That's situation normal, or at least not uncommon - actual code production frequently outpaces the ability of Microsoft tech writers to publish KB articles.

I have been experiencing an un-ending hang when requesting to open the design view for some form code. I have applied this hotfix but the problem remains.
Project/solution worked in VS2008, originally developed in VS2003, migrated to VS2005 and VS2008 successfully.
Can view the code for all the forms, but even the simplest (smallest) forms will not open, and induce the hang.
Can create NEW form projects ok...old ones will not work.
I notice that the VS2010 process thread in the task manager (devenv.exe*32) is completely maxed out, 100% usage...so it thinks its doing something but likely stuck somewhere.
Using VS2010 Pro 10.0.30319.1

I installed the hotfix, and was behaving well for a few days but now is returning to the form designer crashing. Hopefully take out another hotfix to solve this problem quickly. Please Microsoft
