Languages and Frameworks: C#
JetBrains Rider 2020.2 fully supports all C# versions up to C# 7.0 and partially C# 8.0. C# is the primary programming language JetBrains Rider is intended for, and therefore all JetBrains Rider features (excluding some features specific to other languages) are supported in C# .
By default, JetBrains Rider automatically detects language version based on the associated compiler. However, you can specify the target language version explicitly — press Alt+Enter on the project in the Solution Explorer and use the Language version selector on the Application page of the Project Properties dialog .
Depending on the current language version — whether it is detected automatically or set explicitly — JetBrains Rider adjusts its features. For example, code inspection detects places in your code, which could be simplified using new language features.
Information on JetBrains Rider features in C# is available in the following sections:
