在我们的某些计算机上,尝试从WPF代码启动CefBrowser时遇到异常.我一直在尝试解决此问题,但无法真正理解出了什么问题.这些机器都是运行64位OS的Win7.

下面,我使用运行“ CefSharp.MinimalExample.Wpf.exe”的“ Dependency Walker”捕获了跟踪. (对于格式,我深表歉意,我不知道该如何改进.)

它开始运行,然后变成标准文本“无法加载文件或程序集’CefSharp.Core.dll’或其依赖项之一.找不到指定的模块.”

所以-有人知道下一步该怎么做吗？我真的猜不到！

解决方法:

CefSharp是使用VC 2012 Update 4构建的.请注意x86和x64的变体,因此请确保您的应用程序匹配它们.
