Modern C# migration is done by detecting the language ceiling from TargetFramework and LangVersion settings, then applying stable feature deltas while validating changes with build and analyzer steps. This ensures feature adoption does not break existing framework constraints.

To determine supported C# features, analyze the project's explicit LangVersion and TargetFramework settings to calculate the real language ceiling. This identifies the stable, repo-supported features available for code quality and performance improvements.

Yes, you can apply C# refactoring without changing the target framework by respecting the existing LangVersion constraints. The process selects stable features compatible with the current framework and validates them through end-to-end build and test analysis.

C# feature migrations often fail the build when selected features exceed the constraints of the TargetFramework or LangVersion settings. Safe migration requires plan-driven changes that prefer repo-supported features and validate with coordinated build and analyzer steps.

Yes, this approach works for .NET projects planning API reshaping and performance improvements by applying version-aware C# features safely. It coordinates with project tooling to validate changes across build, test, and analysis steps.

The primary limitation is the TargetFramework constraint, which caps the available language features regardless of the LangVersion setting. Safe feature selection must respect this ceiling to avoid introducing incompatible code that fails build validation.
