estructuras de datos y WCF habilitado para AJAX llamado desde JavaScript
Publicado por Ella Ilona (3 intervenciones) el 16/12/2012 16:26:08
A continuación se encuentra mi código fuente de un servicio y una página web para aquellos que estén interesados en emplear servicios WCF propios llamados desde script de cliente.
Estaba utilizando VWD 2010 y ASP.NET 4.0; el servicio está configurado con opciones
predeterminadas, como webHttpBinding e enableWebScript (JSON).
El propósito del código es demostrar las correspondencias entre las estructuras "DataContract" y los objetos en JavaScript, con tal que se utilice el control de servidor ScriptManager.
