I've created an extension that hides the suggestion margin, but it also hides the outline margin, which might be undesirable for you. The source code is only a few lines as shown in the screenshot, simply removing the outlining line will do the trick.
What happens if you press
Ctrl

at that line? That's the keyboard shortcut for Quick Actions (the light bulb feature). I'm not at my home machine at the moment so I can't test things. – MC10 – 2015-07-29T20:10:39.1431I've played around with it a bit and it doesn't seem like there's any setting or option to turn it off. Quick Actions is a new feature in VS2015. Perhaps you can send Microsoft feedback or a frown and let them know that people don't want this. – MC10 – 2015-07-30T14:09:16.263
