More than a year after the release of Visual Studio 2005, Microsoft has finished VS 2005 SP 1. The service pack addresses issues Microsoft discovered through both internal testing and customer feedback.
In all, there are more than 70 enhancements, ranging from support for mobile devices and the SQL Sever Compact Edition to integration with Excel 2007 and Project 2007. In addition, the service pack includes the Web Application Project, which is a previously released tool for migrating Web apps from ASP.NET 1.x to ASP.NET 2.0.
Three service packs are available now:
- Visual Studio 2005 Team Suite SP1 -- This edition covers the standard, professional and team versions of Visual Studio 2005.
- Visual Studio 2005 Team Foundation Server SP1
- Visual Studio 2005 Express Editions SP1 -- Separate downloads are available for the five free versions of Visual Studio 2005: Visual Basic, Visual C++, Visual C#, J# and Web Dev.
Finally, there is a Visual Studio 2005 SP1 Update for Windows Vista Beta. This service pack, aimed at developers using VS 2005 in conjunction with Vista, will officially ship after the new operating system ships in early 2007.
More information about all the releases is available at the Visual Studio 2005 Service Pack 1 development center.
