Visual Studio Breakpoint Bar Not Present (Glyph margin, Overview Ruler)
Tools -> Options -> Text Editor -> Indication Marker (For border breakpoints)
Tools -> Options -> Text Editor -> All Languages -> Line Numbers (For line numbers)
- Go to Tools → Options → Text Editor → General
- Check Indicator Margin
