Static Constructors

Although the runtime provides type initializers for more than just classes and structs, C# restricts their declaration to those categories of types (mainly because of their limited use of other types).

A static constructor looks like an instance constructor but is declared via the static keyword, doesn’t have an access modifier, and can’t take any parameters. Just like any other static member, it can only access other static members and is primarily used to assign the type’s static fields. In fact, static field initializers ...
