In .NET 1.x itself we used to face the similar issue. Check out http://vadivel.blogspot.com/2006/05/error-while-trying-to-run-project.html

Another possibility is the project settings. Check "Debugging, HTTP URL" and verify that this entry is in fact where you've deployed your project on the webserver. The debugger is typically going to look for the .asmx file in the localhost/solution/project/project.asmx as opposed to localhost/project/project.asmx unless you change this.

It hasnt work for me.. i still have the problem..

I mean .. im using .NET 2.05... and Visual Studio 2005 and IIS 6 with Windows 2003 Server...

Hi, Got the same problem, and this what i did, if you have multiple projects in your solution, pls checked your IIS if all the project has same ASP.Net Version, hope this would help.

Still have same problem. I have VS 2005, IIS 6 & Win 2003 Server.

I have this problem too and solve it.

You need to make your web application to use integrated windows authentication. Second thing, you also need to have a web.config file that stated <compilation debug="true">

Hope this help.

Yet another possibility is that the solution may be setup to start debugging on the active project, which might be a class library. If that's the case, just click the name of the project you want to debug and press F5 again. You may also want to consider setting a specific project as the default, but this isn't always possible.

It is not woiking for me...

nOOOO, its not working for me either, done all 3 things

register aspnet account with version surely it will work

In my case I needed to give the Network Service account full access rights to the "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files" directory.

This will surely work...

1. Right click on the folder - "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files".
2. Select 'Properties'
3. Select the tab page - 'Security'
4. Click on 'Add' button
5. Click on 'Location' button
6. Choose your computer name.
7. click OK button
8. Click on 'Find Now' button
9. From the list, select 'ASPNET'
10.Click OK.
11. Now check the check box - 'Full Control'.
12. Click OK
13. Start debugging ur application

Nice try Satish. Unfortunately, none of the above have worked for me, including your suggestion. Anyone else?

NOTE: I didn't have this problem until I installed the ASP.NET starter kits that I got from www.asp.net. Did anyone else have this issue soon after installing the starter kits?

Tried most of the above to little avail. Lastly I gave full access rights to the 'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727' folder and full access rights to all web project folders in my solution. Finally I ran the aspnet_regiis /i tool located in the 'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727' folder.
And now it works again! What exactly did the trick? I don't know, but maybe these steps work for you as well.

Kind regards

Tried all the above but couldnot get any success. I am trying to run my apllication on a different port (8080) as on port 80 already sharepoint portal 2007 server is running. I wanted to run both at the same machine but i am doubtful about the starter kit as i have also installed it.

Guys..none of the suggestions given works.Wht to do?

The trick was - that you've installed your IIS server after installing ASP.NET. So you had to register IIS manualy. Although, it didn't help me much =)

Just close VS2005 and delete all temp files in C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files

Guys ...i have tried all the above option but nothing is working.Plz suggest something different.

Ok, I was having the same problem and I just fixed it...here is what I did:

1) Go to Internet Information Services
2) Right mouse click on your project directory
3) Go to the ASP.NET tab
4) Click the Edit Configuration button
5) Select the Application Tab
6) Check the 'Enable Debugging' checkbox

That's what worked for me

none of the above solution is working for me ...any other way out ???

None of them worked any thing else please?

Ok, try this:

Do EVERYTHING mentioned above including the "aspnet_regiis /i because that was the final thing for me after I did everything plus the stuff below:

Internet Options
Security
Trusted Sites
--- Add the following:
http://localhost
http://127.0.0.1

Me again - you MUST make sure you do everything mentioned above - I did it all and then the internet options thing - and nothing worked until I read the part to run:

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis /i

once I did that - BOOM - it worked. You have to set all the security things up, etc, etc - application name, asp.net version in iis, all that - I hope it works because it did for me and I was about to throw my computer out the window...

Okay I fixed the problem by doing this:

-Go to IIS
-Hit properties for the website
-Hit Asp.net tab
-Hit Edit Configuration
-Hit Application Tab
-Select C# as default language

*For some reason my default language was set to vb. All my code is written in C# not vb.

Hi all,

I've fixed this problem with these steps :

Right click on your project in VS2005.
Click on Properties
Click on Web tab
Under Servers, click on the radio button Use Visual Studio Development Server
Check Auto Assign Port radio button
Uncheck NTLM Authentication and Enable Edit and Continue

It works for my case

Hi all,
i was facing same issue when i changed my project from 2003 to 2005 and i solved my problem with these steps:


Right click on your project in VS2005.
Click on Properties
Click on Web tab
Under Servers, click on the radio button Use Visual Studio Development Server
Check Auto Assign Port radio button
Uncheck NTLM Authentication and Enable Edit and Continue

HI,
PLZ HELP ME. I TRIED ALL THE WAYS U HAVE LISTED. I WAS NOT ABLE TO CORRECT IT.

My asp.net is not running because of web server is not running

try running this command
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis -i

Hi,

running the aspnet_regiis /i command worked for me aswell.

Thanks

Hi all

Ok if all the above fails then try this (it's the one that worked for me):

Go to IIS and right click on the 'web site' and go to 'properties' and select the 'Home Directory' tab.'' Under 'Execute Permissions', if it's set to 'none' then change it to 'Scripts and Executables'.

Restart IIS and fingers crossed!!

Within Web config look for <compilation debug="false"> and set this to true.
Sorry if someone has already mentioned this before.

Most of stuff is rubbish, neither solved my problem

Hi, this worked for me when I did all the steps above and additionally opened IIS manager, right clicked on default web site, made sure the tcp port is 80, vent to asp.net tab and set the version to 2, the choose "Edit Configuration" button and select Application tab and check the "Enable debugging". Restart IIS.

ok one more thing, I was working on a site that required ssl, and had set "Require secure channel (SSL)" once I unchecked that I can debug again.

Set the permissions on the folder for your logged in username.

I have this problem while registeering aspnet_regiis

IsDomainController failed with HRESULT 80070842: 'The Server service is not started. '

anyhelp?

Thanks

Right click on the project , choose property pages then go under Start Options and under Debuggers check you should have checked only the Native code checkbox....this works for me

I've tried all of the above...several times...did a repair install of VS 2005 and nothing...its dead...I also tried opening IE and attaching to it as a process...no go there either...very frustrating and renders my project useless. I can get the site to open fine...just not with the debugger on....I'm screwed

Did try it all out.
The only thing working was:
running the aspnet_regiis /i

I had this problem when setting up a new development machine, and then remembered that I need to add the following line to the machine.config file:

<compilation debug="true" />

I added this right underneath the <system.web> tag, directly above the <processModel> tag. It fixed my problem.

machine.config is located in the following directory on my machine:

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG

I've been having a similar problem and found these posts to be helpful in isolating it. In my case, I had to edit the project settings as follows:
1. under the Start Action section, specify "Specific Page" and list your startup page. Should be the same as the Default Page setting in IIS.
2. the Servers section should specify "Use IIS Web Server", and under that, "Project URL" should specify the fully qualified Project URL. This includes "http://<machine-name>/<project-name>", where <machine-name> is the machine name for the local web server, NOT localhost. I tried localhost and it did not work.
3. Set the Debuggers section to ASP.NET, and save changes and rebuild, then start in Debug mode and you should be good to go.

I am using visual web developer 2005 express, on windows vista ultimate, I first went to control panel, then programs, then turn windows features on or off, then I set all the correct settings under Internet Information Service, making sure Windows Authentication was selected. Then in IIS Manager I set Windows Authentication and Anonymous Authentication “enable”, next I right clicked on Default Web Site and selected Advanced Settings, then under Application Pool, I set “Classic.Net AppPool” and everything worked out ok.

I solved the problem, thanks.

This situation occurred because I changed my web server setting from development server to IIS.

Why did it not happenned on development server? Weird.

What is the reason ASP.Net tab never appears in my IIS.MSC anybody know?

running the aspnet_regiis /i command worked for me aswell.

running the aspnet_regiis /i command worked for me as well.
Please perform other steps suggested.

Enabling debbuging in Configuration of the ASP.NET tab worked for me.

Thanks Brian

If you are changing anything in IIS or anywhere else while your Visual Studio Editor is opened, remember to close and reopen the Visual Studio editor to make the chages enabled in the environment. Those who cannot recover from the error after doing all these steps can try this.

I did everything said up there nothing worked, but this worked for me:

1- Open your yourproject.csproj file in Notepad
2- Make sure your project namespace and assembly name are correct in <AssemblyName></AssemblyName> and <RootNamespace></RootNamespace> tags.
3- Make sure <IISUrl>http://localhost/yourproject</IISUrl> is correctly pointing to the application name you specified in IIS

They weren't correct for me, so I changed it and saved the file , and F5-ed it, and what a pleasant surprise.

running the command
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis -i
worked for me thanks a lot fish,scott and vishal

I was slamming my head against a brick wall for hours with this same issue.

It turns out, somehow permissions specifically on my web.confif file had got messed up. once i gave my machine and aspnet accounts full control the problem was solved.

So i'd look a little deeper than just the iis/directory level with the permissions things as it seems that they are generally somewhere at the root of the problem.

aspnet_regiis -i worked for me as well.

I tried everything here till about halfway down the page before i just resorted to reinstalling the framework.

Many thanks to whoever initially figured out the fix!

Make sure your web.config file is proper. I had a problem in which I had duplicate attributes on a node....

the problem on my pc was, anyone deleted the complete Inetpup folder.

you just have to create the following folder structure:

c:\Inetpub\wwwroot\aspnet_client\

Error:

"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."

SOLUTION: START->RUN->CMD ENTER-> Type the following

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis -i

mine used to work but now it has the same problem as above.
i tried all but this one really helped me:

Log onto the Web server using an administrator account.
From the Start menu, open the Administrative Tools Control Panel.
In the Administrative Tools window, double-click Internet Information Services.
In the Internet Information Services window, use the tree control to open the node named for the Web server.
A Web Sites folder appears beneath the server name.

You can configure authentication for all Web sites or for individual Web sites. To configure authentication for all Web sites, right-click the Web Sites folder and choose Properties from the shortcut menu. To configure authentication for an individual Web site, open the Web Sites folder, right-click the individual Web site, and choose Properties from the shortcut menu
In the Properties dialog box, select the Directory Security tab.
In the Anonymous access and authentication section, click the Edit button.
In the Authentication Methods dialog box, under Authenticated access, select Integrated Windows authentication.
Click OK to close the Authentication Methods dialog box.
Click OK to close the Properties dialog box.
Close the Internet Information Services window.

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis /i

Run this and it should work fine..thanks

Hi All,

Thanks! This worked for me too. :-)

Go to IIS and right click on the 'web site' and go to 'properties' and select the 'Home Directory' tab.'' Under 'Execute Permissions', if it's set to 'none' then change it to 'Scripts and Executables'.

Check Auto Assign Port radio button
Uncheck NTLM Authentication and Enable Edit and Continue

It works for my case

Hi all,

I have tried every single step from the above, and i restarted my pc couple of times... even tried to restore windows to earlier checkpoints but nothing seemed to work... I've reached a point where i thaught i should format my pc and install everything all over again...

But, i remember that i did something last week in:

I unchecked the "HTTP Keep-Alives Enabled" because i was testing the server under heavy pressure, so the debugger worked when i re-checked this option.

To check this

1 - Open IIS (control panel > administrative tools > internet information services)
2 - Right Click on Default Website choose Properties
3 - Under Connections: make sure the button "HTTP Keep-Alives Enabled" is checked
4 - Click on OK
5 - Check your debugger.

hope this helps
