I am not able to debug asp.net application in asp.net 2.0
Whenever I hit F5, it will wait for few minutes then show following message.
Unable to start debugging on the web server. The operation has timed out.
Edit: I also want to let you know that before posting this question I searched a lot on google and find out some key points like restart IIS, register asp.net.
What I was doing, I try to register aspnet_regiis -i by using standard console.
Now I find out that I need to execute vc 2005 command prompt which located under visual studio tools.
Have you tried restarting IIS? Also try and run the application again do you still get the error? And the classic, restart of windows.
With Visual Studio errors like this, you'll often find tons of information by searching on Google, as unsatisfactory as that is, problems like this can originate from something as esoteric as a third party software.
Just a suggestion, Is the port used by the Visual Studio Dev Web Server being used by some other Application?
Also try these suggestions.

Using Visual Studio 2012, suddenly we are getting the error "Unable to Launch the IIS Express Web Server" and the answer is NOT to change the port number, so please don't suggest that. The answer is also NOT to delete the IIS Express folder or the applicationHost.config file ... none of those solutions worked. The only thing that could get any of the programs to run is changing "UseIIS" to false in the .csproj file, while keeping "UseIISExpress" set to true.
<UseIISExpress>true</UseIISExpress>
<UseIIS>False</UseIIS>
If I flip them (UseIIS=true and UseIISExpress=false) it will not run, same error. On a co-worker's PC both values are set to true and that person does not have any issues with running projects. What could be causing this inconsistency and how can we fix this so that we don't have to edit every single .csproj file to get programs to run? We work with over 100 programs so this isn't ideal.
It is hard to pinpoint the problem directly according to an error message. We have to try every solution to troubleshoot it.
This kind of issue happens frequently on the Win7 machine with VS2012.
Lots of people post questions pertaining to this issue on SO, We have to find which solution is appropriate for us.
Unable to launch the IIS Express Web server
On my side, I choose to repair it and run VS with the Administrator account again. It worked perfectly.
Feel free to let me know if there is anything I can help with.
I'm running Visual Studio 2017, version 15.0.0+26228.9
When I'm trying to create a new project via File > New > Project... in Visual Studio 2017, I'm receiving the following error message and the project is not created:
Access denied (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
Don't mind the german message text in the screenshot:
This happens for every project template I use (e.g. C# WPF, VB WPF, C# Console App...).
If I try to create a project via the quick search box on the starting page of visual studio, VS just crashes instantly with no exception message at all:
Has anybody else ran into this issue and might know how to fix it?
I had the same error.
I solved it by following the procedure :
Shutdown all instances of Visual Studio
Delete %LocalAppData%\Microsoft\VisualStudio\15.0_f4938f75\privateregistry.bin file (the ID after 15.0_ may be different per machines)
Start VS as normal user
all credit for this should go to https://developercommunity.visualstudio.com/content/problem/31188/access-denied-error-1.html
Ok, I fixed it.
Long story short, the reason for the problem was an incomplete and/or corrupted setup.
But it was a rather bumpy road to the solution, including several un-installations and re-installations until I eventually figured out why the setup was indeed faulty.
Sometimes I got an exception during the installation, other times it finished just fine, but the HRESULT-error persisted when I tried to create a new project.
I my special case, this was caused by the corporate firewall, that blocked some of the setup packets from being downloaded by the web installer. I solved the issue by connecting to an open WiFi, that's not filtered by the firewall.
As I'm working with a standard user, UAC kicks in when I start any installation routine. When I first started the setup via UAC and connected to the free WiFi, it wasn't able to find the packet servers.
It took me a minute to realize that the admin user I used for UAC had his own internet proxy settings, that wouldn't work with the open WiFi.
After I logged on as administrator, disabled the proxy and logged on as my main user again, I ran the setup again - and it failed again with a bunch of "incomplete workload" messages. As frustrated as I was at this point, I simply ran it again via the "Change" button without even closing the webinstaller and this time it finally completed without any errors!
After this, I could start VS just normally and creation of a new project was possible.
So, if you experiencing any troubles like this, I would strongly recommend to run a "Repair" or "Change" installation just over your existing one but try to avoid any firewalls between you and the internet.
1/ open control panel -> program and future - > IIS Express -> select Repair
2/ Refresh some time -> open Visual Studio
This 's about IIS Express in your computer . you only need to repair it in control panel is ok .
I tried and success.
My solution,
The Clang-format caused this. just disable clang-format:
Options->Text Editor->C/C++->Formatting->General->Eable ClangFormat Support
I had the same error when I tried to create a test certificate.
I have just launched VS as administrator.
And everything is Ok
The below solution worked for me
Make sure all the instances of Visual studio are closed.
Go to %LocalAppData%\Microsoft\VisualStudio\15.0_****
Delete the file privateregistry.bin
I tried changing the version of .Net Framework from 4.0 to 3.5 while creating the project. This solved my error.

When I run my Web API application I get the following window:
It just stays like that indefinantly, until I hit cancel.
When I do hit cancel, this error message is shown:
I have tried rebooting, and running iisreset /restart but it does not fix it.
Any ideas what I can do to get my debugger working again?
NOTE: My Web API 2 project's Servers setting is set to Local IIS. My service is hosted by IIS and when I am not debugging, it works fine.
A possible fix:
Check the "Enable Just My Code" in Tools->Options->Debug
I just did a reset for all the settings for VS and it worked again.
Tools => Import and Export Settings => Reset All Settings
good luck!
I had this issue for Visual Studio 2017 and like with the previous post I had Debugging option "Enable .NET Framework source stepping" ticked. Un-ticking fixed the issue.
So as I commented before I had this same issue, but I now figured out the cause and have a solution.
I just got a new machine last week (this issue was actually one of the reasons why) and after a while I had the same issues, not being able to debug my projects. Luckily because I was installing all the updates one by one I was able to pin-point when it started happening.
It seems the latest update for the "Microsoft ASP.NET and Web Tools" extension breaks something.
Sadly, uninstalling or reverting the Web Tools extension is not easy: Remove this extension by going to the Windows control panel and modifying your Visual Studio installation. I had to remove Visual Studio completely and reinstall it (repair didn't do the trick).
You can update and install all your extensions as you wish, just make sure that you don't update the Web Tools extension
I tested this on my old machine and it did the trick there as well.
I've also created an Issue on GitHub as I won't be updating the extension until this is fixed, if anybody has additional information please add it to the Issue.
In Visual Studio 2015, go to Tools -> Options -> Debugging and deselect "Enable .NET Framework source stepping". This may relate to an issue with loading symbols, so if you want to keep the ability to debug .NET Framework source, then it may help to search the web for how to clear the symbol cache, or preload it, or set your symbol server, and so on.
In Visual Studio 2017, I just restarted my machine and ran the solution, no other windows opened not even a browser, although visual studio took a long time to open (30+ projects in a solution) the problem did not reoccur.
I had the same issue in VS 2017 and un-checking 'Native code' did the trick. Not sure why it was checked.
In my case I set Debugging ->Symbols -> To "Load Only Specified Modules" to include the symbols for, in my case a devops symbols feed for some internal NuGet packages
Options>Debugging>Symbols>Load Only Specified Modules
By checking the option "Always load symbols where located next to modules" the setting won't mess with the regular/classic debugging in VS for your own code
This way the Symbols are still loading where needed and Visual Studio is not trying to load debugging information for all the IIS .net dlls that were loaded by w3wp
Alternatively it can also be configured to not load symbols for microsoft.*.dll and it will also work.
Didn't see this in the current answers, so thought I'd give my 2 cents in 2022:
What worked for me:
Make sure to check that your IIS application pool hasn't been stopped (and restart it if it is), and then if that's not the case, restart your IIS server.
If you don't where those settings are, open our Internet Information Services (IIS) Manager, Application Pools are in the left-hand column, and restart/start/stop your server is in the right column.
I created a new ASP.NET 5 RC1 WebApp using Visual Studio 2015 and published it to Azure. I turned on remote debugging and selected VS 2015 for the debugger. I can attach to the WebApp, but any breakpoint I set is not showing up completely red. Hovering over the breakpoint gives you the message "The breakpoint will not be currently hit. No symbols have been loaded for this document." I did a bunch of searches to see if anyone else had encountered this issue. I found some articles that seemed to indicate the solution:
Remote debugging Azure website: Breakpoints not hit
Azure Website Remote Debugging with git deploy not working
I tried turning off "Just my code" and adding the app setting, but neither of these worked. I even had a colleague try the same thing from his system and his Azure account to make sure it wasn't just an environmental issue on my system. Does anyone know how to fix this?
The problem is the VS 2015 Azure tooling is not yet DNX aware at the debugger level. So for now, you'll need to manually attach the debugger, using the steps documented in this article.
Once you get the list of processes, you'll want to attach to the dnx.exe process, instead of the usual w3wp.
I just tried with a new ASP.NET RC1 app, and was able to set and hit breakpoints. It took a while to attach and load symbols, so be patient :)
I have a solution where i have 8/9 projects.
everything was working good and suddenly, I started to get an error when I start to debug. and it says
Unable to start debugging.
If I close visual studio and run it again, it works in the first try.
and after that it stops working.
In the configuration manager it is set to "Any CPU".
I tried many thing with no luck. Is there any help??
this is how the error looks like..
I got similar error:
"Unable to start debugging. Check your debugger settings by opening
project properties and navigation to 'Configuration properties --> Debugging"
I have solved it by setting :
Properties--> Debugging --> Working Directory
to $(ProjectDir)
As it's an MVC web application, there's a couple of things to check. Firstly, are you sure the web project is set as your startup (this catches me and a couple of others in my office out from time to time)?
Secondly, where are you hosting the project? Are you using Cassini, or are you hosting it in IIS while you debug? If so, check IIS and make sure that the site is started, there's no issues with the AppPool, etc.
Finally, one way to try is to actually press Ctrl+F5 to run without the debugger attached, I often find that IE will then actually display an error that's causing the issue.
