Procedura: creare un'estensione di progetto SharePoint

Articolo
02/18/2013

Creare un'estensione di progetto quando si desidera aggiungere la funzionalità a qualsiasi progetto SharePoint aperto in Visual Studio.Per ulteriori informazioni, vedere Estensione del sistema di progetto SharePoint.

Per creare un'estensione di progetto

Creare un progetto Libreria di classi.
Aggiungere riferimenti agli assembly riportati di seguito:
- Microsoft.VisualStudio.SharePoint
- System.ComponentModel.Composition
Creare una classe che consente di implementare l'interfaccia ISharePointProjectExtension.
Aggiungere l'oggetto System.ComponentModel.Composition.ExportAttribute alla classe.Questo attributo consente a Visual Studio di individuare e caricare l'implementazione di ISharePointProjectExtension.Passare il tipo ISharePointProjectExtension al costruttore dell'attributo.
Nell'implementazione del metodo Initialize utilizzare i membri del parametro projectService per definire il comportamento dell'estensione.Questo parametro è un oggetto ISharePointProjectService che fornisce accesso agli eventi definiti nell'interfaccia ISharePointProjectEvents.

Esempio

Nell'esempio di codice seguente viene illustrato come creare un'estensione di progetto semplice che gestisce la maggior parte degli eventi del progetto SharePoint definiti dall'interfaccia ISharePointProjectEvents.Per testare il codice, creare un progetto SharePoint in Visual Studio, quindi aggiungere più progetti alla soluzione, modificare i valori di proprietà del progetto oppure eliminare o escludere un progetto.L'estensione notifica gli eventi mediante la visualizzazione di messaggi nelle finestre Output ed Elenco errori.

In questo esempio viene utilizzato il servizio del progetto SharePoint per scrivere il messaggio nella finestra Output e nella finestra Elenco errori.Per ulteriori informazioni, vedere Utilizzo del servizio di progetto SharePoint.

Per esempi che illustrano come gestire gli eventi ProjectMenuItemsRequested e ProjectPropertiesRequested, vedere Procedura: aggiungere una voce di menu di scelta rapida ai progetti SharePoint e Procedura: aggiungere una proprietà ai progetti SharePoint.

Compilazione del codice

In questo esempio sono richiesti riferimenti agli assembly seguenti:

Microsoft.VisualStudio.SharePoint
System.ComponentModel.Composition

Distribuzione dell'estensione

Per distribuire l'estensione, creare un pacchetto Visual Studio Extension (VSIX) per l'assembly e qualsiasi altro file che si desidera distribuire con l'estensione.Per ulteriori informazioni, vedere Distribuzione di estensioni per gli strumenti di SharePoint in Visual Studio.
