dotnet10-csharp14

Apply C# 14 features like the `field` keyword for inline property validation and `nameof(List<>)` for generic metadata to refactor DTOs and domain invariants. This approach improves expressiveness and safety without introducing unnecessary codebase churn.

The best way to adopt .NET 10 and C# 14 without churn is to follow strict adoption rules that only apply new features when they measurably improve expressiveness, safety, or performance. Map each feature to concrete use cases like service assignment patterns and optional partial member structuring.

Use null-safe assignment in C# 14 backend service layers when you need safer value assignments without adding explicit null-check boilerplate. The `?.=` operator improves null safety and performance across API layers while aligning with Clean Architecture conventions.

Yes, you can use the C# 14 `field` keyword for inline property validation to enforce domain invariants. It allows you to validate data directly within property accessors, improving safety and expressiveness without requiring backing field declarations.

Upgrading to C# 14 and .NET 10 does not break Clean Architecture conventions if you enforce compatibility during adoption. The upgrade process connects modern C# constructs to practical scenarios across backend and API layers while strictly following established architectural rules.
