 ## Advanced C# Syntax Highlight

+  The advanced syntax highlight function highlights every aspect of C# language elements with diverse styles, including using various font families and text styles, enlarging or shrinking font sizes, changing foreground or background colors and transparency.

   * Unnecessary code is marked strike-through.

-  * Overriding methods (such as `ToString`) can be painted with gradient background color.
-  * Imported symbols (from external assemblies, e.g. `NotImplementedException`, `ToString`) can be marked with a different style (bold here) from symbols in your code, which are also possible to be styled.

   Syntax definitions under the _All languages_ section apply to all languages; those under _Comment_ section apply to comment taggers (see below), others apply to corresponding languages accordingly.
