Architectural Overview
AppFabric requires .NET Framework 4 as a foundation. It also requires the Windows Process Activation service (WAS) and IIS Manager. To support management and deployment of WCF and WF services, AppFabric provides management APIs and tools that you can use either from the IIS Management console or from Windows PowerShell. AppFabric also provides several run-time services and stores for the monitoring and persistence of hosted services and workflows.
The topics in this section provide more detail about AppFabric architecture.
