The latest episode of the MSDN .NET Show features a great interview with Scott Guthrie and Bill Staples on IIS 7.0. The show includes a 30 minute interview about the product, along with 30 minutes of demos.
IIS 7.0 on the MSDN .NET Show
The latest IIS 7.0 Beta will be included in Windows Vista Beta 2. Also, it will be shipping with Vista, and will be included in the "home" editions as well. I'm hoping the final release of IIS 7 will ship with the RTM of Vista, and I don't have to wait for the Vista Server RTM to use it.
