Modernizing C# code requires analyzing your repository's LangVersion and TargetFramework settings to determine safe feature adoption. This process yields a concrete delta plan containing code changes, documentation updates, and validation steps that respect your SDK constraints.

When upgrading to C# 13 or 14, safe language features depend on your explicit LangVersion and TargetFramework settings. Evaluating these constraints helps produce a concrete delta plan that ensures version-aware usage and compatibility within your specific .NET repository environment.

Planning a safe C# version upgrade involves identifying version-aware language usage and producing a concrete delta plan. This plan includes specific code changes, documentation, tests, and CI notes designed to keep your .NET repository within its target framework and SDK constraints.

Yes, upgrading LangVersion can affect compatibility if new language features require newer runtime capabilities not present in your TargetFramework. Analyzing both settings ensures you only adopt modern C# features that remain safely compatible with your current SDK constraints.

The primary limitation when refactoring to use modern C# features is the repository's explicit TargetFramework and SDK constraints. You must ensure that any version-aware language usage stays within these boundaries to avoid introducing runtime incompatibilities or build failures.
