In VS2010, is there a way to know which application pool a given w3wp.exe is serving, to then decide to attach the debugger to?

Question

So I'm debugging some websites (one from trunk, one from branch) running locally, in separate apppools. I have trunk and branch solutions open in two VS instances. I'd like to debug trunk in one, and branch in the other. I'd like to know if there's a way to know which application pool each w3wp.exe is serving, to know which one is which when attaching the debugger.

Update: the point of this is to write a macro within VS to then let me have a button (per app-pool that is interesting) which will be clickable to attach the debugger to. So solutions should preferably not involve other programs.

Update2: this is on Windows 7 against IIS7.

Answer 1

If you can execute a request on each branch, you could use something like Process Explorer or Task Manager to see which ID is which possibly as one may be taking up CPU cycles that is currently processing a request assuming you can get such separation.

Answer 2

Look at the answers to this question. There are built in scripts you can run from a command window to do this.
