Why value-types are stored onto Stacks?

Question

Why does C# (.Net) prefer stack to store value types? What is the primary reason behind this design? Is it because read/write operations to the stack take better advantage o

Answer 1

Your statement isn't totally true. A better version: C# stores local variables on the stack.
And this isn't special or new, (almost) all programming languages use the stack for local variables and method return addresses. There is support for this down to the hardware.

Furthermore, Valuetypes can be local variables or fields inside reference types. So valuetypes are not always stored on the stack. A more helpful statement: referencetypes are never stored on the stack.

So don't focus on the stack too muuch, it's an implementation detail. Learn about value- and reference-types.
