郁闷的COM与dotnet组件互操作

按照MSND示列文档(http://msdn2.microsoft.com/zh-cn/library/c3fd4a20(VS.80).aspx),新建了一个C#类库项目(ClassLibrary1).class1.cs    using System.Runtime.InteropServices;    [Guid("EAA4976A-45C3-4BC5-BC0B-E474F4C3C83F")]
    public interface ComClass1Interface
    {
    }    [Guid("7BD20046-DF8C-44A6-8F6B-687FAA26FA71"),
        InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]
    public interface ComClass1Events
    {
    }    [Guid("0D53A3E8-E51A-49C7-944E-E72A2064F938"),
        ClassInterface(ClassInterfaceType.None),
        ComSourceInterfaces(typeof(ComClass1Events))]
    public class ComClass1 : ComClass1Interface
    {
    }设置项目属性:"为COM Interop注册","为程序集签名".
然后"生成ClassLibrary1",并将ClassLibrary1.dll拖入C:\WINDOWS\assembly中.asp中
<%
    dim tmp
set tmp=server.CreateObject("ClassLibrary1.ComClass1")
%>出现:
错误类型：
Server 对象, ASP 0177 (0x800401F3)
无效的类别字符串 请教如何解决??
很急呀!
