When Does the C# Static Constructor Get Invoked?

Occurrence of Static Constructor Invocation in C#

When defining a class that includes a static constructor, it is important to understand when this constructor will be invoked. Contrary to loading the assembly, the static constructor in C# is called when the class is accessed for the first time.

According to the C# Programming Guide, a static constructor exists "to initialize any static data, or to perform a particular action that needs [to be] performed once only." This constructor is automatically called before the creation of the initial instance or any referencing of static members.

Essentially, the static constructor provides initialization for static data and serves as a means of performing actions only once for a class. It allows for the setup of class-wide properties or configurations before the first invocation of any class functionality, making it a valuable aspect of programming in C#.
