Comentarios

Cuando se aplica a una clase de implementación de servicio, este atributo indica si este servicio requiere o admite el modo de compatibilidad ASP.NETASP.NET que se va habilitar para el dominio de aplicación del hospedaje (AppDomain).When applied to a service implementation class, this attribute indicates whether this service requires or supports ASP.NETASP.NET compatibility mode to be enabled for the hosting application domain (AppDomain).

Los AppDomains que hospedan servicios WCF se pueden ejecutar en dos modos de hospedaje diferentes:AppDomains hosting WCF services can run in two different hosting modes:

  • Modo de transportes mixtos (valor predeterminado): En este modo, los servicios WCF no participan en la ASP.NETASP.NET canalización http.Mixed Transports Mode (Default): In this mode, WCF services do not participate in the ASP.NETASP.NET HTTP pipeline. Esto garantiza que un servicio WCF se comporte de forma coherente, independientemente del entorno de hospedaje y del transporte.This guarantees that a WCF service behaves consistently, independent of hosting environment and transport.

  • ASP.NETASP.NETModo de compatibilidad: En este modo, los servicios WCF participan en ASP.NETASP.NET la canalización http de manera similar a los servicios ASMX.Compatibility Mode: In this mode, WCF services participate in the ASP.NETASP.NET HTTP pipeline in a manner similar to ASMX services. ASP.NETASP.NETcaracterísticas como autorización de archivo, autorización URL y estado de sesión HTTP son aplicables a los servicios WCF que se ejecutan en este modo.features such as File Authorization, UrlAuthorization, and HTTP Session State are applicable to WCF services running in this mode.

La marca de configuración en el nivel de la aplicación aspNetCompatibilityEnabled controla el modo de hospedaje.The hosting mode is controlled by the application-level configuration flag aspNetCompatibilityEnabled.

<system.serviceModel>

<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>

</system.serviceModel>

Esta marca es false de forma predeterminada y, por tanto, los servicios WCF se ejecutan en el modo de transportes mixtos, a menos que se opte explícitamente por el modo de ASP.NETASP.NET compatibilidad.This flag is false by default and thus WCF services run in the Mixed Transports Mode unless you explicitly opt into the ASP.NETASP.NET compatibility mode.

Para obtener más información sobre el modo de compatibilidad de ASP.net, vea <serviceHostingEnvironment>.For more information about ASP.NET compatibility mode, see <serviceHostingEnvironment>.

Utilice la propiedad RequirementsMode para hacerlo.Use the RequirementsMode property to do this. En el tiempo de ejecución, las aplicaciones pueden detectar si el modo de compatibilidad ASP.NETASP.NET está habilitado comprobando el valor de la propiedad AspNetCompatibilityEnabled estática.At runtime, applications can detect if ASP.NETASP.NET compatibility mode is enabled by checking the value of the static property AspNetCompatibilityEnabled.
