EditorConfig properties for C#: Syntax Style

Last modified: 26 May 2024

This page lists custom JetBrains Rider EditorConfig properties that you can use to configure code syntax style rules. Note that some properties apply to one language while others apply to several languages at once. However, for each multi-language property there is a property that can override it for a specific language, for example, default_private_modifier and csharp_default_private_modifier.

tip

JetBrains Rider also supports most frequently used .NET-coding-convention EditorConfig properties.

tip

Formatting preferences listed on this page can be also configured visually, on the Editor | Code Style | C# | Syntax Style page of JetBrains Rider settings CtrlAlt0S.
