You might think, "why do I care about this if I just do IIS 7". The reason is that IIS 7 allows you to create applications using these technologies (aside from Avalon) and you WILL see IIS 7 applications that make heavy use of Workflow to track processes in applications as well as even determine which page to show in a web application. Imagine having an IIS 7 module that determined which pages to show based on a users membership level, region, lanugage, rights on the site, etc. CardSpace is a part of this too - and I keep saying this so get used to it - CARDSPACE IS HUGE. HUGE. In two-three years that is all you're gonna hear about. Finally Windows Communication Foundation - for web services has a big tie in to IIS 7 as it can host WCF services.

IIS 7 lets you take advantage of these technologies and offer them as modules or handlers to all your sites. Or extend them in an application to use in tracing and troublehsooting logs.

So, free training for developers intersted in this stuff. This will not be free after Vista ships.

After you've looked at this, look at IIS.net on how to write a managed module or handler and let me know if you have a cool idea about how to integrated IIS7 and .NET 3.0
