I open a single html file (not from a project) with VS2013 and I'm not able to switch to design view.
- Windows Explorer -> Right click on html file -> Open with - Visual Studio 2013
It's the same if I start VS 2013 -> File -> Open -> File -> choose single html file
Got a workaround right now:
Start VS2013 -> File -> Open -> Web Site-> Select folder which contains the single html file I'd like to change.
In Solution Explorer now appears the folder with the containing file -> right click on the single html file -> Open with.. -> Html (Web Forms) Editor.
Anyway. It would be nice, if I could use VS 2013 as single file html editor like it was with VS2012.
