CefSharp-无法加载文件或程序集“ CefSharp.Core.dll”或其依赖项之一 [英] CefSharp - Could not load file or assembly 'CefSharp.Core.dll' or one of its dependencies

问题描述

我使用CefSharp WinForms应用程序已经有几周了，但没有任何问题。今天早上，在向应用程序添加一些内容的同时，我尝试运行它以测试某些内容并得到以下错误：

I've been working on a CefSharp WinForms app for a few weeks and I've had no issues with it. This morning, while adding a few things to the application, I tried to run it to test something and got the below error:

系统。 IO.FileNotFoundException未处理消息：
mscorlib.dll中发生了类型为'System.IO.FileNotFoundException'的未处理
异常。其他信息：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
。

System.IO.FileNotFoundException was unhandled Message: An unhandled exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll Additional information: Could not load file or assembly 'CefSharp.Core.dll' or one of its dependencies. The specified module could not be found.

搜索了一会后，我发现：

After searching for a while I found this:

https://github.com/ cefsharp / CefSharp / wiki / Frequently-asked-questions＃Runtime_dependencies

我检查了bin / Debug / x86项目，所有依赖项似乎都是当下。更重要的是，它在五分钟前运行良好，对于Entity Framework迁移，我只接触了一个类。

I checked bin/Debug/x86 for the project and all of the dependencies appear to be present. More importantly, it had been working fine five minutes earlier, and I didn't touch anything beyond a single class for an Entity Framework migration.

重建解决方案，重新启动Visual Studio，重新启动PC并清除/ bin / Debug，但这些都无济于事。

I've tried cleaning and rebuilding the solution, restarting Visual Studio, restarting my PC, and clearing out /bin/Debug, and none of these have helped.

为什么多次出现此错误现在会出现天没有它，如何解决这个问题？

Why would this error appear now after several days without it, and how can I resolve the issue?

编辑：我已经做了一些进一步的实验，我能够该应用程序以发布模式运行，而不是在调试模式下运行。如果我将发布模式的输出路径更改为调试，则它会失败并显示相同的错误（同样，它会在调试中使用发布输出路径成功）。

I've done some further experimenting and I'm able to get the application to run in Release mode but not Debug mode. If I change the output path of Release mode to Debug, it fails with the same error (likewise, it succeeds in Debug with the Release output path).

推荐答案

首先，确保安装了VC ++发行版：

First, make sure you installed the the VC++ distribution:

Cefsharp v65及更高版本，下载VC ++ 2015 Redist，较旧的CefSharp版本使用VC ++ 2013 Redist。

Cefsharp v65 and above, download VC++ 2015 Redist, older CefSharp versions use VC ++ 2013 Redist.

第二，我之前没有看到有人提到过，在处理了几个小时后，我找到了这个解决方案：

Second, which I didn't see people mentioned this before, and i found this solution after I was working with the issue for several hours:

某些CefSharp版本需要CRT包。请在 C：\Program Files（x86）\Windows Kits\10\Redist\ucrt\DLLs 中找到它们，选择正确的版本文件夹（x86或x64，取决于您的CefSharp目标），将所有文件复制到项目的发布文件夹中。

Some CefSharp version needs CRT pack. Please find them at "C:\Program Files (x86)\Windows Kits\10\Redist\ucrt\DLLs", choose the proper version folder (x86 or x64, depends on your CefSharp target), copy all files into the release folder of your project.
