I tried this on my .net 4.0 site with integrated managed pipeline. As soon as I tried to browse the site, w3wp process jump to use 100% CPU and site can't load. Removing the module entry in web.confg can bring back the site to normal.
All I did in set up, were copying the dll to /bin folder, adding the module entry in web.config.
we use win2008 R2, IIS 7.5.
Thanks in advance for any help!
