问题描述

我有一个ASP.NET Web API上运行时工作正常IIS前preSS与本地主机：1783

I have an ASP.NET Web API which works fine when running on "IIS Express" with localhost:1783

但是，当我未交使用IIS前preSS，然后preSS创建虚拟目录...

But when I uncross the "Use IIS Express" and then press "Create Virtual Directory"...

...我只是得到404错误：

...I just get 404 errors:

任何想法什么是错？谢谢！

推荐答案

我不明白为什么，但像的这个答案，加入 runAllManagedModulesForAllRequests =真正的并解决问题。

I don't understand why but like said in this answer, adding runAllManagedModulesForAllRequests="true" did the trick.

<system.webServer>
    <validation validateIntegratedModeConfiguration="false"/> <-- this was here
    <modules runAllManagedModulesForAllRequests="true"/> <-- this did the trick
</system.webServer>

如果谁能够解释为什么？

Anybody who can explain why?
