Visual Studio 2010 SP1

Visual Studio 2010 shipped about 11 months ago, and we continue to work on it and respond to customer feedback received through Visual Studio Connect. This feedback has guided our focus to improve several areas, including IntelliTrace, unit testing, and Silverlight profiling.

You can learn more about how we're improving Visual Studio 2010 on Jason Zander's blog later today. On March 8th, MSDN subscribers will be able to download and install Visual Studio 2010 SP1 from their subscriber downloads. If you're not an MSDN subscriber, you can get the update on Thursday, March 10th.


Сейчас там (на МСДН) СП1 нет.
