[Injeckt via Digitalmars-d-learn]

I'm trying use classes in my project, but when i'm try inherit 
class, I get error:

        Error: import `Server.Console` is used as a type

Server.d:

        module Server;

        import std.string;
        import core.sys.windows.windows;
        import Console;

        class Server : Console {
            this(HANDLE hIn, HANDLE hOut) {
                super(hIn, hOut);
            }

            ~this() {
                // Delete object;
            }
        }


Console.d:

        module Console;

        import std.string;
        import core.sys.windows.windows;

        class Console {
            public:
                HANDLE hIn;
                HANDLE hOut;

            this(HANDLE hIn, HANDLE hOut) {
                this.hIn = hIn;
                this.hOut = hOut;
            }
        }

What does it mean?
