The Unable to start debugging on the Web server message is generic. Usually, a more specific message is included in the error string and that may help you identify the cause of the problem or search for a more exact fix. Here are a few of the more common error messages that are appended to the main error message:

This error may occur when debugging locally with a 32-bit version of Visual Studio, which use the 64-bit version of the remote debugger to debug 64-bit applications. Visual Studio 2019 and earlier are 32-bit applications. Check your App Pool on IIS to make sure that Enable 32-bit applications is set to true, restart IIS, and try again.
Well, this looks like great info and seems to have helped lots of people but I guess my PC is more screwed up than most because I can't even run a web app in VS 2005 without debugging, let alone with. Just get the "can't launch vs localhost web server" error. ASP.Net apps run fine outside of VS via regular IIS. Vista Business 6.0.6000. Have VS SP1 and SP1 Update installed, as well as the 3 items mentioned above in IIS otions. Logged in as administrator. Any ideas of how to fix this?
Hi Mike, I installed the debug assistant, but now I get the following error:Unable to start debugging on the webserver. Could not start ASP.NET or ATL Server debugging. Verify that ASP.NET or ATL Server is correctly installed on the server.Could you Please let me know if there is work around for this problem.
Firstly, When I installed debug assistant and changing the config file as per your instructions: I got "Unable to start debugging on the webserver. Could not start ASP.NET or ATL Server debugging. Verify that ASP.NET or ATL Server is correctly installed on the server" error. Now, when I ran the app without debugging, I got "Service not available" error. I checked eventlog and saw "debuggassistant.dll failed to load. The date is error" message. I uninstalled debugassistant and installed again and still got the same message.
I am using Visual Studio 2003 on vista home premium, it kip showing this error : Unable to start debugging on the web server. Debugging failed because integrated windows authentication is not enabled.
Unable to start debugging on the web server. The web server is not configured correctly. See help for common configuration errors. Running the web page outside of the debugger may provide further information.
Despite what the error message says, starting the project without debugging won't give you more informations. Luckily enough, the issue is fairly known to ASP.NET developers thanks to many threads on IT resources websites such as StackOverflow. The cause has almost always something to do with the Application Pool used by your web application - usually the DefaultAppPool, unless you've chosen otherwise - which stopped working for no apparent reason.
All of the sudden I'm getting the following error on my local web server (Win7 64bit, IIS 7.5). I've uninstalled & reinstalled IIS locally and it didn't fix it. IIS is set to start up automatically and I can see that the service has been successfully started. Upon a fresh reboot if I go into IIS and click on start website I get the following error:
A Logpoint is a variant of a breakpoint that does not "break" into the debugger but instead logs a message to the console. Logpoints are especially useful for injecting logging while debugging production servers that cannot be paused or stopped.
I'm trying to debug an issue with our website in Firefox. I'm using Visual Studio 2005 SP1, C# and ASP.Net. I've been using this installation for nearly a year with no problems. Yesterday I wanted to debug something in Firefox rather than IE so I changed my default browser to Firefox. I then hit F5 to begin debugging. The build succeeds, but nothing else happens. The debug never begins. Eventually the arrow turns green again so I click it again. The second time I get an error message: "Unable to start debugging on the web server." I click OK and get another message "Unable to start program 'Unable to start debugging on the web server. Click Help for more information.' The specified working directory does not exist or is not a full path."I changed my default browser back to IE, but I get the same errors. I don't know if changing the default browser was the cause because I had not tried to debug that day prior to the change. If I select "Start without debugging," the app starts right up.I've searched the net but have not found a definitive solution. Any ideas?
I was running into this issue in VS2008 after I did a "get latest" out of TFS. VS wanted me to create the virtual directory, although it already existed. I said no the first time, but then the solution wouldn't display in VS. So I said "go ahead and make the directory." After the directory was created I started getting the "Unable to start debugging on the web server. The web server is not configured correctly. See help for common configuration errors. Running the web page outside of the debugger may provide further information" error message.The suggestions above are very complete and thorough, however none resolved my error. For me it ended up being that when the new virtual directory was created automatically through VS, it created an incorrect IIS configurations.There are multiple projects in my solution, and for each one I had to do the following steps:1) right click the project.2) select "properties".3) select the "web" tab.4) ensure that "Use local IIS Web server" was selected.5) change the "Project Url" path to be what it should have been.I also had to reconfigure the IIS settings because of the recreation of the virtual directory. I did the following for each directory created:1) open IIS.2) right click on directory.3) go to "Manage Application"4) go to "Advanced Settings"5) corrected the "Physical Path", as that had changed to something that was not correct.After I did these it worked correctly.

Your "hello world" web page should pop up.If you see the message as "Error while trying to run project: Unable to start debugging on the web server. The machine cannot be found on the network. ..."

I recently faced this issue while I was trying to launch my ASP.NET MVC application from Visual Studio 2017 but I was unable to do that because Visual Studio was always showing me a popup with below error message.
In most cases, users can edit and save the code while debugging without restarting the program.This works with the support of HCR (Hot Code Replacement), which has been specifically added as a standard Java technique to facilitate experimental development and to foster iterative trial-and-error coding.
When you manage a website, it\u2019s almost guaranteed that you\u2019ll run into\u00a0some kind of common issue\u00a0eventually. Websites go down,\u00a0links break, and pages load a little too slowly.

Consider the 405 Method Not Allowed error message, for example.

Next, you will need to choose a destination for the log messages generated by ASP.NET Core. Since the error is happening on a remote web server, you will need some kind of persistent storage like a file, a database, a cloud logging service (like elmah.io), or similar. Let's start with logging to the Windows Event Log by including the following code inside the action provided for the ConfigureLogging method: 2ff7e9595c
