Tips and Tricks

Customize Colors for Code Syntax Highlighting

C#, JavaScript, and ASP.NET MVC coding issues can be made more prominent by customizing code syntax colors.

The most common mistake that C# and JavaScript programmers make is missing braces. Another common mistake that ASP.NET MVC Razor programmers make is to not understand what executes on the server and what executes on the client. Both of these problems can be solved using more obvious code syntax highlighting.

The default color scheme is too subtle which makes it too hard to see matching braces and Razor syntax. Figure 1 shows an example -- why is the unit price of our product not being multiplied by 20 percent?

Improve your coding experience with the following steps:

  1. On the Tools menu, choose Options.
  2. In the Environment section, click Fonts and Colors.
  3. In the Display items list, choose Brace Matching (Rectangle) and change the Item background to something bold such as Lime. (See Figure 2.)
  4. Change To Lime

  5. In the Display items list, choose HTML Razor Code Background and change the Item background to something bold such as Yellow. (See Figure 3.)
  6. Change To Yellow

  7. Click OK

Now it's easy to see matching braces and Razor code, as shown in Figure 4.

Now, The Problem Is More Apparent

With the customized coloring of the syntactical elements, it's much quicker to spot why the formula isn't working. Now all you have to do is spot it and then fix it.
