(VB.NET)大家看看这是什么问题

c#using System.Web;namespace Acme {    public class SimpleHandler : IHttpHandler {

        public void ProcessRequest(HttpContext context) {
            context.Response.Write("Hello World!");
        }        public bool IsReusable {
            get {
                return true;
            }
        }
    }
}
为什么C#的就能编译成功,真FT
