You can personalize Visual Studio in various ways to best support your development style and requirements. Many of your settings can also be shared with another developer or you can also use the same settings on another device.
But there are also few customizations which developer can make to increase their productivity and write code with ease on that particular Visual Studio instance or particular machine, such as, Full-Screen Mode, Split window, etc.
In Virtual Space mode, spaces are inserted at the end of each line of code. You can choose this option to position comments at a consistent point next to your code.
You can enable/disable this option from Tools > Options > Text Editor > All Languages > General, and under Settings, select Enable Virtual Space.
An instance of an editor window can be split into two separate views for easier editing. Click within the editor window to give it focus.
Select the Window > Split menu option and you will see the editing area divides into two panes separated by a splitter bar.
You can change the default Font and Size, and change the foreground and background colors for various text Display items in the code editor.
You can change the settings from the Tools > Options > Environment > Fonts and Colors.
Let's change the size to 12 and also change the color of the Comment display item and make it bold as shown below.
