Question: Constructors can not be static

Answer: C# supports two types of constructor, a class constructor (static constructor) and an instance constructor (non-static constructor).

Static constructor is used to initialize static data members as soon as the class is referenced
first time, whereas an instance constructor is used to create an instance of that class with
<new> keyword. A static constructor does not take access modifiers or have parameters and can't access any non-static data member of a class.

Since static constructor is a class constructor, they are guaranteed to be called as soon as we refer to that class or by creating an instance of that class.

There is nothing as "Static constructor is a class constructor", every constructor is a class constructor no matter it is static or not. The static constructor is used to initialize static fields. Moreover, static constructor is used when we declare constructor as private and want to create a single instance of that class i.e, single design pattern where constructor is private and static.
