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 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?
What is the right approach when users (authenticated domain admins) should be able to start batch jobs (usually exe files) from an IIS (7.x) aspx (c#) page? This is an intranet site. The batch jobs have to run on the web server as Domain Admins. The website pool is executed by network service or some similar restricted account in AD.
Approaches I can think of (and their disadvantages):
1. Start exe file with System.Diagnostics.Process.Start with another account. This feature is disabled in IIS 7.x, how do I allow it?
2. Create a sheduled task and call scheduled task-api. This unmanaged dll is giving VS compiler warnings because it's unsafe to call from managed code.
3. I suppose there's a better approach, because the previous suggestions doesn't appear safe or robust.
I am trying to register the route collection in .net based on each session. The code I have works fine, you goto website/username and it loads the correct sub pages, but you have to restart the application to goto website/username2 to load those sub pages. But when the application is restarted the second one works, but then not the first one. Is there some way to create a different route collection per session not per application using system.web.routing.
View 3 RepliesIs it acceptable to cache an instance of the database connection on application start?
Looking at the MSDN documentation on thread safety, I quote:
Any public static [...] members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
Given that, is it acceptable/safe for code such as this example below:

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.
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.
I would like to start a System.Threading.Timer in my application when it launches (maybe deploy is the correct word). I have seen that you can use Application_Start() but this is only fired once the first request comes to the application. I need the timer to start as soon as the application is running so that it can check for work to process even if a user is not interacting with the site. How can I get the application to start the timer once it is up and running?
View 4 RepliesWhen 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 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? How do I configure Visual Studio that the WebApplicaton starts in an new instance of Internet Explorer?
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.
Can a datalist be forced to start in edit mode for all records?

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">

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?
