What is a static constructor? When should it be used?
 

A static constructor is a special type of constructor in object-oriented programming, specifically designed for initializing a static class or static variables within a non-static class. Unlike regular constructors, it doesn’t take any parameters and can’t be called directly. It’s automatically invoked by the .NET Framework CLR when the class is accessed for the first time.

Static constructors are used to initialize any static data, or to perform a particular action that needs to be performed once only. They’re often used when the class is using a log file and the log file has to be opened once at the beginning. Another use case is when creating singleton classes where we need to ensure only one instance exists throughout the application lifecycle.
