The null coalescing operator is right-associative, meaning that operations are grouped from right to left.

> *Example*: An expression of the form `a ?? b ?? c` is evaluated as a `?? (b ?? c)`. In general terms, an expression of the form `E1 ?? E2 ?? ... ?? EN` returns the first of the operands that is non-`null`, or `null` if all operands are `null`. *end example*

The type of the expression `a ?? b` depends on which implicit conversions are available on the operands. In order of preference, the type of `a ?? b` is `A₀`, `A`, or `B`, where `A` is the type of `a` (provided that `a` has a type), `B` is the type of `b`(provided that `b` has a type), and `A₀` is the underlying type of `A` if `A` is a nullable value type, or `A` otherwise. Specifically, `a ?? b` is processed as follows:
