Are value types immutable by definition?

Question

I frequently read that structs should be immutable - aren\'t they by definition?

Do you consider int to be immutable?

int i         


        

Answer 1

Mutability and value types are two separate things.

Defining a type as a value type, indicates that the runtime will copy the values instead of a reference to the runtime. Mutability, on the other hand, depends on the implementation, and each class can implement it as it wants.
