Visual Studio kodenavn Rosario er versjonen etter Visual Studio Team System 2008. Rosario dreier som om ALM (application lifecycle management) og trekker inn en del nye egenskaper etter Orcas versjonen. Produktteamet har satt sammen en VPC og lagt ut noe dokumentasjon.

Dette vil danne kjernen for Rosario (hentet fra Jeff Beehler's Blog):

• Development scheduling & tracking – by using the hierarchical work item support in Excel, users will now be able to complete work breakdown activities within Excel. For instance, users can import Requirements into Excel and then break down that requirement into Features and from there into associated Tasks. The work item links are automatically created and maintained through Excel so that when these changes are published to the TFS server, the relationships are preserved for everyone to query and report on. In addition, using these relationships, the Work Breakdown spreadsheet can roll up completed and remaining work values from Tasks to their associated features and requirements to show high level status.
• Requirements test coverage and manual testing – test cases are now stored and managed like other work items. As such, a user can run a query to determine which Requirements do not have any test cases associated with them then create new Test Cases at that point. We have greatly enhanced our support for creating manual test cases so that each step can be called out with specific instructions and expected results. When running the manual test, a video recording of the screen can be made in case a bug is found during testing. If a step fails, the tester can file a bug directly from the manual test runner which will prepopulate the bug form with the test steps, a copy of the video recording and a link to the test case making it much easier for testers to create actionable bugs for developers.
• Managing dependencies – using the hierarchical work item support, users can now indicate predecessor and successor relationships between tasks making it much easier to determine what work must come first and what work is blocked behind it. This will enable team members to prioritize their work appropriately and for project managers to use reports to determine bottlenecks within their team.
