Today we are excited to announce the release of the Windows Azure AppFabric
June CTP which includes capabilities that make it easy for developers to
build, deploy, manage and monitor multi-tier applications across web, business
logic and database tiers as a single logical entity on the Windows Azure
Platform.

This CTP release consists:

• AppFabric Developer Tools – Enhancements to Visual Studio that enable
  to visually design and build end-to-end applications on the Windows Azure
  platform.
• AppFabric Application Manager – Powerful, yet easy way to host and
  manage n-tier applications that span web, middle and data-tier through the
  entire application lifecycle including deployment, configuration, monitoring and
  troubleshooting. The Application Manager includes a comprehensive application
  management portal that is powered by a REST API for monitoring the health of
  your n-tier application and performing management operations on the running
  applications.
• Composition Model – A set of .NET Framework extensions for composing
  applications on the Windows Azure platform. This builds on the familiar Azure
  Service Model concepts and adds new capabilities for describing and integrating
  the components of an application. The AppFabric Developer Tools leverage the
  composition model to create an application manifest that is used by the
  AppFabric Application Manager at deployment time to understand the application
  structure and metadata.
• Support for running Custom Code, WCF, WF – Formal support for
  executing Windows Workflow Foundation (WF) on Windows Azure and the composition
  of Windows Communication Foundation (WCF) and WF services, as well as custom
  code, into a composite application. In addition, it provides enhanced
  development, deployment, management and monitoring support for WCF and WF
  services.
