I'm in a need to get a list of all the ASP.NET running worker process and its associated application pools and process ID.

Is there a way to do this pragmatically (C#) or a powershell script?

Answer

Identify Worker Process in IIS 6.0

Start > Run > Cmd
Go To Windows > System32
Run cscript iisapp.vbs
You will get the list of Running Worker ProcessID and the Application Pool Name.

From IIS 7.0 you need you to run IIS Command Tool ( appcmd ) .

If you want to save that list to text file, just append >> myfile.txt after command.

Now, here you can see iisapp.vbs source code.

It uses WMI to get all the information. Looks simple to rewrite this to C#.

Anyway, complete article where i found this info can be seen here: Identifying Worker Process (w3wp.exe)
