Windows Azure AppFabric provides common building blocks required by .NET applications when extending their functionality to the cloud, and specifically, the Windows Azure platform. The Windows Azure AppFabric is a key component of the Windows Azure Platform. It includes two services: AppFabric Access Control and AppFabric Service Bus.
This SDK includes API libraries for building connected applications with the Windows Azure AppFabric. It spans the entire spectrum of today’s Internet applications – from rich connected applications with advanced connectivity requirements to Web-style applications that use simple protocols such as HTTP to communicate with the broadest possible range of clients.
As part of the Windows Azure AppFabric September Release, we are now providing both 32- and 64-bit versions of the Windows Azure AppFabric SDK.
In addition to addressing several deployment scenarios for 64-bit computers, Windows Azure AppFabric now enables integration of WCF services that use AppFabric Service Bus endpoints in IIS 7.5, with Windows® Server AppFabric. You can leverage Windows® Server AppFabric functionality to configure and monitor method invocations for the Service Bus endpoints.
The Windows Azure AppFabric SDK September Release is available here for download.
