Is it possible to attached an ANTS Performance Profiler to an already running IISExpress process?

I'm trying to figure out how to attach an ANTS profiler to an already running IISExpress instance.

When I try to manually do that, it keeps saying that the port is already in use, which of course is obvious. But why is ANTS trying to start up a new instance when I just said attach?

Why do I want to do this? Because my start up is slow and yes, I know one can just highlight the area in the timeline that I care about, but I'm curious if this is possible none-the-less.

You should be able to connect to IIS Express the same as any other process. Redgate's has a guide to setting it up here.

All you should need to do is click the tab on the left that says "Attach to .NET 4 process", and pick out iisexpress.exe from the list.

It's not possible to add instrumentation to a process that's already been started, so you lose a lot of precision this way, as well as the ability to tie profiling data to individual requests.
