I get the following error pretty regularly when compiling in Visual Studio and running my web application:
在Visual Studio中编译并运行我的web应用程序时，我经常会遇到以下错误:
"Unable to start debugging on the web server. The web server did not respond in a timely manner. This may be because another debugger is already attached to the web server."
无法在web服务器上启动调试。web服务器没有及时响应。这可能是因为web服务器已经附加了另一个调试器。
Normally this is after having debug the application once already. From the command line I run "iisreset /restart" and it fixes the problem.
通常这是在已经调试了应用程序一次之后。我从命令行运行“iisreset /restart”，它修复了问题。
How do I prevent this from happening in the first place?
首先，我要如何防止这种情况的发生?

I find that this happens if I'm debugging with Firefox as my browser. When I exit Firefox the VS2005/8 debug session doesn't terminate. I have not found a solution for this (yet).
如果我使用Firefox作为我的浏览器进行调试，就会出现这种情况。当我退出Firefox时，VS2005/8调试会话不会终止。我还没有找到解决这个问题的方法。
If this is what's happening with you then a quicker solution than running iisreset is to hit Shift-F5 when in Visual Studio and this will terminate the current debug session. You can then hit F5 and this will start a new debug session.
如果这就是发生在您身上的事情，那么比运行iisreset更快的解决方案是在Visual Studio中按Shift-F5，这将终止当前的调试会话。然后单击F5，这将启动一个新的调试会话。

The solution that worked for me:
对我起作用的解决方案是:
-
Open Command Prompt (Run as Administrator)
打开命令提示符(作为管理员运行)
-
Write
iisreset /restart写iis重启/重启
-
Now, go back to your VS and debug. It will debug your solution.
现在，回到VS和debug。它将调试您的解决方案。
It worked for Visual Studio 2013 and 2015 too in my case.

After trying all of the proposed solutions here and in other places (at least 10 different approaches), the only option that worked for me was:
在这里和其他地方尝试了所有建议的解决方案(至少有10种不同的方法)之后，对我有效的唯一选择是:

- 删除IIS上的网站和应用程序池
- re-create website and application pool on IIS (in my case, everything exactly the same config as before)
- 在IIS上重新创建网站和应用程序池(在我的例子中，所有配置都与以前完全相同)
PS: I am using VS 2013 and IIS 7.5 (Win7).

We use another way of debugging, we never use F5 anymore.
我们使用另一种调试方法，不再使用F5。
We use a macro kind of like: http://blogs.conchango.com/howardvanrooijen/archive/2007/06/24/Attach-to-Web-Server-Macro-for-Visual-Studio.aspx (Which we bound to F6).
我们使用类似的宏:http://blogs.conchango.com/howardvanrooijen/archive/2007/06/24/ attachto web - server - macro for visual - studio.aspx(我们绑定到F6)。
This way you simply attach the debugger to IIS. It's (depending on project size) much quicker to make you changes, compile a single project that you changed and attach the debugger again.
这样，只需将调试器附加到IIS。它(取决于项目的大小)更快地使您进行更改，编译您更改的单个项目，并再次附加调试器。

I have had this problem a couple times. One time it was resolved by taking Guy's advice:

On a separate occasion I had to: terminate all my iis worker processes in the windows task manager (w3wp.exe*). You should be able to hit f5 in visual studio to debug.
在另一个场合，我不得不:在windows任务管理器(w3wp.exe*)中终止所有iis worker进程。您应该能够在visual studio中点击f5进行调试。

It sounds like you are probably hitting F5 in Visual Studio when you receive this error?
当你收到这个错误时，你可能会在Visual Studio中点击F5 ?
There are a few things you can try. The easiest is to hit the Stop button before hitting F5. Optionally, when you are finished debugging and starting to make changes you can go to the Debug menu and choose either Stop Debugging or Terminate All.
有一些事情你可以尝试。最简单的方法是在按F5之前按下停止按钮。可选地，当您完成调试并开始进行更改时，您可以转到Debug菜单中，选择停止调试或全部终止。

It sounds like something is eating up your web server's resources. Perhaps you have some resources (file handlers, wcf proxies) that are being opened and not closed? I've had this happen to me specifically when I was not closing WCF client proxy connections.
这听起来像是在吞噬你的网络服务器的资源。也许您有一些资源(文件处理程序、wcf代理)正在打开而没有关闭?我在没有关闭WCF客户端代理连接时就遇到过这种情况。
The problem is not necessarily that you have a debugger attached, but only that the web server is not responding in a timely manner. Note that the message says "This may be because another debugger is attached".

I ran into this issue when trying to debug (2) separate solutions in VS.NET and both were using the IIS Web Server to launch the app. The 1st application will start, but any subsequent applications started that also run via IIS will then display that error. It seems that it can only debug a single application via VS.NET hosted in IIS at a time.
我在试着调试VS.NET中的(2)单独的解决方案时遇到了这个问题，他们都在使用IIS Web服务器来启动应用程序。似乎它一次只能通过IIS托管的VS.NET调试一个应用程序。
The solution: run project 1 from VS.NET (place any needed breakpoints) and start the second application directly from IIS (not VS.NET). Your breakpoints in App 1 (running in VS.NET) will be hit when accessing App 2 (ran from IIS directly).
解决方案:从VS.NET运行project 1(放置任何需要的断点)，并直接从IIS(而不是VS.NET)启动第二个应用程序。当访问App 2(直接从IIS运行)时，你在App 1中的断点(在VS.NET中运行)将会被击中。

我花了一些时间尝试用通常的方式来解决这个问题，但是即使重新启动我的工作站，这个问题仍然存在。最后我发现SQL Server (MSSQLSERVER)服务没有运行。
It should have been running, as it's set to Automatic, but it was stopped, even after the reboot. All the MSSQLSERVER events in the event log appeared normal, so it remains unknown why it wasn't running, but I have now set it to Automatic (delayed start) in the hope that this will reduce resource contention during startup.

This worked for me by @mtkachenko Visual Studio 2012: Unable to attach the process. A debugger is already attached "I have installed Debug Diagnostic Tool v2.0 and as a result I have Debug Diagnostic Service which is started automatically and attached to one of w3wp processes. After turning off and disabling this service all works fine. So if you get such error check processes in task manager which can capture your w3wp process"

This worked for me by @mtkachenko Visual Studio 2012: Unable to attach the process. A debugger is already attached "I have installed Debug Diagnostic Tool v2.0 and as a result I have Debug Diagnostic Service which is started automatically and attached to one of w3wp processes. After turning off and disabling this service all works fine. So if you get such error check processes in task manager which can capture your w3wp process"
@mtkachenko Visual Studio 2012: can ' t attach process。“我已经安装了调试诊断工具v2.0，因此我有了调试诊断服务，它将自动启动并附加到w3wp进程之一。”关闭和禁用此服务后，一切正常。如果你在任务管理器中得到这样的错误检查过程可以捕获w3wp过程
