I have IIS 5.1 on a XP machine, and visual studio 2005. How do I go about attaching my debugger to IIS instance.
BTW: I'm not seeing the IIS process within the running processes or probably I don't know what to look for .
In Visual Studio:
Click "Debug" from the menu bar
Click "Attach to Process"
Check the "Show processes from all users" checkbox in the bottom left corner
Select aspnet_wp.exe, w3p.exe, or w3wp.exe from the process list
Click "Attach"
Just to clarify Jimmie R. Houts answer…
If you want to debug the web application VS and IIS you can do the following:
Host the site inside IIS (virtual directory etc).
Then in VS2005 do this:
Right Click on Web Project → Properties →
Start options → Use Custom Server → Base URL → Enter Site Address as
Hosted in IIS.
Hit F5 and you will be able to Debug your code
Same works for VS 2008 also.
I'm running Windows 7 with IIS Version 7.5 and I also needed to tick the "Show processes from all users" and "Show processes in all sessions" boxes - at the bottom of the "Attach to Process" dialog.
Also I had put my app in a specific App Pool which means you can then see it labeled against the w3wp.exe.
The possible names of the ASP.NET process:
w3wp.exe is IIS 6.0 and later.
aspnet_wp.exe is earlier versions of IIS.
iisexpress.exe is IISExpress.
dotnet.exe is ASP.NET Core.
inetinfo.exe is older ASP applications running in-process.
From Find the name of the ASP.NET process
The IIS process is aspnet_wp.exe.
In fact, attaching to the aspnet_wp.exe process is what VS does when you have your project set to use IIS for debugging.
You'll also need to open Internet Information Service From Control Panel > Administrative Tools. Right click the web site in question, click the home directory tab, and select the configuration button. This will open a new form with three tabs - click the debugging one and select the two options in the debugging flag section. This is also necessary to debug.
Using an Attach to IIS plugin (VS2015, VS2017) plugin saves a few clicks - especially when dealing with an ecosystem of IIS hosted sites (one frontend with multiple backend services say)
If you see the process [e.g. IIS Worker Process (w3wp.exe)] running is Task Manager, but not in the list of processes in debug > attach to process, you might need to run Visual Studio as administrator.

I am trying to run a specific Web Project in a way to receive requests from an external application.
So when pressing F5 it starts the current Web project in visual studio with debugging but waits from the other site for web calls.
The problem is that for the other web site to work i have to launch several other sites, with services, resources, auth server etc. Some are not part of the solution - which means I cannot use "Always launch when debugging".
For that I have the executable that you can see grayed out in the "Start external program" section. The "IISExpressRunner". This program will also open the site that will access this one after everything is setup.
My problem is that I currently need to run that manually every time I start debugging because both options cannot be selected at the same time - which of course does not make sense since it can debug only one thing.
I can debug the WebSite via the IISExpressRunner application alone, however that has the implication that I need to run VS in Administrator mode, since the app requests UAC to be able to disable IIS to run IISExpress on port 80 - specific for domain alias and authentication server redirects for Google and Facebook logins - to be able to run it locally in the dev environment.
So is there a way to have Visual Studio debug the current project and automatically after debug has started to also execute this external application without debugging it?
A workaround I could think of is that you could call the bat file before you debugging the app using code "Debugger.IsAttached()".
Run batch script before Debugging
There is a manual process you can use. During running a debugging session, right-click the project you want to also start debugging, go to the Debug submenu, and click Start New Instance.
I have an application solution consisting of eight projects in C#/.NET with Web services.
One of the projects is of web services.
All the data is fetched through the web services in a Windows Forms application.
But while debugging my Windows application I am unable to debug the web services called for fetching the data in Visual Studio 2010.
How do I debug a web services project in a solution when data fetching events are fired?
Normally, when debugging in Visual Studio the selected StartUp project will be executed in debug mode. In your case you need to start and debug both the Web API project as well as the WinForms project. You can do that by right-clicking in the solution explorer and selecting Set StartUp Projects. A dialog box opens where you can select Multiple startup projects and then select which projects to start when debugging the solution.
Another option is to have a single StartUp project (the Web API project as this is a requirement for the other project to run). You can then right-click on the WinForms project in the solution explorer and select Debug -> Start new instance. You can do this multiple times to debug multiple instances of the same project.
Obviously, you can always attach the debugger to any running process and if your Web API is deployed using IIS it will already be running. Using the procedure outlined above Visual Studio will attach to the right worker process.
You should attach Visual Studio to the host process of your web service.
This process is usually the IIS worker process which name is w3wp.exe on IIS 6+ on Windows Server 2003, Vista , later.
To attach to this process, you can use Debug -> Attach to Process in visual studio. Inside the Attach to process dialog box Make sure you've checked the Show processes from all users and also when selected your process, make sure that Managed code is selected. To select managed code click Select... and check the Managed Code checkbox (V2.0 or V4.5,4.0 depends on your selection of framework)
You can debug the web service by attaching the VS debugger to a process as follows:
Debug > Attach to Process > Attach
You can browse the available service that you are looking for and attach.
You can attach to the process of your web service. In Visual Studio, click menu Debug → Attach to process.
This writing is 2019, solution is to attach to IISExpress. Debug -> Attach -> find iisExpress (not the tray) in the list, .
I have a web site being hosted on a Windows Server 2012 using IIS8. I had modified some code and uploaded it to the server and then restarted the website. The problem is, the old code is executing!
I have:
Restarted the IIS Server
Rebooting Windows Server 2012
Disabled Output Caching for the site.
Disabled Output Caching for the entire server
Removed and readded the website.
I even opened the code file in notepad on the server and confirmed that it IS the new code. The old code, to my knowledge, doesn't exist on the server! What am I missing?
You may want to try attaching the visual studio debugger to the instance of IIS and see if you can hit some breakpoints in the old/new code.
To Do this in visual studio.
Click "Debug" from the menu bar
Click "Attach to Process"
Check the "Show processes from all users" checkbox in the bottom left corner
Select aspnet_wp.exe from the process list
Click "Attach"
If the code does not match between the code in visual studio and the code, you will not be able to set a breakpoint. However, if the code is the same, you will be able to attach and breakpoint and follow the flow of the execution.
Also, have you checked if the DLL's are deployed to the GAC (Global Assembly Cache)? If a .dll exists in both locations on the windows box the application will always pull the version that is in the GAC.
Am trying to debug the web application hosted in windows server 2012 with IIS 8.0. I opened VS2008 with the code and i Attach process but no W3Wp.exe process is listed there.
In task manager i can see the w3wp.exe under details tab not in Procees tab. In process tab IIS worker Process is listed.
Checked all users and all sessions as well
Please let me know how i can debug.
Thanks
Ticking 'Show processes in all sessions' showed it for me
While creating the website I choose Location as HTTP and then provided http://172.24.17.188/myProject and it created the project happily.
And I was able to run the project too. But once I have closes the VS2008 and reopened the project , I am getting the following error while trying to run the website.
Edit:
I am able to browse the website by manually typing in browser but unable to run or debug usinh VS2008.
If the website is running on IIS on the same machine then you can attach the debugger to the IIS process. You do this by click on "Debug" then "Attach to process...". Sort the processes in descending order and find the process named "w3wp.exe". Then click the "Attach" button. If you don't see the process then view the site in a browser to allow IIS to start the process.
If the website is running on a different server then you can do the same but you need to run the remote debugging tool (MSVSMON). This means you will need to have Visual Studio installed on the webserver. Run MSVSMON and be sure the firewall doesn't block the connection. Now you click "Debug" then "Attach to process...". Enter the server name that was displaed on MSMON's debug window in the qualifier textbox. If everything is setup properly you will see the remote servers process list. Then you can connect to the "w3wp.exe" process.
These are two ways to debug web applications using Visual Studios and IIS.
Do the following changes in your IIS settings
Make sure that IIS is configured to use Integrated Windows Authentication
Make sure that HTTP Keep Alives are enabled.
