以下是来自Walkthrough: Creating a RIA Services Solution的代码，其中定义了_customerContext。

Imports System.ServiceModel.DomainServices.Client
Imports RIAServicesExample.Web

Partial Public Class MainPage
    Inherits UserControl

    Private _customerContext As New CustomerDomainContext

    Public Sub New()
        InitializeComponent()

        Dim loadOp = Me._customerContext.Load(Me._customerContext.GetCustomersQuery())
        CustomerGrid.ItemsSource = loadOp.Entities
    End Sub

End Class
