Cefsharp chromium浏览器不仅在Windows Server 2012上首次加载

Question

嗨，我有wpf桌面应用程序。我正在使用cefsharp.wpf铬浏览器打开网页。我从nugetpacakgemanager(版本87.1.132(中添加了cefsharp。它在我的系统(Windows10，64位操作系统(中运行得很好。

但当我在客户端环境(windows 2012 r2，64位操作系统(中运行exe时，奇怪的事情发生了，即浏览器并不是只有在我第一次尝试时才加载的。基本上我有一个按钮&点击按钮，我打开了一个窗口，里面有cefsharp chromium浏览器。所以当窗口第一次打开时，浏览器不会加载任何内容。现在，如果我关闭窗口并再次打开它，浏览器将重定向到我的url。只有第一次浏览器不加载。在第一次之后，它每次都会加载，直到我关闭exe并重试。

如果我关闭exe并再次打开它并尝试打开该窗口，浏览器将不会再次加载任何内容。然后我关闭那个窗口，再试一次，浏览器会完美工作。

我所做的很简单，我在一个窗口中的xaml文件中有浏览器，在加载窗口时的cs文件中，我为浏览器分配一个地址，就这样。

在xaml中<cefSharp:ChromiumWebBrowser x:Name="browser" />

在窗口加载上的xaml.cs中

browser.address = url;//我正在使用www.xero.com登录url(我认为这不重要，因为它第二次确实有效(。

有人能告诉我这里发生了什么事吗？

我有cefsharp的debug.log文件，上面写着：

我验证了locale文件夹，它与本地系统中的文件夹相同。它说拒绝连接，因为它违反了一些东西。。那么当我第二次尝试时，它就不应该起作用了。所以我完全搞不清楚这里发生了什么。有人能告诉我这里出了什么问题吗？。

救命！

Answer 1

这是非常基本的。我没有初始化Cef。因为第二次没有它也能工作。当应用程序启动时，我确实在App.xaml.cs中初始化了它，现在它每次都能正常工作。尽管我仍然想知道为什么它能工作(如果我第二次加载窗口而没有初始化Cef(。

这是我补充的内容。

if (!Cef.IsInitialized)
{
try
{
//Perform dependency check to make sure all relevant resources are in our output directory.
Cef.Initialize(new CefSettings(), performDependencyCheck: true, browserProcessHandler: null);
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
ErrorLogger.LogError(ex.GetType().ToString(), ex, GetType().FullName, System.Reflection.MethodBase.GetCurrentMethod().Name);
}
}

由于它在我的系统中运行得很好，没有初始化Cef，我认为这不是强制性的。但这似乎是必要的。
