A few months ago I imported the HTML5/CSS3 update into Visual Web Developer 2010, and after the update ended I could not open CSS files in the Visual Studio editor. When I try I get the error:
The operation could not be completed. Unspecified error
Here is a image of the error:
I have opened the file successfully in Notepad++, but can be a hassle to do that every time I need to edit CSS or want to debug and switch windows. Why is this happening? What can I do about it? Is my CSS editor broken for good?
