interlock exchange issue

Hello everyone,


How to fix the compile error when interlock exchange a bool type variable?

Code:

---

    public static void Main()
    {
        bool b = false;

        // error CS0452: The type 'bool' must be a reference type in order to use it as parameter
        // 'T' in the generic type or method 'System.Threading.Interlocked.Exchange<T>(ref T, T)'
        bool a = Interlocked.Exchange(ref b, true);

        return;
    }

---

thanks in advance,
George

The MSDN examples state that you should be using an int instead. While this is also a non-referencetype, there are overloads of Exchange for int.
