When I run my project from Visual Studio, my webpage comes up normally, and about 5-10 seconds later, a duplicate one appears as well. (not that hard to close the second one) I just thought I'd ask if anyone knows why it would do this.
By the way: It only seems to do this when I already have a browser window open (not including my project's webpage browser window).
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?
When debug a project, then error message show:
"Error while trying to run project : Unable to start debugging on the web server. The project is not configured to be debugged."
Debug-Start Debugging/Debug-StartWithoutDebugging OR Project ASP.Net Configuration launches Dreamweaver. It started lastnight, I had both Deamweaver and VWD 2008 express open at the same time - (I was looking at JQuery in the Microsoft and Dreamweaver enviroments simultaniously). After the first tie this happened, I closed down Dreamweaver (CS3) and it opened when I tried to run my VWD project. I reinstalled VWD 2008 express, IIS and disabled Dreamweaver (renamed the exe). Dreamweaver still came up.
View 4 RepliesI 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.
View 2 RepliesI'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.
In our ASP.NET application we perform some initializations upon the Application Start event.When the application is started in visual Studio 2010 with 'Debug->Start new instance' the ASP.NET Development server does not start new, and my Application's Start event is not fired.My workaround is to manually stop the development server - is there a setting to force this automatically?
View 1 RepliesI am currently write an ASP.NET WebApplication in Visual Studio 2010. My default browser is Firefox. If I start an WebApplication, the WebApplication starts up in the same instance of Firefox. How is it possible to avoid it?

View 2 RepliesI 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'm using VS .NET 2005 in windows 7 and when I run my Web project it Appears the Error as Image bellows:
In my IIS 7 I haved setup all requirments for IIS7 as image bellow:
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.
View 3 RepliesI 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?
View 13 RepliesI 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 do have Resharper V5 installed.
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?
View 4 RepliesI have a solution I have been working on over the last few weeks with a 3 or 4 projects in that used to build and begin debugging in under 10 seconds.The solution contains 3 dll's and 1 mvc project.
As of today, it takes about 2 minutes to start debugging, it keeps pausing on "loading symbols for ccpCodeProvider.dll".
I'm debugging on the internal vs development server, and I haven't changed anything since yesterday?I haven't ever used symbols before, and I'm not trying to debug the framework or anything, I just want my stupid web project to run.I created a new solution from scratch and added a random console app, and that also takes forever to debug.
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.
View 1 RepliesI 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?
I have application developed in vs 2005, when i try to run it throws below error.
"Unable to start debugging on the web server. The underlying connection was closed: An unexpected error occurred on a send."
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:
<rewrite>
<rules>
<clear />
<rule name="LowerCaseRule" stopProcessing="true">
<match url="[A-Z]" ignoreCase="false" />
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
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?
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 put a breakpoint on a Page_Load method for a .aspx page and I'm getting the following error when trying to run in debug mode:Quote:The breakpoint will not currently be hit. No symbols have been loaded for this document.I checked the "Modules" window and the DLL for this project is not listed there, but it does list all the DLLs for the other projects in the solution. I also checked web.config and verified that debug="true".
View 5 RepliesI have two projects: A web application project, that has a webpage that hosts a Silverlight application, as well as a web service A Silverlight application project, the one hosted in the above web application
If I debug the Silverlight application, it wants to run this with a generated web page, which will of course not start my web application, and web service calls fails due to some cross-site security model. So even if I have the web application running, the Silverlight application won't use it.
If I debug the Web application (that is, set it as a start project and hit Debug), then the Silverlight application is apparently correctly hosted, but I can't debug it. Any breakpoints in it shows up as those hollow circles.
So what am I doing wrong? How should I configure my projects so that I can start the web application, host my Silverlight application, and debug it?
I'm betting it is one of those "dough" moments when someone tells me, but I can't figure it out.
This is Visual Studio 2008, .NET 3.5 and Silverlight 3.
Is it possible to debug a Web Setup Project, specifically its custom action code, by setting breakpoints and walking through the code? How does one do this?
