prettier-plugin-csharp

library0.6.0-developmentjsnpmunverified

A Prettier plugin to format C# code using Prettier's opinionated style. Current version is 0.6.0-development, indicating pre-release status with active development. Released under a permissive license. Differentiator: brings Prettier's zero-config, deterministic formatting to C# projects, unlike other C# formatters that require extensive configuration. However, due to its early stage, it may break code and is not ready for production use.
