Public class not accessible

Question

Hy guys,

I am having a weird situation with a behavior of this class, and I am not understanding the reason.

Could you please help me?

I have this Class Teste.cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace RMAFF.Engine
{
    public class Teste
    {
        public int TesteFunction()
        {
            int teste = 10;

            return teste;
        }

    }
}

And I am trying to access the function TesteFunction() in this other class Teste2.cs, but no success. I can access the class Teste, but I can't access the public function TesteFunction.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace RMAFF.Engine
{
    class Teste2
    {
        void caramba()
        {
            Teste.[the function do not appears here]
        }
    }
}

Thanks in advance.
