I have been developing asp.net web sites using MS Visual Studio 2008 on Vista home premium 32-bit OS on my laptop but recently, when I start debugging asp.net pages, "Page not found" error is occurring. I have tried a lot but I couldn't solve the problem.

Hi
When exactly does this error occur? Can you at least start the web app or does the error occur when trying to access a specific page?
The error occurs for all web pages that i have done before. It was working fine for all web pages but now even i can't debug a single simple page.
Thanks
you are creating filesystem website or local iis website, which type??
Are you using Cassini (the IIS built into Visual Studio) for debugging?
Or are you using a real IIS?
If you're using Visual Studio for debugging then you have to run Visual Studio as Administrator (right click on it and run as administrator) or else debugging will not work. You can configure Vista to always run Visual Studio as administrator.
If you're not using Visual Studio to debug, and you're trying to run the website from IIS then your IIS is either not configured properly or the files that you're working with do not exist in the location that IIS is expecting them to be.
If this is the case, did you publish the website to the folder where IIS is expecting the files to be?
I can't help you until you tell us more about your configuration.

I am using the IIS built into Visual Studio for debugging and I have run also Visual Studio as Administrator, but the problem is still not yet fixed.
Are you using MVC ASP.NET ?
The only time I've ever seen this type of error was when I missed typed the name of the Controller that I wanted to use.
No, I am not using ASP.NET MVC. I am just using the traditional ASP.NET web forms.
Go to your Solution explorer and right click on one of your aspx pages.
Select "Set As Start Page".
Then try debugging....?
I did that several times, but the result is the same.
Open a new instance of Visual Studio and create a new project.
Add some text to the default page and hit the debug button....does it work?
No it doesn't work. I did that too several times.
I'm not sure what to suggest at this point.
I use Vista sometimes while I'm developing and I've never run into that problem. The only problem I've ever had debugging on Vista was when I wasn't running as administrator...but it still ran (the page was found and displayed in a browser)...just that it never stopped at the debugging statements because I wasn't running Visual Studio with the appropriate permissions.
I'm sorry but I have a feeling you're going to have to uninstall and reinstall Visual Studio.
Thank you very much,
The problem is really strange. I will try reinstalling Visual Studio.
Greetings
Uninstalling and reinstalling Visual Studio didn't work out.
Is there something you installed or uninstalled prior to this problem? Anything at all? Perhaps you can (and I don't know if this is an option in Vista) do a system restore to a point that everything was working fine?
Steven
I couldn't get a restore point in the System Restore where everything was working fine.
Yes, I did install Anti virus and Blaze Advisor for .NET which is a business rule software, prior to the problem. But I have tried debugging after uninstalling these software, the problem was the same.
Even though I tried a lot of fascinating ideas from various experts, the problem yet not solved. Is there anyone who can give the last and best idea before I format my computer.
Thanks
