Putting using statement inside the namespace fails

I was trying to get some of the old code properly styled with stylecop. It asks for putting the using statements inside. It worked well for all but one. I have reduced the problem to the below code. 

namespace B.C
{
    using System;

    public class Hidden
    {
        public void SayHello()
        {
            Console.WriteLine("Hello");
        }
    }
}

namespace A.B.C
{
    using B.C;

    public class Program
    {
        static void Main(string[] args)
        {
            new Hidden().SayHello();
        }
    }
}

this gives compilation error Error

"The type or namespace name 'Hidden' could not be found (are you missing a using directive or an assembly reference?)".

If I move using B.C; above the namespace A.B.C then it builds properly. The class Hidden is developed by different team and we cannot modify it.

B.C is conflicting with A.B.C. You need to rename B.C to something else or specify it with global

As you are inside the namespace A, then B.C will actually be A.B.C.

Use global:: to specify that you are looking from the root:

using global::B.C;
