Si tiene un servicio CoreWCF basado en NetFraming, se podr\u00edan consumir recursos adicionales del sistema si las conexiones se dejan establecidas en lugar de cerrarlas o cancelarlas. Hay dos escenarios en los que esto puede suceder. Cuando un cliente establece una conexi\u00f3n con el servicio y no env\u00eda datos, el servicio esperar\u00e1 indefinidamente a que el cliente inicie el protocolo de enlace de sesi\u00f3n de NetFraming. Adem\u00e1s, una vez que un cliente ha establecido una sesi\u00f3n, si el cliente no env\u00eda ninguna solicitud durante el per\u00edodo de tiempo configurado en el enlace ReceiverTimeout, la conexi\u00f3n no se cierra correctamente como parte del aborto de la sesi\u00f3n. Los enlaces afectados por este comportamiento son NetTcpBinding, NetNamedPipeBinding y UnixDomainSocketBinding. S\u00f3lo NetTcpBinding tiene la capacidad de aceptar conexiones no locales. Las versiones actualmente compatibles de CoreWCF son v1.4.x y v1.5.x. La soluci\u00f3n se puede encontrar en v1.4.2 y v1.5.3 de los paquetes CoreWCF. Se recomienda a los usuarios que actualicen.
