GeckoFX要求XULAppInfo

Question

安装了带有最新稳定版本(45.0.30)的GeckoFx，试图初始化它第一次请求XULAppInfo的火狐，然后给出了一个错误说明：

System.NotImplementedException‘发生在Geckofx-Core.dll中，但未在用户代码中处理 附加信息:方法或操作未实现。

有关守则：

public Form1() {
    Xpcom.Initialize("FireFox");
    InitializeComponent();
}

堆栈跟踪是：

Answer 1

我正在使用vb.net，也有同样的问题，但我修复了它。我只是写了以下几行：

Xpcom.EnableProfileMonitoring = False

然后：

Xpcom.Initialize("Firefox")

完整的例子：

Dim ss As New GeckoWebBrowser

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Xpcom.EnableProfileMonitoring = False
        Xpcom.Initialize("Firefox")
        ss.Dock = DockStyle.Fill
        Me.Controls.Add(ss)
        ss.Navigate("www.google.com")
 End Sub
