Syntax Highlighting in Visual Studio
Keywords, including ones that have a contextual characteristic, are highlighted in the Visual Studio code editor. Assuming a default color scheme, sequences of characters that have a special meaning in a given context are blue.
For Figure 4.4, I’ve changed the default setting to make keywords appear bold. Settings to control the code editor’s look and feel can be found under Tools, Options, Environment, Fonts and Colors. Select Keyword under Display items to control this setting for (contextual) keywords. Notice how the background compiler for C# recognizes the contextual use of the
value keyword, asking the code editor to format it appropriately only in that particular context.
