Uses of the ternary operator condition ? then : otherwise
Null-coalescing operators ?? and ??=

- for loops and foreach loops
- while loops
- do-while loops

catch blocks
logical binary operations && and ||
pattern combinators and and or
everything counted for the "functions" metric

It does not count:

case guards with the keyword when
Default switch expression arms with syntax _ => expression
goto labels

functions

The "functions" metric counts:

methods and the accessors get, set and init in classes, abstract classes, interfaces and records
constructors
lambda expressions

classes

The "classes" metric counts:

definitions of class, abstract class, interface, enum and record
