Any call to a class (static or constructor call), triggers the static constructor execution. Static constructors are thread safe and implement a singleton pattern.

"Scope" and "context" in particular are frequently confused: scope is a property of a name binding, while context is a property of a part of a program, that is either a portion of source code (lexical context or static context) or a portion of run time (execution context, runtime context, calling context or dynamic context).
Braces enclose either a literal list of set elements, or a rule that defines the set elements. [65] For example: S = {a, b} defines a set S containing a and b. [65] S = {x | x > 0} defines a set S containing elements (implied to be numbers) x 0, x 1, and so on where every x n satisfies the rule that it is greater than zero. [65]
