How do properties work with value types - why so?

Question

.NET

The question is caused by this article https://m.habr.com/ru/post/124404/ Fiddle link https://dotnetfiddle.net/uFhUvl
In the fiddle code, the IncrementX method accesses the X autoproperty of the int value type and increments it, those. purely logically, at first the getter should return not a reference to the field, but a copy of the field, and then the increment operation changes the value of the copy. As a result, at least the result should have been 5, not 6, and as a maximum, the "Cannot modify the return value of 'something here' because it is not a variable" exception should have fallen. But in fact, the result is 6, not 5, and there are no exceptions. Can anyone explain?

Answer 1

Uh X++=> X = X + 1The value of the copy then changes, but then it is written back.
