Nullable and AOT

Nullable annotations

Every public API is annotated. Null-check helpers tell the compiler about the result:

string? input = GetInput();

if (input.IsNotNullOrEmpty())
    Console.WriteLine(input.Length); // no warning: input is not null here

Trimming and Native AOT

The package is marked IsAotCompatible. CI publishes a test app with Native AOT on every pull request and fails on any trimming warning.

A few reflection-based helpers cannot be fully trimmed. They carry [RequiresUnreferencedCode] or [RequiresDynamicCode], so you get a warning at the call site:

  • TypesExtensions.GetExtensionMethods, GetExtensionMethod, GetRealType

The Country, Language and Currency model is made of plain objects and interfaces. It does not use reflection.

Conversions, enum helpers and TrySetConvertedValue are AOT-safe since 2.0: they use IParsable<T> and generic enum APIs instead of reflection.
