Dereferencing a null pointer, a pointer to an object outside of its lifetime (a dangling pointer), a misaligned pointer, or a pointer with indeterminate value is undefined behavior, except when the dereference operator is nullified by applying the address-of operator to its result, as in &*...

Because this always points to the implicit object, we don’t need to check whether it is a null pointer before dereferencing it. Resetting a class back to default state If your class has a default constructor, you may be interested in providing a way to return an existing object back to ...
I would use this attribute in your final sample to: Decorate field Value. This will allow us to remove null-forgiving operator in the assignment Value = default. Compiler will not warn us about Possible null reference assignment, because now it knows that null value can be assigned to the ...
