Is it possible to use P/Invoke in native blocks?

[ghost]

Can I treat the code inside native blocks just like normal C# code in a C# source file?

#if CS
native {
    using System;
    using System.Runtime.InteropServices;

    class PInvokeHelper
    {
        // Import user32.dll (containing the function we need) and define
        // the method corresponding to the native function.
        [DllImport("user32.dll", CharSet = CharSet.Unicode, SetLastError = true)]
        public static extern int MessageBox(IntPtr hWnd, string lpText, string lpCaption, uint uType);
    }
}
#endif

public class Program
{
    public static void Main()
    {
#if CS
        native {
            PInvokeHelper.MessageBox(IntPtr.Zero, "Command-line message box", "Attention!", 0);
        }
#endif
    }
}
