Upcoming Microsoft Visual Studio 2010, Rosario

While reading to some article yesterday ...
I came across the new version of the Visual Studio of Microsoft, the Visual Studio Team System (VSTS) 2010, code-named Rosario.

The VSTS 2010 is expected to be equipped with .Net framework 4.0, and jQuery.

Microsoft plans to focus on five areas: riding the next-generation platform wave, inspiring developer delight, powering breakthrough departmental applications, enabling emerging trends such as cloud computing, and the Application Lifecycle Management (ALM).

Additionally, Microsoft also announced that VSTS 2010 will provide a unified VSTS Development and Database product. Any customer with Visual Studio Team System 2008 Development Edition or Visual Studio Team System 2008 Database Edition and a service contract will be able to get a free upgrade to Visual Studio Team System 2008 Development Edition or Database Edition.
