This bugged me for a while. It didn’t bug me enough to spend much time looking for it, but every once in a while I would give it a try and then I’d give up again. The problem? When double-clicking a file in the solution explorer, it would open in the windows forms designer. I wanted it to open in code view, but couldn’t find it anywhere in the extensive Visual Studio Options screen. For HTML-view, there was an option, but not for windows forms files. Huh?

That was because I was looking in the wrong place. Right click a .cs file and choose “Open with”. Then select “CSharp editor” and click “Set default”. Duh.
