Since VS2002 the new help system was really bad. And it got even worser in every release of visual studio. The slowest version was starting with VS2005 and VS2008. Now MS has heard us!
April announced on her weblog, that MS has now set up a new team to “redesign” the MSDN Help system:
Help is Getting Help – The Long Overdue Makeover for Visual Studio and MSDN Help
Really great news! Hopefully this project will be successful!
