最近我们的网站偶尔会出现上面的错误。
我整理了一下出现这个错误的解决方案：
1。 在iis中项目文件夹设定为虚拟目录
在iis下找到项目文件夹属性－>目录－>应用程序设置处 点击 创建
2。 在站点下面有多个配置文件(web.config)。
删除子目录中的多余文件。
3。 如何配置应用程序的身份验证策略。
a、启动互联网信息服务(IIS)。 b、右键点击你的应用虚拟目录,然后单击属性。 c、点击这个目录安全标签。 d、在匿名访问控制和认证,点击编辑。e、确保匿名访问复选框是未被选中,集成的windows认证被选择。（如果是asp和asp.net混合的站点，那么匿名访问也必须被选择。）
f、 web.config需要<authentication mode="Windows"/>
To resolve this issue you would have to open the main .SLN file in notepad and replace the sections:
Project("{E24C65DC-7377-472B-9ABA-BC803B73C61A}") = "C:"..."MySite"", "C:"Inetpub"wwwroot"MySite",
with
Project("{E24C65DC-7377-472B-9ABA-BC803B73C61A}") = "http://localhost/MySite/", "http://localhost/MySite",
and also if missing, add
SlnRelativePath = "c:"inetpub"wwwroot"MySite""
4. 虚拟目录的权限需要设置ASPNET, IIS匿名， NetWork Service三个用户的权限。
