Esta semana, en la recopilación de enlaces encontramos el interesante repaso de Ricardo Peres a algunas técnicas para optimizar el trabajo con cadenas de texto en .NET en búsquedas, formateo, extracción de subcadenas y uso de interning.

Vale la pena también echar un vistazo a la notación de objetos orientada a tokens (TOON) propuesta por Johann Schopplich para reducir significativamente el coste en tokens al enviar datos estructurados (como JSON) a modelos de lenguaje.

Isaac Ojeda nos muestra cómo utilizar channels y servicios de .NET para crear un sistema de control de tareas en segundo plano, muy interesante.

E imperdible el detallado análisis de Andrew Lock sobre la grave vulnerabilidad "request smuggling" en ASP.NET Core, calificada con una puntuación de 9.9, la más alta hasta la fecha.
