For those of you who have read my previous blog on My Visual Studio Theme (Dark Visual Studio Theme) or change the theme of Visual Studio 2010 Beta 1 you must have realized that the background doesn’t change to black after restarting Visual Studio. I had earlier reported this bug to Microsoft. Today I got an email (contents below) saying that they have fixed this and can be downloaded using Extension Manager or from Microsoft Visual Studio Gallery website.
You can download the path form ...
Thank you for reporting this bug. We didn't discover it in time to fix it for Beta1, but you should see it fixed for the next release of VS 2010.
For now, there is an extension written by a member of the VS Editor team as a patch that will allow custom background colors to persist. You can find it in VS by going to Tools->Extension Manager and searching for the "BackgroundPatchExtension," or download it from a web browser at this link: http://visualstudiogallery.msdn.microsoft.com/en-us/d53e0db3-6c41-4cf5-8ca1-339aeef1ac30. Once you install it, just make sure it is enabled in the Extension Manager, and your background color should be applied correctly.
Thanks again for trying VS 2010 and sending your feedback!
