Cómo definir manualmente un modelo Entity Data Model (Entity Framework)

  • Artículo

En este tema se muestra cómo crear manualmente los archivos de asignaciones que definen el modelo Entity Data Model (EDM) AdventureWorks Sales. El modelo AdventureWorks Sales es un subconjunto del modelo AdventureWorks completo que se utiliza en los temas relacionados con tareas en la documentación de Entity Framework. Si genera manualmente los archivos de asignaciones, seguirá teniendo que configurar el proyecto de Visual Studio para usar Entity Framework. Para obtener más información, vea Cómo configurar manualmente un proyecto de Entity Framework.

Nota

Si usa el Asistente para Entity Data Model en un proyecto de Visual Studio, genera automáticamente un modelo Entity Data Model (EDM) y configura el proyecto para usar Entity Framework. Para obtener más información, vea Cómo usar el Asistente para Entity Data Model (Entity Framework).
