What the Colors for Changed Lines in Visual Studio Mean

If you have change tracking turned on in Visual Studio, then you'll be getting highlights in the right-hand margin of your editor window flagging the condition of lines in the current file. If you're not getting those lines and would like to, then go to Tools | Options | Text Editor and check the Track Changes option.

Here's your quick reference to the colors and icons in the editor window's right-hand margin:

  • Yellow: The line has been changed but not yet saved
  • Green: The line has been changed and saved
  • Orange: The line has been changed, saved, and the change undone
  • Little square dots in the middle of the margin: Break points
  • Little square dot on the right side of the margin: Syntax error
  • Gray block: The portion of the file that's currently being displayed
  • Solid blue line: The current position of the cursor
