WPF application using CEFSharp Web Browser crashing in clickonce release

ClickOnce by default doesn't include the unamanged resources that CefSharp requires. There are many issues that already address this topic.

Here are a couple of useful ones

• https://github.com/cefsharp/CefSharp/issues/1314
• Deploying WPF Application with 3rd Party DLLs

Searching the GitHub project is always an excellent resource. https://github.com/cefsharp/CefSharp/search?q=clickonce&type=Issues&utf8=%E2%9C%93

You also need to make sure VC++ Redist is installed on your target machines. See https://github.com/cefsharp/CefSharp#version-branches for more info one which VC++ version you require.

In general, please try searching GitHub/StackOverflow before posting your question.
