wpf 加载 CEFSHARP.CORE.DLL 时出现异常

Exception loading CEFSHARP.CORE.DLL

提问by David Sundstr?m Sundstr?m

On someof our machines, we get an exception when trying to start CefBrowser from WPF code. I have been trying to troubleshoot this, but cannot really understand what goes wrong. The machines are all Win7 running 64-bit OS.

在我们的某些机器上，尝试从 WPF 代码启动 CefBrowser 时会出现异常。我一直在尝试解决这个问题，但无法真正理解出了什么问题。这些机器都是运行64位操作系统的Win7。

Below, I have captured a trace using "Dependency Walker" running the "CefSharp.MinimalExample.Wpf.exe". (I apologize for the formatting, I don't know how to improve it.)

下面，我使用运行“CefSharp.MinimalExample.Wpf.exe”的“Dependency Walker”捕获了跟踪。（我为格式道歉，我不知道如何改进它。）

It starts out, then turns into an appcrash with the standard text "Could not load file or assembly 'CefSharp.Core.dll' or one of its dependencies. The specified module could not be found."

它开始，然后变成带有标准文本“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”的appcrash。

So - does anyone know what to do next? I can't really guess!

那么 - 有谁知道下一步该怎么做？我真的猜不透！

For anybody still looking for a solution to this issue, Please the simplest thing to do is to download and install Visual C++ 2012 if you are using CefSharp from Version 55 downwards, and Visual C++ 2013 if you are using CefSharp version 57. Please ensure to install the VC++ build (x86 or x64) depending on your application target chitecture (build). This took me a day and half to realise.

对于仍在寻找此问题解决方案的任何人，如果您使用 CefSharp 55 版以下，请下载并安装 Visual C++ 2012，如果您使用 CefSharp 57 版，请下载并安装 Visual C++ 2013。请确保根据您的应用程序目标架构（构建）安装 VC++ 构建（x86 或 x64）。这花了我一天半的时间才意识到。
