Code inspection: Replace with FirstOrDefault($args$)

This inspection reports a conditional expression that checks Any(...) before calling First(...), and returns default(T) when there is no match. That pattern is equivalent to FirstOrDefault(...).

Example

                var result = items.Any(x => x.IsValid) ? items.First(x => x.IsValid) : default(MyType);
            

var result = items.FirstOrDefault(x => x.IsValid);

Quick-fix

Replace the Any(...) ? First(...) : default(T) pattern with FirstOrDefault(...).
