You can firstly deploy your web application/site with your iis, then open your visual studio 2010. Then click "File"->open->website->Local IIS Site, then select your website/application. Then you will find that the debug may works. This method works for my case.

You have not mentioned what operating system you are using. But this might not be related to operating system. I am taking a guess here. If you are running on Windows 7, try running visual studio under Administrator previlages.

You can also try adding your user ID to the VS debugger users group. You can access user groups by reight clicking on computer name or my computer and selecting Manage. Under that you can find Users &amp; Groups.

Your solution file in visual studio is broken. It's a known issue when converting from a file-system website to an IIS website, and it has been carried over from 2008 to 2010. Not sure of the location for the bug report on ms's kb site, though.

Remove the website from the solution file (right click the project name, click "remove"). Then right click the solution name, click "add existing web site". When the dialog to add a web site comes up, choose "from IIS" in the left-hand pane. Navigate to your application in IIS, select "use secure sockets layer" if necessary, and click "finish" (or whatever that button is labeled).

this will permanently fix the issue.

These steps my differ depending on your version of Windows. I am using 7 with iis 7.

Open IIS Manager, click on Application Pools and find the 2 ASP.NET v4.0 pools (One is called "ASP.NET v4.0" the other "ASP.NET v4.0 Classic". Chances are that first one is stopped. Do not start it yet, we need to investigate a bit more.

For the "ASP.NET v4.0" pool, check the name in the Identity Field. Is it ApplicationPoolIdentity? Remember the name.

Open Computer Management (right click on My Computer and select Manage). Expand Event Viewer, then Windows Logs. Click on Application and wait for the data to load. There should be an error with a source of User Profile Service with a message that starts with "Windows cannot log you on because your profile cannot be loaded. Check that you are connected to the network, and that your network is functioning correctly."

If you do find that, then you have the same problem as I did.

The Solution: Go back to IIS Manager and right click on "ASP.NET v4.0" and select Advanced Settings. Under Process Model, the first field is Identity. Change this from ApplicationPoolIdentity to NetworkService. Click OK.

Now start the pool if it did not restart automalically. Go back to your application and press F5 (start debug) and your application should work.

Please note that I have not figured out why this works, and this may be a security risk, but at least you will be able to do some work while you think about this.

I had the same issue on Win7 and VS2010 (without ReSharper) and found that Skype listened on port 80. IIS listens to port 80 by default. This can occur when you set VS to debug an existing web application running in IIS instead of the built in ASP.NET debug web server.

I solved the issue by unchecking "Use ports 80 and 443 as alternatives for incoming connections." in Skype under Tools -> Options -> Connection, followed by a restart of Skype.

I got a new PC with <code>Windows 7</code>. I installed <code>VS2010</code> and my development environment and hoped my F5 debug problem would be gone, but it still failed to start the debugger. 

This was a good clue since it ruled out the install of software.

I finally traced it down to my HOSTS file. I had an entry for some of my local websites which I can access like "<a href="http://testsite.lcl" rel="nofollow noreferrer">http://testsite.lcl</a>" but the IP I had assigned was my machine's IP instead of using <code>127.0.0.1</code> so it looked like a remote server to VS2010.

It may also be because of some special or illegal format in your config file i will suggest you to check for that first .

In my case i was getting an error because of that when i tried to browse my service from IIS it showed me the real error .

I tried every single solution put online to resolve this issue and nothing seems to work consistently.

I eventually solved it in both 2010 and 2012 by tracking it down to the following missing file in the Debug Source Files setting

<pre><code>C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\atlmfc\src\mfc\
</code></pre>

Solution > Properties > Debug Source Files >

Check to ensure all the files are there then remove this entry and everything worked again.

blocks|key|1030666|text|您是否更改了IIS网站上的绑定？如果是这样，您需要转到您的项目属性，选择Web选项卡，并更改project+Url以匹配您的绑定。因此，在显示http:///yourwebsite的位置将其更改为http:///yourwebsite|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1030667|这对我很有效。|1030668|entityMap|0|LINK|mutability|MUTABLE|url|http://yourwebsite/|1^0|1Z|J|0|2Q|J|1|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@$A|P|B|Q|1|R]|$A|S|B|T|1|U]]|C|$]]|$1|D|3|E|5|6|7|V|8|@]|9|@]|C|$]]|$1|F|3|-4|5|6|7|W|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|M]]]]

Did you change your bindings on your IIS website? If so, you need to go to your project properties, select the Web tab, and change the Project Url to match your binding. so where it says http:///yourwebsite change it to http:///yourwebsite

This worked for me.

blocks|key|1245698|text|在我的例子中，是web.config中的system.webServer+>+httpErrors+>+errorMode导致了这个问题。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1245699|如果你有errorMode="Custom"，试试这个：|1245700|<httpErrors+errorMode="DetailedLocalOnly">|code-block|syntax|javascript|1245701|有关https://stackoverflow.com/a/15585629/631277重写的变体和其他想法，请参阅答案:+URL|1245702|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/a/15585629/631277^0|K|15|0|4|I|0|0|2|17|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@$9|X|A|Y|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|Z|8|@$9|10|A|11|B|C]]|D|@]|E|$]]|$1|H|3|I|5|J|7|12|8|@]|D|@]|E|$K|L]]|$1|M|3|N|5|6|7|13|8|@]|D|@$9|14|A|15|1|16]]|E|$]]|$1|O|3|-4|5|6|7|17|8|@]|D|@]|E|$]]]|P|$Q|$5|R|S|T|E|$U|V]]]]

In my case it was the <code>system.webServer &gt; httpErrors &gt; errorMode</code> in the web.config that caused the problem.

If you have <code>errorMode="Custom"</code> try this:

<pre><code>&lt;httpErrors errorMode="DetailedLocalOnly"&gt;
</code></pre>

blocks|key|1245767|text|另一件可以尝试的事情(这就是我的工作)：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1245768|在IIS中，单击应用程序池>(您的站点)>高级设置，并将“启用32位应用程序”更改为True。|1245769|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Another thing to try (this is what worked for me):

In IIS, click Application Pools > (Your Site) > Advanced Settings, and change "Enable 32-Bit Applications" to True.

blocks|key|1030839|text|我在Visual+Studio+2013上也遇到了同样的问题。在我的例子中，我从IIS中删除了“默认网站”。为了解决这个问题，我再次创建了默认网站，将物理路径设置为C:\inetpub\wwwroot，将端口设置为80+(默认端口)。重新启动Visual+Studio后，它工作得很好。希望这能帮助到别人。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1030840|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I had same issue with Visual Studio 2013. In my case I had removed the "Default Web Site" from IIS. To resolve the issue I created the default website again, set physical path to C:\inetpub\wwwroot and port to 80 (default port). After restarting the Visual Studio it worked perfectly. Hope it helps someone.

I get error message "Unable to start debugging on the web server" in Visual Studio 2010. I clicked the Help button and followed the related suggestions without success.

This happens with a newly created local ASP.Net project when modified to use IIS instead of Cassini (which works for debugging). It prompts to set debug="true" in the web.config and then immediately pops up the error. Nothing shows up in the Event Viewer.

I am able to attach to w3wp to debug. It works but is not as convenient as F5.

I also have a similar problem with VS2008 on the same PC. Debugging used to work for both.

I have re-registered Framework 4 (aspnet_regiis -i). I ran the VS2010 repair (this is the RTM version). I am running on a Windows Server 2008 R2 x64 box.

I do have Resharper V5 installed.

There must be some configuration setting or registry value that survives the repair causing the problem.

I'd appreciate any ideas.
