GraphQL.NET es un framework del lado del servidor para construir y ejecutar APIs de GraphQL dentro de aplicaciones C#. Proporciona un toolkit integral para la construcción de esquemas, un motor federado para grafos de datos distribuidos y un manejador de suscripciones para gestionar flujos de datos en tiempo real. El proyecto se distingue por un constructor de esquemas flexible que admite tanto definiciones programáticas code-first como enfoques declarativos schema-first utilizando el lenguaje de definición de esquemas estándar. Incluye un motor de federación dedicado para dividir grafos de datos en subgrafos y componerlos en una puerta de enlace unificada, así como una implementación de cargador de datos (data loader) diseñada específicamente para resolver el problema de consultas N+1 mediante procesamiento por lotes y caché. El framework cubre una amplia gama de capacidades operativas, incluyendo la integración de inyección de dependencias para la gestión del ciclo de vida de los servicios, pipelines de middleware para la interceptación de resolución de campos y un pipeline de ejecución optimizado con tipos de valor para reducir las asignaciones de memoria.
