What does an init accessor, as in public string Name { get; init; }, allow in C#?
Correct answer D. The property can be set only during object initialisation, then becomes read-only
Explanation
Init-only setters, added in C# 9, allow assignment in a constructor or an object initialiser such as new Person { Name = "Ali" }, and in with expressions. After the object is constructed, any further assignment is a compile error. This gives immutable objects while keeping the convenient initialiser syntax, and positional record properties use init by default.
