    Inherits Attribute
'Usage
Dim instance As FeatureConnectorAttribute
[AttributeUsageAttribute(AttributeTargets.Class, AllowMultiple = true)]

Remarks

Apply the FeatureConnectorAttribute to your custom FeatureProvider class to specify a FeatureConnector<TFeatureProviderType> that publishes a service required by your FeatureProvider.

Examples

The following code example shows how to use the FeatureConnectorAttribute to associate a FeatureConnector<TFeatureProviderType> class with a custom feature provider named DiagnosticsMenuProvider. For a complete code listing, see How to: Create a Custom Feature Connector.

' The DiagnosticsMenuProvider class adds a context menu item 
' that displays a dialog box listing the currently running and  
' pending feature connectors. 
<FeatureConnector(GetType(DiagnosticsFeatureConnector))>  _
Public Class DiagnosticsMenuProvider
    Inherits PrimarySelectionContextMenuProvider

    Public Sub New() 
        Dim action As New MenuAction("Feature Diagnostics...")

        AddHandler action.Execute, AddressOf action_Execute 

        Items.Add(action)    
    End Sub 

    Sub action_Execute(ByVal sender As Object, ByVal e As MenuActionEventArgs) 
        Dim service As IDiagnosticsService = e.Context.Services.GetRequiredService(Of IDiagnosticsService)()

        service.ShowWindow()

    End Sub 

End Class
// The DiagnosticsMenuProvider class adds a context menu item 
// that displays a dialog box listing the currently running and  
// pending feature connectors. 
[FeatureConnector(typeof(DiagnosticsFeatureConnector))]
public class DiagnosticsMenuProvider : PrimarySelectionContextMenuProvider 
{
    public DiagnosticsMenuProvider() 
    {
        MenuAction action = new MenuAction("Feature Diagnostics...");

        action.Execute += new EventHandler<MenuActionEventArgs>(action_Execute); 

        Items.Add(action);
    }

    void action_Execute(object sender, MenuActionEventArgs e)
    {
        IDiagnosticsService service = 
            e.Context.Services.GetRequiredService<IDiagnosticsService>();

        service.ShowWindow();
    }
}
