Microsoft is postponing the planned 22 March, 2010 launch date of Visual Studio 2010 by a few weeks, because of performance issues, according to a Microsoft executive.
The delay, slipped out in a blog post, was due to performance issues identified by beta testers, said S. Somasegar, senior vice president of the Microsoft developer division.
"You have ... given us feedback around performance issues, specifically in a few key scenarios including virtual memory usage. As you may have seen, we significantly improved performance between beta 1 and beta 2. Based on what we've heard, we clearly needed to do more work. Over the last couple of months, our engineering team has been doing a push to improve performance."
Visual Studio 2010 beta 2 and the accompanying .Net Framework 4 programming platform shipped in October.
The extended beta period will include an additional interim checkpoint release, a release candidate that will be publicly available around the February 2010, Somasegar said.
"The [Visual Studio] team will need some time to react to that feedback before creating the final release build. We are therefore moving the launch of Visual Studio 2010 and .Net Framework 4 back a few weeks," he said.
Visual Studio 2010 is set to serve as a lynchpin for developing Microsoft SharePoint-based collaborative applications. It also has boasted a slimmed-down SDK and interoperability between Visual Basic, C#, and dynamic languages. Other capabilities include historical debugging, Silverlight rich Internet application development and Windows Presentation Foundation capabilities for the IDE.
The 2010 version of Visual Studio also is positioned as a platform to use for developing for Windows 7 and the Windows Azure cloud platform. It also supports software processes with Microsoft's Team Foundation Server application lifecycle management server. Multi-monitor support also has been touted for Visual Studio 2010. .Net Framework 4 was to feature SharePoint capabilities and a reduction in size.
