Maybe it\'s trivial but I couldn\'t find an answer to it for several weeks. It\'s set to some light gray color which is very bothersome in a dark color theme.
Any ideas
If you as many of us use ReSharper, highlighting current line can be achieved via:
ReSharper/Options...; Environment/Editor on the left; check "Highlight current Line" on the right.
After that you may need to restart Visual studio and if you do not like the color, change it via:
Tools/Options...; Environment/Fonts and Colors on the left; "ReSharper Current Line Highlight" on the right
