In my error message said
Error 1
>DESCRIPTION : 'okButton_Click' no es un miembro de 'MyOwnWpfWebBrowser.Navigate'.
>FILE :Navigate.g.vb
>LINE :93
>COLUMN :91
>Project :MyOwnWpfWebBrowser
and i do not find the Navigate.g.vb in the obj/Debug directory coyld you explain me how or hwere is it generated?

But i solved the problem at least right now is solved by writing in the Navigate.xaml.vb this code

Partial Public Class Navigate

    Private Sub okButton_Click(ByVal sender As Object, ByVal e As System.Windows.RoutedEventArgs) Handles okButton.Click

    End Sub

End Class

Thank you
