System.IO.FileNotFoundException - 在发行版中找不到 CefSharp.Core.dll

Question

I've downloaded the CefSharp extension with NuGet reposity and I've tested it with Microsoft Visual Studio.
I've used the default code, it is:

namespace WebBrowser
{
    public partial class WebForm : Form
    {
        public WebForm()
        {
            InitializeComponent();
            InitBrowser();
        }

        public ChromiumWebBrowser browser;
        public void InitBrowser()
        {
            Cef.Initialize(new CefSettings());
            browser = new ChromiumWebBrowser("www.google.com");
            this.Controls.Add(browser);
            browser.Dock = DockStyle.Fill;
        }

        private void WebForm_Load(object sender, EventArgs e)
        {

        }
    }
}

If I run the project in debug, it works well: it open a window with Google. But if I compile the project and I install it with the setup, I get always an error:
System.IO.FileNotFoundException: Could not load file or assembly 'CefSharp.Core.dll' or one of its dependencies.

I've searched on Google, I've tried adding xcopy "$(SolutionDir)packages\\cef.redist.x86.3.2987.1601\\CEF*" "$(TargetDir)" /s /y /i in post compilation and other ways, but nothing works.

What can I try?

Answer 1

Ok, finally I found what is the cause of your problem. CefSharp needs to have some files in root application directory.

In setup project, when selecting files for Application folder, choose Add => File... instead of Add => Project Output... . Then navigate to your build folder and pick all files. This will create 1 to 1 copy of your output files when running setup executable.

I had a similar issue and solved it by installing the following redistributable:
