Microsoft also highlighted its new .NET 4.5 Developer Preview, which has focused on key developer requests across key technologies and includes new features for asynchronous programming in C# and Visual Basic, support for state machines in Windows Workflow, and increased investments in HTML5 and CSS3 in ASP.NET.

In addition, Scott Guthrie, corporate vice president in Microsoft's STB unit, demonstrated the new ASP.NET MVC 4 Preview, which provides new Web tooling capabilities for developers to better manage Web application rendering, and its impacts on business application logic, in different browsers.

Microsoft also showcased additional capabilities of the Windows Azure platform, such as the new Windows Azure Toolkit for Windows 8, which is currently available for Windows Phone, Android and iOS. Zander said Microsoft is extending its toolkits for cloud applications to Windows 8. The Windows Azure Toolkit for Windows 8 provides developers with code samples, documentation and components for building Metro-style applications that use Windows Azure for connectivity and notifications.

Other new Windows Azure updates from BUILD include the following:

- Windows Azure Georeplication. Now available, this enhancement replicates Windows Azure Blobs and Tables between two data centers hundreds of miles apart from each other on the same continent, at no additional cost, to provide additional data durability in the case of a major disaster.

- Windows Azure Marketplace expansion. Available in 25 new countries in early October, the Windows Azure Marketplace offers developers a comprehensive market for datasets and finished applications; you can register on Windows Azure Marketplace.

- Microsoft Translator API. Available now on the Windows Azure Marketplace, the Microsoft Translator API provides machine language translations to developers looking to customize their applications to satisfy the language needs of a global audience.

- Windows Azure SDK version 1.5. Advancements to the Windows Azure SDK include better capabilities for developers to build Windows Azure applications, including improved emulator performance, service certificate support, package and configuration management, and remote desktop encryption.

- Windows Azure Service Bus September Release. Enhancements to the Service Bus improve pub/sub messaging, enable asynchronous eventing to better link applications to occasionally connected devices such as phones and kiosks, and provide improved support for loosely coupled application architectures and advanced intra-app messaging.
