Visual Studio :: Worker Process Crashes, Debugging Not Available?
Nov 27, 2010
I made a small app to capture frame from video using asp.net, in visual studio, it works fine. however the problem arises when i try to use any other servers, I am currently using iis 7.5, and trying to debug on server, but alas when i reach some region of code the attached w3wp.exe just get detached, the process crashs, no debug available anymore.
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've run into a particularly nasty bug where an ASP.NET website attempts to make a call to a WCF service method that sends IIS into a death spiral...that ultimately brings down the associated app pool. It never gets to our log4net code that outputs unhandled exceptions.I was watching w3wp.exe processes spin up and die, so I figured I'd take a dump file on termination using ProcDump from SysInternals using the following command
I have seen this for a long time, and finally decided to put the question up here. I have some applications that I need to maintain that were written in Delphi 2007 for .NET (ASP.NET 2.0). Normally, the first time I run the application (using IIS) I get the classic "Unable to start debugging on the web server. Unable to attach to ASP.NET worker process" message. I simply press F9 (run) again, and it runs. Sometimes I have to try running several times before it will actually run. I am running Windows 7 64-bit (and have seen the same effect on Vista 64-bit). I do have IIS configured for ASP.NET, and I do have the following code in my Web.config file.
The point is that I eventually can run the application in the debugger, sometimes even on the first try. Many times when I get the failure it happens about 15 seconds or so after I press Run, sometimes even after I've hit a page or two (or three) of the Web app. And, yes, when Delphi gets into this mode, I can simply run without debugging, and all is fine (unless I really want to debug). And, I can just keep on trying to run in the debugger and eventually it will just work.
It appears that Delphi's .NET debugger is somehow getting the idea that the application cannot run, and then gives up and stops the process (which as I've mentioned is sometimes clearly running). I know of other developers who have also seen this behavior. My question is, does anyone know how to stop this annoying behavior?
suddenly, with my Visual Studio 2008 I can no longer debugging my web applications (ASP.NET 3.5). I obtain this error: Unable to start debugging on the web server. Click Help for more information. Auto-attach to process [8360] w3wp.exe' on machine 'DELL' failed. The weird thing is that I haven't done special changes to my IIS.
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 run the start debugging option...it runs successfully. but still is shows start debugging option is shown in the Visual studio 2005 IDE. And one more problem is ::I applied break points in one page and run the application. but those break points are not detected....
I am ruuning VS 2008 on Windows XP Service Pack 3. The problem I am facing is that my windows crashes after a blue screen whenever I run a website in VS2008.Its only with websites projects in VS2008 but not with WinForms projects. WinForm applications running without any problem.This happens in this sequence that when I run the project, it starts, debugs and port is opened for my project (a popup that comes right near the system clock in taskbar) and suddenly after that a blue screen comes and Windows restarts. After restarting, a message comes that system has been recovered from a serious, send report to Microsoft blah blah blah...Can anybody figures it out what problem there can be?
I have a .NET infra code running both within the IIS worker process and within a desktop client app. How can the .NET code determine whether it is running within an IIS worker process?
I know that I could check the name of the process (w3wp.exe, for instance), but I would like a more robust approach. I wish to make a side note. This is not a production need. I need this information to enable certain scenarios useful during the development and testing phase. Specifically to ease the testing of secure vs non secure configurations.
Visual Studio (SP1) runs fine until I try and view .aspx source files with the lines
<style type="text/css"> </stlye>
anywhere in them, upon which it freezes (i.e is totally unresponsive) and I have to use the task manager to shut it down.
I have read a lot of questions about Visual Studio 2008 crashing on viewing some source files. However, I still can't fix this problem.
I have systematically deleted and re-included all other code and it comes down to these two lines, which is very confusing. Sometimes it happens as soon as the lines are added, sometimes it doesn't freeze until I build the solution with any of the problem pages open. I can add external style sheets, and it only started recently.
I had Resharper 4.5 installed and have since uninstalled it, and do not have anything else installed.
Also, it happens to other people with the same source code, and re-installing Visual Studio does not fix the problem. So I have several questions:
Is there any way I can find out what's happening? I don't understand how the code (the css tag itself) could crash Visual Studio, and am thinking that this is unlikely and it must be something else within my solution, would this be a safe assumption? Could this have anything to do with installing Office 2010?
I have upgraded a Visual Studio 2005 Web Site in a 32 bit server to Visual Studio 2008 maintaining the same 2.0 framework in a 64 bit server with Windows 2008 R2 Server. The Web Site has several class libraries.
After porting to Visual Studio 2008 2.0 Framework using the Upgrade Wizard, I found that I was unable to hit a break point in the Project code behind files while I was able to in the class libraries. The bin folder has the dlls and the corresponding pdb files for the class libraries. I did start the Web site as an Administrator and made sure whole bunch of IIS7 properties are properly set.
I tried to rebuild the solution as a Web Application in Visual Studio 2008 and gave up that approach as I faced hundreds of error messages pointing to missing references and namespaces inspite of adding whole lot of references and namespaces to the Web.
is there an easy way to debug an application in vs 2008 without actually logging onto my machine as different users? its a winforms app in 3.5 on xp...i know how to do the whole "run-as" option when the program is done and built, but for testing its getting really annoying! maybe something like impersonate that web apps have...anything like that for winforms?
I'm using VS 2010. And in VS 2010 it's even more painful now to attach to the worker process when you want to test your local IIS site via IIS, not the VS built-in web server.It's more painful because now when you select the worker process () via the Debug Menu | Attach to Process | w3wp.exe it brings up an additional prompt asking if you're sure you want to do this.
I have increased the number of worker process of default application pool to 15(IIS->Application Pools->DefaultAppPool->Properties->Performance->webgarden).after increasing the worker process i am facing session timeouts
My application is using a state server session managemnet and a predefined machineKeyCan you please guide me in how to increase the worker process without session loss
I have a site that I am developing with VS 2008. I have a breakpoint set in my code behind file. This file is vast as some of it was created with Iron Speed 7.0. What I'd like to do is limit the debugger to the one file. That is, no matter where the code goes it skips over code in other files, and automatially breaks when execution returns to the file I put the break point in. The code is too vast to step a bit at time and choose to step into or out of bit of code. I want it to just debug the current file.
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 want to edit my code while debugging. Some projects i am able to work but in some rojects i am not. When i edit my code I got the following error:"Changes are not allowed while code is running or if the option "Break all processes when one process break' is disabled. The option can be enabled in Tools, Options, Debugging."I tried to do as per the above instructions but still i am getting the same error. Any one know the solution plz help me. By the way i am using Windows application and using VS 2008
I want to use the web.config transformation that works fine for publish also for debugging.When i publish a web app, visual studio automatically transforms the web.config based on my currenc build configuration.How can i tell visual studio to do the same when i start debugging.On debug start it simply uses the default web.config without transformation.
