 Code-style language rules affect how various constructs of .NET programming languages, for example, modifiers, and parentheses, are used. The rules fall into the following categories:
 
-- [.NET style rules](#net-style-rules): Rules that apply to both C# and Visual Basic. The EditorConfig option names for these rules start with `dotnet_style_` prefix.
-- [C# style rules](#c-style-rules): Rules that are specific to C# language only. The EditorConfig option names for these rules start with `csharp_style_` prefix.
-- [Visual Basic style rules](#visual-basic-style-rules): Rules that are specific to Visual Basic language only. The EditorConfig option names for these rules start with `visual_basic_style_` prefix.
+- [.NET style rules](#net-style-rules): Rules that apply to both C# and Visual Basic. The option names for these rules start with the prefix `dotnet_style_`.

+- [Visual Basic style rules](#visual-basic-style-rules): Rules that are specific to Visual Basic code. The option names for these rules start with the prefix `visual_basic_style_`.
 
 ## Option format
 
 Options for language rules can be specified in a [configuration file](../configuration-files.md) with the following format:
 
-`option_name = value` (Visual Studio 2019 version 16.9 Preview 2 and later)
