I'm having this error trying to debug my ASP.NET MVC app. I've set the app to "Use Local IIS Web server", and selected ASP.NET as the debugger. Running the site without debugging works just fine, but when I try to debug, I got this error:
我正在尝试调试ASP。我将app设置为“使用本地IIS Web服务器”，并选择了ASP。净的调试器。在不进行调试的情况下运行站点效果很好，但是当我尝试进行调试时，我得到了这个错误:
Unable to start debugging on the web server. The web server could not find the requested source.
I'm using Visual Web Developer 2008 Express Edition.
我使用的是Visual Web Developer 2008 Express Edition。

Go to your web project's properties, then the "web" tab, then make sure that you're using the Visual Studio Development Server and not Local IIS or the custom webserver. I'm on VS2010 with Win7 and another developer was developing using a custom webserver URL and not the VS Dev Server

I had the same problem, and i fixed this way:

如果您正在使用IIS6并在IIS技巧中为.*做了添加映射以使MVC工作，那么当您将.*处理程序添加到iisapi时。你忘记取消勾选“勾选文件存在”复选框。

Also, be sure that the URL you're configuring in Visual Studio matches your Host Headers (Edit Bindings) in IIS. This tripped me up for about an hour this morning before I realized my very stupid error.
另外，请确保在Visual Studio中配置的URL与IIS中的主机头(编辑绑定)匹配。今天早上，这句话把我绊倒了一个小时，直到我意识到我犯了一个非常愚蠢的错误。

This happened to me today. Turned out to be that the default website was stopped in iis. I had been working on a second website that didn't use it for a long time. Simple fix but took me a while to see it!
今天发生在我身上的事。原来是iis中的默认网站被停止了。我一直在开发第二个网站，很久没有使用它了。简单的修复，但我花了一段时间看它!
