- GetOrSetAsync für DateTime mit synchronen und asynchronen Fabrikmethoden implementiert.
- Bestehende GetOrSetAsync-Methoden für Zeichenfolgen und asynchrone Zeichenfolgen refaktoriert, um Klarheit und Struktur zu verbessern.
- Code mit Regionen organisiert, um ähnliche Methoden für bessere Lesbarkeit zu gruppieren.
- TODO für weitere Verbesserungen bei der Codegenerierung für GetOrSetAsync-Methoden hinzugefügt.
