C# 12 / .NET 8 Features

Full support for File-scoped namespaces (namespace MyApp;), Primary Constructors, Collection expressions ([1, 2, 3]), and records.

Security Safeguards

Treats C# code strictly as text data for formatting. NEVER compiles, runs dotnet CLI commands, or executes binaries on the host machine.

Allman & K&R Styles

Support for Microsoft Allman (New Line \n{) and K&R (Same Line {) brace styles, nullable reference types (string?), and required properties.

Raw Strings & XML Doc

Raw string literals ("""raw"""), attributes ([ApiController]), and XML documentation comments (///) are preserved verbatim.
