WCF in an ASP.Net app uses same threadpool as ASP.Net app?

[Keltic]

I have an ASP.Net app with multiple pages.I have added a WCF to this ASP.Net app.If I call this WCF from some pages in parent ASP.Net app, will WCF use the same thread pool as the parent ASP.Net app, or each will have their own dedicated thread pools? I know if WCF is not in the ASP.Net app then it will use a separate thread pool.
