Early next year we'll ship the final release of IIS 7.0 as part of the Windows Server 2008 release.  As I've blogged about in the past, IIS 7.0 is a major update of our web-server stack, and introduces a significantly new and improved extensibility, configuration and administration architecture. 

One of the really cool things about IIS 7.0 is that it is all nicely integrated with the .NET Framework, and enables you to use any .NET language to extend and customize the server.  You can now easily do things in VB and C# that previously required writing a pretty gnarly C++ ISAPI.  The deployment, management and administration of web applications on the server is also now nicely unified across IIS and ASP.NET.

We will also shortly begin sharing details of a new web application deployment framework for IIS that enables you to easily automate the deployment of web applications on either a single server or across a web farm of machines.  It will make it easy to version your web applications (including allowing you to quickly roll back to previous versions), as well as automatically provision them across multiple servers.  It also enables the full automation of deployment tasks (including via both command-line and PowerShell scripting APIs).  The combination of IIS7 with this web deployment framework will enable you to deploy and scale your ASP.NET server applications better than ever before.
