algorithms to specify number-like behavior.
