The Windows Server 2008 operating system brings a powerful
set of features to the .NET Framework developer. The .NET Framework version 2.0
is included in all the versions of Windows Server 2008. Internet Information
Services (IIS) 7.0 includes new flexibility and capabilities for building
scalable Web sites and applications. By adding the Application Server role,
Windows Server 2008 enables an improved environment for deploying and running
custom, server-based business applications. It also includes support for Web
services built on Windows Communication Foundation (WCF), Windows Workflow
Foundation (WF), and more.
If you have existing .NET Framework applications, you should
be aware of the available support provided by Windows Server 2008 for the various
.NET Framework versions. The following table outlines the support provided.
