Visual Studio 2013-IIS Express不提供aspx文件

Question

I was compelled by work to upgrade from Visual Studio 2010 to Visual Studio 2013. In VS 2010, I used the built-in host for viewing .net apps locally and everything worked just fine. Visual Studio 2013 dropped support for the built-in host and compels everyone to use IIS Express.

My trouble is that IIS Express won't serve up "[anything].aspx" no matter where in the folder tree of the project it resides. I created two test files in the root of the project: HelloWorld.html and HelloWorld.aspx (c#) and made both to simply show a page saying "Hi" with the asp.net file showing the current date and time. I then copied these two test files into an arbitrary folder in the project. After building the project (unnecessary, I know), I did a "View in Browser" for all test files. In all cases, the HTML files displayed properly. The aspx files cause a "HTTP 400 Bad Request" / "The webpage cannot be found" error.

I've prowled Stack Overflow and Google and read about some near-misses but ultimately came up empty for this specific problem. I'm hoping this is a simple configuration issue, but the answer so far eludes me. Thanks in advance for your kind assistance!

Edit:

Thanks to Lex Li's suggestion of using the Jexus Manager to see what's going on with the IIS Express configuration, it shows that zero apps are assigned to any of the default application pools. Correspondingly, when clicking on the home of the website in the Jexus Manager, the .Net section of the website is absent.

Edit #2:

The web app is assigned to one of the default IIS Express app pools: Clr4ClassicAppPool.

听起来很奇怪，您是否尝试打开iis express xml applicationhost.config并检查其中的mime类型或应用程序池设置？
