Why are C# structs immutable?

Asked 2010-09-20T13:28:53.450

I was just curious to know why structs, strings etc are immutable? What is the reason for making them immutable and rest of the objects as mutable. What are the things that are considered to make an object immutable?

Is there any difference on the way how memory is allocated and deallocated for mutable and immutable objects?

A struct type is not immutable. Yes, strings are. Making your own type immutable is easy, simply don't provide a default constructor, make all fields private and define no methods or properties that change a field value. Have a method that should mutate the object return a new object instead. There is a memory management angle, you tend to create a lot of copies and garbage.
