Esta semana la cosecha ha sido especialmente prolífica y traemos más de 70 enlaces a contenidos que creo que vale la pena echar un vistazo, como siempre, categorizados por área de interés: .NET, ASP.NET Core, Azure, patrones y buenas prácticas, acceso a datos, inteligencia artificial, programación web (HTML, CSS, Javascript...), herramientas de desarrollo, .NET MAUI y otros.
Como vengo haciendo últimamente, me gustaría destacar el gran post de José Manuel Alarcón sobre técnicas de carga especulativa en páginas web que te ayudarán a mejorar el rendimiento de las aplicaciones.
Muy bueno también el deep dive de Ricardo Peres sobre los tokens de cancelación de tareas, a veces unos grandes desconocidos.
Por último, dos avisos a navegantes: primero, David Grace nos recuerda que en .NET 9, los proyectos de APIs ya no incorporan por defecto Swagger y propone algunas alternativas, y, segundo, Steve Smith alerta de los peligros de usar eventos de .NET en aplicaciones ASP.NET Core y aporta opciones para conseguir lo mismo.
Todo esto, y mucho más, a continuación...
