If I hover my cursor on top of a type it will display a tooltip with information about that type, but there is no syntax highlighting.
I set Enable code analysis -> Color identifiers to true in my computer and in both my personal and team-shared solution configuration files. The only things that are colored are comments, primitive types, keywords, and strings.
Have tried to change the colors in Options -> Environment -> Fonts and Colors.
I just installed ReSharper and I'm using the 30-day trial.
I'm using it in an Unreal Engine 4 project solution.
