I'm having an issue with IIS Express (7.5) crashing whenever I launch a site in Web Matrix 2. The same sites launch fine from VS2010. The IIS icon appears in the tray, with the site listed as a running application, then disappears as soon as Chrome launches. Web Matrix serves the 'following site has stopped: xxxxxx' error.
I've uninstalled/reinstalled IIS Express and Web Matrix, have launched IIS from the command line, including error trace and it's all fine. Have also commented out the HttpLoggingModule key in the applicationhost.config file.
What else could be causing the problem?
Running webmatrix as administrator solved this, so figure it must be a security/permissions setting.

I created a brand new ASP.NET Core Web App project to test out the new features of .NET 6.0.
But when I tried to run the application with F5 nothing displayed on the web browser but "Page Not Found" error.
Also I tried with IIS Express and the result is same. Also tried http and it's same.
I don't have any idea what may be the problem?
After I rebooted my computer project runs well.
But sometimes later problem occurred again. I tried changing ports, rebooting, close and relaunch visual studio. None of them solved the problem.
Must be a computer specific problem but don't have any idea where to start. Really annoying.
So I keep searching and trying, I came up with this solution:
ASP.NET Core 404 Error on IIS 10
dotnet restore
dotnet run
It works for now but the problem related to debugging still persists.
I'm using Visual Studio 2013 with IIS Express 8 to develop an application for a local Intranet. This application was built using ASP.NET MVC 4 in Visual Studio 2012 and later migrated to 2013. I had been using Visual Studio Development Server until I migrated to VS2013 with no issues.
After the migration, the application compiles, runs and authenticates fine, but it's not serving Static Files - it just returns an HTTP 500 response with no further details. See image below:
This also happens to Images and CSS files.
What can I check to solve this? Any suggestions?
UPDATE:
The application works fine in Local IIS (version 8).
It works in IIS Express on other PCs.
UPDATE 2:
After further testing, I found out that this only happens to Mozilla Firefox (it works fine in Internet Explorer and Google Chrome) - I didn't notice before because I always use FF. Currently using version 29.
Any ideas?
Finally! I was able to solve this issue with the help of this question.
This was happening because Firefox by default has Windows Integrated Authentication turned off. It doesn't make any sense to me why it works fine in regular IIS or in dynamic files (controller actions, WebApi, etc.), but that's a mystery for another day.
To enable Windows Integrated Authentication I followed this steps:
Type about:config in Firefox's address bar (nav bar)
Search for network.automatic-ntlm-auth.trusted-uris
Double click on network.automatic-ntlm-auth.trusted-uris
Add http://localhost to the list (paste that if it's empty)
After that I just hit F5 in Firefox and everything worked as expected.
This issue is poorly documented, so I wonder if nobody else uses Firefox with MVC to develop web applications using Windows Integrated Authentication?
Have you had a look at this ?
ASP.NET MVC application gives Internal Server Error only when viewed in Firefox
It doesn't explain why it works on IIS but there is a firefox doesn't support Integration Authentication out of the box.
The only thing that seems applicable to your situation is a problem with the install of IIS Express since this is an similar issue to something seen in previous IIS Express versions. I would either re-install it or see if your version of Windows can host IIS 8 in which you would just enable static content.
If this was just a matter of not having static content turned on or permissions for static content, you'd get a 404 or 401 error respectively. Hope this helps...
I'd look in the machine events viewer under application and system to see what the issue is.
Does the IIS serve anything up in the same folder such as .txt files, .html, jpg images?
It could possible be file or folder permission and/or the anonymous user being used to access them under IIS.
My first point would be event viewer though for more detailed information on the 500 error.
I have sharepoint 2013 application deployed on IIS. When I want to start debugging, I face this error:
"Unable to start debugging on the web server. IIS does not list a web site that matches the launched URL".
I found a few solutions for this issue, but none work for me. The solutions I found:
VS should be running as Administrator. I did that.
Windows Authentication should be enable on IIS. I did that.
'IIS Metabase and IIS 6 configuration compatibility' should be turn on in the Windows features. I did that.
It still doesn't work. Any other solutions? Please help me.
Try to start Visual Studio under administration account by choosing Run as administrator.
If nothing works as above said solutions , try this out
Start >> Control Panel >> Click Programs
Click Turn Windows features on or off.
In the User Account Control dialog box, click Continue
Expand Internet Information Services, expand Web Management Tools, and then expand IIS 6 Management Compatibility
Click to select the IIS Metabase and IIS 6 configuration compatibility check box, and then click OK.
I had this same problem.
I was trying to move my solution to a different DEV server of mine, that I don't use that often.
1.) I had not installed some of the items from the Application Development (duh, right) sections of the IIS Role Services. I ended up checking everything, but I think you only need ASP.NET
2.) I installed the asp.net and web tools 2013 available by clicking here
So I've been working at this for about 2 days now and have essentially hit a dead end. I guess the first thing to know is, can IIS Express work in combination with Visual Studio 2010 and Windows 8?
I just got this new laptop in, with Windows 8 pre-installed. I installed Visual Studio 2010 Ultimate, SP1, and MVC 3. I had to enabled .NET Framework 4.0 myself...
I have a project that I transferred from my old computer (windows 7) to this computer. It was set up to run on IIS Express. So when I opened the project, VS2010 said that I was missing some components and asked if I wanted to install them--so it installed IIS Express for me. When I try to run my project, I get a "This page can't be displayed" page in IE. In fiddler, I get
- 302 HTTP localhost:16683 /
- 502 HTTP Tunnel to localhost:443
the SSL URL for the project is https://localhost:44300/
the URL for the project is http://localhost:16683/
If I go to IISExpress in my system tray and select the https link there, it opens the website up just fine. If I select the http link there, it get that "502 HTTP Tunnel to localhost:443" line in fiddler again... Why is it trying to tunnel to localhost:443???
Another thing to note is that I decided to create a test MVC 3 project from scratch to see what IIS Express would do. I set the project to run on IIS without enabling SSL. When I run the project is starts up just fine. When I click the logon link, it tries to redirect to an https link with port 44300...when it shouldn't be. I created a test project for the same purpose on my windows 7 machine, and the project did not do this.
The last thing to note is that after going to the https link for my initial project via the IIS Express tray icon, if I click the logon link for the test project, it now takes me to my initial project's https link... It's as if the projects are crossing over into each other...
I have recently started to received this message.
Unable to start debugging on the web server.
The IIS worker process for the launched URL is not currently running
Does anyone know what this means?
I created my virtual directory via Properties on the project, and clicking Create Virtual Directory. ANd in IIS I can see it, I run VS 2010 with Admin Privs.
The Application pool in .Net 4.0
Any help really appreciated
Thanks
EDIT
I managed to get it working but its a good workaround really. Basically there was another website setup i.e. Default Website where all my apps goes which was started and running.
And there was another website (which was stopped!) that was for installanywhere.. But it was stopped! ... I removed the site completely and now it works
Can vs 2010 not figure out which one to connect to or something?
I presumed if its stopped then it wouldn't try and connect..
Very confused, Anybody know of alternative work around?
I got the same error message after reinstalling VS2010. In my case all application pools in the IIS where remapped to run 4.0, so VS2010 was unable to figure out which pool to attach its self to during debugging. The solution in my case, was to manually delete few pools and remapping my older pools back to .net 2.0. I finally ended up, only having 2 pools pointing towards .net 4.0 (integrated and classic) and 2 pools running .net 2.0 (integrated and classic).
