我正在编写我的第一个 Windows Phone 教程。我已经下载了 sdk 和更新。我正在按照下面的教程进行操作。
当我编译并单击调试时，模拟器启动并且 UI 正确显示。问题是当我点击“开始”按钮时，什么也没有发生。该应用程序应显示上面文本框中的 url。
有谁知道为什么，对不起，如果很明显，但我今天已经开始从android背景学习这个。
Partial Public Class MainPage
Inherits PhoneApplicationPage
' Constructor
Public Sub New()
InitializeComponent()
End Sub
Private Sub url_TextChanged(sender As System.Object, e As System.Windows.Controls.TextChangedEventArgs) Handles url.TextChanged
End Sub
Private Sub Go_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
Dim site As String
site = URL.Text
MiniBrowser.Navigate(New Uri(site, UriKind.Absolute))
End Sub
End Class
