WCF Web Service Client utilizando un CookieContainer

Question

He desarrollado una pequeña aplicación de formulario C# que llama a un servicio web. Todo funciona bien pero necesito mantener el estado y para hacerlo necesito usar un CookieContainer si no me equivoco.

Creé la referencia de servicio utilizando el menú "Agregar referencia de servicio" de mi proyecto y todo funcionó bien. Pero no sé cómo agregar un CookieManager en el cliente creado.

he encontrado algunos ejemplos que mostraban muestras gusta:

serviceClient.CookieContainer=new CookieContainer() 

pero este no es el caso. Mi cliente de servicio no tiene esa propiedad. Por cierto, estoy demandando a Visual Studio 2010 Beta.

¡Gracias de antemano!

Este es el ServiceReference resultado (que se creó automáticamente):

Answer 1

Esta referencia de servicio en creado usando WCF y WCF es independiente del medio real de la comunicación que significa que estos servicios se pueden utilizar ya sea usando servicio web o de interacción remota o MSMQ. Y remoting y MSMQ no tienen un concepto de cookies.

Mejor crea tu referencia de servicio web usando WSDL.exe y agrega la clase resultante en tu proyecto. Yo hice lo mismo.

Answer 2

Citado: Si un método de servicio web XML usa estado de sesión, se pasa una cookie en los encabezados de respuesta al cliente del servicio web XML que identifica de forma exclusiva la sesión para ese cliente de servicio web XML. Para que un servicio web XML mantenga el estado de la sesión para un cliente, el cliente debe almacenar la cookie.

¿Por qué volver a la tecnología anterior, cuando solo puede habilitar las cookies en el enlace?
