When you start with a Specific Page while debugging your project, and you are using Local IIS, you might have filled a wrong value in the Specific Page textbox.
当您在调试项目时从特定页面开始并且使用本地 IIS 时，您可能在特定页面文本框中填充了错误的值。
(via Project Properties > Web > Start Action > Specific Page)
（通过项目属性 > Web > 开始操作 > 特定页面）
Wrong configuration:
错误的配置：
Specific Page: "http://localhost/MyApplication/Start/SpecificPage.aspx"
Project Url: "http://localhost/MyApplication"
Right configuration:

Instead of installing the bloated IIS, I get mine resolved by installing Internet Information Services Hostable Web Core from the Windows Features

If you are okay with using the built in Visual Studio Development server or you don't want to or cannot install IIS, you can change the web server the project uses by going into
如果您可以使用内置的 Visual Studio 开发服务器，或者您不想或无法安装 IIS，则可以通过进入更改项目使用的 Web 服务器
Project Properties (right click project in solution explorer and select properties)
select Web tab
select "Use Visual Studio Development Server".
项目属性（右键单击解决方案资源管理器中的项目并选择属性）
选择网页标签
选择“使用 Visual Studio 开发服务器”。
I don't know how it happened to me, but somehow this option was changed to "Use Local IIS Web Server" for one of my projects.
我不知道它是如何发生在我身上的，但不知何故，对于我的一个项目，此选项已更改为“使用本地 IIS Web 服务器”。

For me, it was happening because I had switched over to "Run as Administrator". Just one instance of VS was running, but running it as admin threw this error. Switching back fixed me right up.
对我来说，这是因为我已经切换到“以管理员身份运行”。只有一个 VS 实例正在运行，但以管理员身份运行它会引发此错误。切换回来修复了我。

This occurred to me when I applied the 2017 Fall Creator Update. I was able to resolve by repairing IIS 10.0 Express (I do nothave IIS installed on my box.)
当我应用 2017 秋季创作者更新时，我想到了这一点。我能够通过修复 IIS 10.0 Express 来解决（我的机器上没有安装 IIS。）
Note:As a user pointed out in the comments,
注意：正如用户在评论中指出的那样，
Repair can be found in "Programs and Features" - the "classic" control panel.
修复可以在“程序和功能”-“经典”控制面板中找到。

Modify was greyed out for me, but adding the IIS Management Console under programs and features fixed this for me. Also on Windows 10 fall update.
修改对我来说是灰色的，但是在程序和功能下添加 IIS 管理控制台为我解决了这个问题。同样在 Windows 10 秋季更新中。
