static constructor from C#

1) The static constructor for a class executes before any instance of the class is created.
2) The static constructor for a class executes before any of the static members for the class are referenced.
3) The static constructor for a class executes after the static field initializers (if any) for the class.
4) The static constructor for a class executes at most one time during a single program instantiation
5) A static constructor does not take access modifiers or have parameters.
6) A static constructor is called automatically to initialize the class before the first instance is created or any static members are referenced. 
7) A static constructor cannot be called directly.
8) The user has no control on when the static constructor is executed in the program. 
9) A typical use of static constructors is when the class is using a log file and the constructor is used to write entries to this file.
