Boxing vs Unboxing

Question

Another recent C# interview question I had was if I knew what Boxing and Unboxing is. I explained that value types are on Stack and reference types on Heap. When a value is cast

Answer 1

Here's another interesting variation that supports Stefan's comments:

        int i = 2;
        object a = i; // Boxing
        object b = a; // Referencing same address on heap as 'a', b == a

        b = i; // New boxing on heap with reference new address, b != a
