We've had a couple of queries about the ASP.NET management pack guide. It's in the process of being released, but in the meantime, use the copy attached to this post. [Edit: If you don't see the attachment at the bottom of the post, come to our blog page and click the green post title. It will take you to a page with the attachment at the bottom.]
If you're reading this post after June 2008, check the management pack for the latest guide; it's possible the guide will have changed since I posted this.
