Procedura: definire manualmente i file di modello e di mapping (Entity Framework)

  • Articolo

In questo argomento viene illustrato come creare manualmente i file di modello e di mapping Modello Sales di AdventureWorks. Se i file di modello e di mapping vengono generati manualmente, è comunque necessario configurare il progetto di Visual Studio per l'utilizzo di Entity Framework . Per ulteriori informazioni, vedere Procedura: configurare manualmente un progetto di Entity Framework.

Bb399785.note(it-it,VS.100).gifNota:
Se si utilizza la Procedura guidata Entity Data Model in un progetto Visual Studio, un file .edmx viene automaticamente generato e configurato per l'utilizzo di Entity Framework .Per ulteriori informazioni, vedere Procedura: utilizzare la procedura guidata Entity Data Model (Entity Framework).

Per creare il file SSDL (Store Schema Definition Language)

  • Aggiungere un file denominato AdventureWorks.ssdl alla directory del progetto e incollarvi il contenuto seguente:

Per creare file MSL (Mapping Specification Language)

  • Aggiungere un file denominato AdventureWorks.msl alla directory del progetto e incollarvi il contenuto seguente:
