Installation :: IIS - VS2010 - Configuration Error "Unable To Start Debugging On The Web Server"
Dec 1, 2010
I'd installed newly Visual Studio 2010,and i want to create a new local website on my iis server and i follow these steps:
1-from my iis i create a virtual directory
2-in command promt i execute these commands:
aspnet_regiis -i
aspnet_regiis -ga aspnet
3-i go to VS2010 and create a new website (HTTP) and choose my created Virtual Directory has been built in previous step
Now if i do step 3 with framework 4 i don't have any problem but with framework 3.5 my website hasn't been run and says me : "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."
I get error message "Unable to start debugging on the web server" in Visual Studio 2010. I clicked the 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 am getting this error, without any further details, when attempting to debug my ASP.Net project in VS2010. There are other developers using the same tools and code who are not having this problem therefore I know the problem is not in the web.config file. I have found several suggestions when googling the issue and tried them all to no avail. I uninstalled and re-installed VS2010 along with the .Net 4 framework. I made sure Anonymous as well as Windows authentication is enabled in IIS. I uninstalled and reinstalled IIS. I am at a loss. I can attach to the process and debug the ASP.Net code that way, but what I really need to be working on is a Silverlight app that is called from the ASP.Net and the breakpoints don't work in Silverlight when I attach to the process manually.
I am running Visual Studio 2010 (as Admin), IIS 7 on Windows 7 x64. I am able to run the ASP.NET web site in IIS 7 without debugging just fine, but when I press F5 to debug it, I get: Unable to start debugging on the web server. Could not start ASP.NET debugging. More information may be available by starting the project without debugging. Unfortunately the help link is not helping me much and leads down a heck of a large tree of things. I checked the following:
Security requirements — I don't recall having to do anything special before. The worker process in IIS7 is w3wp.exe. It says that if it's running as ASPNET or NETWORK SERVICE I must have Administrator privileges to debug it. How do I find out if I need to change something here? Web site Property Pages > Start Options > Debuggers > ASP.NET is checked. Use custom server is set to the URL of the site (which works fine without debugging). Debugging is enabled in web.config. Application is using ASP.NET 3.5 (I want to move to 4.0 eventually but I have some migration to deal with). Application pool: Classing .NET AppPool (also tried DefaultAppPool). Surely it shouldn't be that hard to install IIS, VS, create a web site, and start testing it?
I am trying to run my application on IIS 7 and Windows Vista Home Premium. I am getting the following error "Debugging failed because Integrated Windows Authentication is not enabled". How do i resolve this issue?
I am getting an error "Unable to start debugging on the web server..." while running as web application in VS2005. But the error seems only for this application. I created a test application, both in VS2005 and VS2008, and found no issues in running these applications.
I'm trying to debug an ASP.NET webapp that's configured to "Use Local IIS Web Server" on WinXP. When I start the debugger, the compile succeeds, and then the following error is displayed in a dialog:
Unable to start debugging on the web server. The COM+ registry database detected a system error
The webapp never launches in my browser. How can I get rid of this message and debug this webapp?
I get this error when I hit F5 in VS 2008. I have checked that Windows authentication is enabled on the site and it is. I can mannully attach the debugger to the IIS process and it works. What could be wrong? I have tried alot of things without success.
I'm trying to debug my web application on my localhost machine in Visual Studio 2010 and I keep getting this error: "unable to start debugging on web server. The Microsoft Visual Studio remote debugging monitor(MSVSMON.exe) does not appear to be running on the remote computer."
Is there a way I can turn this off as I'm not trying to make any attempts debugging remotely.
I tried to run my WebApp on my local machine today (nothing has changed on it) and I had the above error. I know my machine had a windows update recently (not sure if that has anything to do with it).
The error produces a big print out of css styles and html markup.
In the markup it also says "The requested page cannot be accecssed because the related configuration data for the page is invalid".
I was working away just fine on my ASP.NET 2.0 application (Win7 64 bit, IIS 7.5.76) when all of a sudden I get a pesky error message "Unable to start debugging on web server" when I start the app in Visual Studio. The error message (attached) is HTML text and is so long that I can't even get to the bottom of it to see what the punchline is. It happens with debug switched on and off.
I installed vs2003.net on sbs2003 with IIS6 (.net framework 1.1) I created my first app, put a label on webform1 and run the project (debug)
1 - messagebox: "Error while trying to run project: unable to start debugging on the web server. The project is not configured to be debugged (I did a lot of searching, found tons of so-called solutions, but neither works)
2 - run the project from the menu Start without debugging. I got a server-error: <authentication mode = Windows in web.config)
Two questions:
a. when the app runs under VS.2003 it uses IIS ?
b. if not, why doesnot run the app ? if so, which website it uses in the IIS-manager (is that the Default website or other ?). What happens when I delete all the websites in IIS-manager and run the app in VS2003 ?
I am trying to update an old VS 2003 Web project. I've worked on it plenty of times in the past on this machine with no issues, but for some reason now when I try to debug it I get the above error (Unable to start debugging the web server. Access is denied.) ANybody have any thoughts on what might cause this?
I am having issues debugging locally within Visual Studio 2010 on Server 2008 R2 (x64) for a new ASP.Net MVC application. I am able to debug using the VS Development Server (Cassini) but when I change to use the Local IIS Web Server and Create Virtual Directory, I am unable to debug. I get the standard VS message:
"Unable to start debugging on the web server. The web server is not configured correctly. ..."
Everything looks standard in IIS. The Default Web Site is running under the ASP.NET v4.0 application pool. The virtual directory that Visual Studio created is running under the same app pool. I am running Visual Studio as the Administrator account. It feels like some security setting or something is preventing this to work but I'm at a loss to what it could be.
I used to have nice development environment at XP for .Net web application development. I have now installed Windows 7 and going to take it as my new machine. I already installed VS2005 and I'm able to build a project. IIS is working fine and I'm able to open the web application in the web browser. Windows firewall is Off.When I click Start Debuggin on Visual Studio 2005 on Windows 7 I get following error:Unable to start debugging on the web server. Unable to connect to the web server. Verify that the web server is running and that incoming HTTP requests are not blocked by a firewall. What could be wrong? Something to configure in the IIS?
Unable to start debugging on the web server. The IIS worker process for the launched URL is not currently running.I'm running Windows 7 64 bit, VS 2008 sp1.When I first try to debug I get the error msg above. I wait a few minutes (presumably some service is starting) and debugging will start but no breakpoints are recognized.Some of the things I've tried:Changing the binding of my site from a static IP to "*".
Enabled windows authentication.made sure localhost = 127.0.0.1 in the hosts file.The website was built under windows xp and whatever version of IIS ships with xp. My web config has no errors that I know of but might be missing something required for iis 7 (??)
I have used Visual Web Developer (versions up to 2010) with no problems for several years. Starting last week I am no longer able to run or debug any ASP.Net application locally. I am running Windows XP, IIS 5.1, IE8, Visual Web Developer 2005, targetting .Net 2.0. I am not able to Start Debugging or Start Without Debugging for any project. When I attempt to Start Debugging, IE browses to [URL] instead of to the project I am attempting to run. When I Start Without Debugging, IE opens to about:blank and then when I close that window another IE window opens to [URL]
Maybe irrelevant, but I had the same problem with IE7 and VWD 2010 (versus IE8, VWD 2005). IIS is set to .Net version 2.0. I have the same problem whether I add a virtual directory to my project in IIS or not.
I just started getting the error message "Unable to Connect to the ASP.net Development Server" when debugging a website with VWD 2008 (everything was fine in the past). My system is Windows Vista with Windows Live OneCare firewall. I have reviewed other postings related to this problem, and they indicate firewall setting problems - settings not allowing VWD internet access. However, my settings on the "Windows Live OneCare Firewall Advanced Settings" tab specifically allow VWD.
I've got two sites hosted on a win2008R2 box that I just moved to .net 4 from 3.5. One worked well, but the other is showing a 500-internal server error on the server. It builds fine in VS, and runs fine in Cassini.I've changed the app pool to .net 4 and copied the new web config into the site, but I still get an error. I did this about a month ago with another site and everything worked fine.I can't use my own error logging code because my app doesn't even get started, and IIS doesn't seem to leave anything in the application event log. Apologies in advance for a dumb question, but where can I get some more detail on this error?500 - Internal server error.There is a problem with the resource you are looking for, and it cannot be displayed.

I have OS windows 7(64 bits), Visual studio 2008 and Oracle 11g I have run "InstallAllOracleASPNETProviders.sql" who comes with the Oracle installation. When I run in debug I can run this application, but not otherwise. And in IIS manager, I can't se the Oracle provider?

If application is started without debugging - it runs smoothly, when I press F5 I get: "Unable to start debugging on the web server. Could not start ASP.NET debugging. More information may be available by starting the project without debugging. Click Help for more information"I noticed that problems are caused by URL Rewrite section in web.config:
when I comment it out - I can start debugging. Also debugging works on VS's built-in web server.I'm running Win7 64 bit, VS 2010, application's framework is 4.0, in IIS application has ASP.NET 4.0 Intergrated pool set
