asp.net - 唯一数据库不是唯一的吗？-- 使用 IIS7 设置 ASP.net 站点的问题

Question

好吧，我已经四处搜索，但没有人的解决方案可以解决我的问题。

这是我得到的错误（无论如何它的屏幕截图）：

当我从 Visual Studio 中运行该站点时，该站点运行良好。

有人有什么想法吗？我以前从未在 IIS7 中运行过站点（或者在 IIS 中），所以我在进行过程中有点生气。

这是我的默认页面源：

<%@ Page Title="" Language="VB" MasterPageFile="~/master/default.master" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>
