}Para el uso de escaneo async debe llamar a los métodos de destrucción:
YaraSharp . CYaraSharp YSInstance = new CYaraSharp ( ) ;
YaraSharp . CContext YSContext = new YaraSharp . CContext ( ) ;
YaraSharp . CRules YSRules = YSInstance . CompileFromFiles ( RuleFilenames , null , out Errors ) ;
// Async here
YSRules . Destroy ( ) ;
YSContext . Destroy ( ) ; Documentación de la API de Libyara C para una descripción general sobre cómo usar Libyara.
