Microsoft published more information today about Visual Studio 10 and .NET 4.0. Click here to read the Press Pass and here to read some additional information.

Oh, and for SA customers, some really interesting news has come out that will impact you in just a few days:

Microsoft also announced that VSTS 2010 will provide a unified VSTS Development and Database product. As a benefit to existing Software Assurance (SA) customers, those who currently own Visual Studio Team System 2008 Development Edition or Visual Studio Team System 2008 Database Edition will receive all the following products starting Oct. 1, 2008, for free:

• Visual Studio Team System 2008 Development Edition

• Visual Studio Team System 2008 Database Edition

• Visual Studio 2005 Team System for Software Developers

• Visual Studio 2005 Team System for Database Professionals

Last week, Microsoft announced that they had joined the Object Management Group. OMG is the consortium responsible for many distributed, and object-oriented specifications. One of their sets of standards defines the Unified Modeling Language (UML), and I'm sure that's the reason Microsoft joined the ranks.

Knowing what's coming in the Rosario (and beyond) versions of Visual Studio Team System, I'm glad to see this happening, as it reinforces that Microsoft is taking their modeling strategy to the mainstream.

Now that Team Foundation Server 2008 is out, the Visual Studio Team System product team is totally focused on the next version, known as Rosario. If the current release rhythm continues, Rosario is likely to be released in 2010 (Visual Studio 2005 was released in November 2005, and Visual Studio 2008 was released in November 2007).

The latest version of Rosario is now available for public download on the Microsoft download site. This version is called the April Community Technology Preview (CTP). It's called a CTP because the product is still under development. The CTP gives the development community an opportunity to see what's been produced so far and provide feedback. It's not called a Beta because the bits have not been as thoroughly tested. For this reason, Microsoft recommends that this CTP release not be used for any sort of production development.

The product team has made impressive progress so far. Rich Hundhausen and I got a sneak preview of this CTP a few weeks ago, and what I saw blew my socks off! Whereas the new features in Team Foundation Server 2008 focused mainly on improvements to build and version control, the main areas of focus for Rosario are project management, design and test (Although I'm interested in all things Team System, I'm somewhat partial to project management).

This April CTP is the third CTP release for Rosario. To see the features included in each release, as well as a slick way to download the beast, check out these posts from Jeff Beehler:

• August 2007 CTP
• November 2007 CTP
• April 2008 CTP (download this one!)

Not only did Microsoft just recently post Beta 2 of Visual Studio 2008 (Orcas) a few days ago, but yesterday Microsoft made a CTP of the next generation of Visual Studio Team System (codename Rosario) available for download. Craziness ... which do I spend my time with? It's like having two mistresses to pick from.

Anyway, here are the details, if you want to start playing with Rosario: (keep in mind that it won't ship until some time [6,12,18?] months post Visual Studio 2008, so at least 2009):

• Read Jeff Beehler's blog posting
• Read the Rosario Overview whitepaper
• Download the VPC images (8+ files, 700mb each)
• Download the Rosario documentation
