Disabling of Visual Theme in Compatibility Settings (shortcut for devenv.exe) turns to inability to open or "save as" any files and projects in Visual Studio Environment. Visual Studio responses with "classfactory cannot supply requested class" and that's all. Removing of this setting restores the normal behaviour - I can open and save the files

I tried to disable this setting for other applications and didn't see any problems. Everything works perfectly.

I've fixed this issue in our latest internal build. It's not yet certain whether or not the fix will be available in the service pack or in VS 11.0, but you should see the fix in a future release.

In case this information is useful for future consideration: You asked why someone would run VS2008 under compatibility settings. In my case, I selected "Disable visual themes" to prevent significant flicker in the Solution Explorer when navigating through an ASP/ASP.NET file. I am using Win7 x64.

Hi UltimateQuestion,

Thanks for your feedback, unfortunately at this point the Visual Studio 2010 release is locked down, and this bug does not meet the bar for a 2008 servicing patch. We will review this issue again for sp1, in the mean time we apologies for any inconvenience caused, and thank you for bringing this issue to our attention.

yes, the same problem appears in Visual Studio 2010 RC1. When I disable "Visual themes", a "Open File" dialog doesn't work anymore. I'm getting the same error "classfactory cannot supply requested class"

Should I report the bug for 2010 or it's enought here?

Hi UltimateQuestion,

Thanks for your feedback in this area, have you tried your scenario in the RC release of Visual Studio 2010? Does the same issue occur?

Because VS 2008 is slow. Disabling of Themes makes it a bit faster, especially in Windows 7.

P.s.: I know, there is VS2010 on the road, but not everybody updates immediately
