问题
I'm using CefSharp in my C# Windows form Application and it's working well when I run it from visual studio, but when I publish it using FTP account as publish folder and url as installation folder url
but I'm getting the following error,
I followed everything in the manual and copied the needed files into bin folder (CefSharp.BrowserSubprocess.Core.dll, CefSharp.BrowserSubprocess.exe, CefSharp.Core.dll, CefSharp.dll, CefSharp.WinForms.dll, icudtl.dat, libcef.dll)
unfortunately nothing works, where is the problem?
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
回答1:
I managed to collect all the needed files mentioned Here in one folder and name it dll then I put it in the packages folder
now in .csproj and before </Project> I added
<ItemGroup>
<Content Include="$(SolutionDir)packages\dll\**\*.*">
<Link>%(RecursiveDir)%(Filename)%(Extension)</Link>
<Visible>false</Visible>
</Content>
</ItemGroup>
the application wored after the publish and it's solved

I'm a little late but to add on here I use the following as a solution to the problem of moving the CEFSharp files into a subfolder. (Credit to https://gist.github.com/BlackBooth/19ce027c4f68c1eb4fc1144988ca6662)
using CefSharp;
using System;
using System.IO;
using System.Reflection;
using System.Runtime.CompilerServices;
using System.Windows.Forms;
namespace TestApp
{
internal static class Program
{
// The subfolder, where the cefsharp files will be moved to
private static string cefSubFolder = "CEFSharp";
// If the assembly resolver loads cefsharp from another folder, set this to true
private static bool resolved = true;
[STAThread]
private static void Main()
{
AppDomain.CurrentDomain.AssemblyResolve += CurrentDomain_AssemblyResolve;
InitializeCefSharp();
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new MainForm());
}
[MethodImpl(MethodImplOptions.NoInlining)]
private static void InitializeCefSharp()
{
var settings = new CefSettings();
// Set BrowserSubProcessPath when cefsharp moved to the subfolder
if (resolved)
settings.BrowserSubprocessPath = Path.Combine(Application.StartupPath, cefSubFolder, "CefSharp.BrowserSubprocess.exe");
// Make sure you set performDependencyCheck false
Cef.Initialize(settings, shutdownOnProcessExit: true, performDependencyCheck: false);
}
/// <summary>
/// Will attempt to load missing assemblys from subfolder
/// </summary>
private static Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
{
if (args.Name.StartsWith("CefSharp"))
{
resolved = true; // Set to true, so BrowserSubprocessPath will be set
string assemblyName = args.Name.Split(new[] { ',' }, 2)[0] + ".dll";
string subfolderPath = Path.Combine(Application.StartupPath, cefSubFolder, assemblyName);
return File.Exists(subfolderPath) ? Assembly.LoadFile(subfolderPath) : null;
}
return null;
}
}
}
And then in Visual Studio I use the following build events.
Pre-build:
RD /S /Q "$(ProjectDir)bin\$(PlatformName)\$(ConfigurationName)\CEFSharp"
Post-Build:
dir /b /a-d "$(ProjectDir)bin\$(PlatformName)\$(ConfigurationName)\"|findstr /b "$(TargetName)" >"%temp%\searchfiles.tmp"
mkdir CEFSharp
xcopy "$(ProjectDir)bin\$(PlatformName)\$(ConfigurationName)" "$(ProjectDir)bin\$(PlatformName)\$(ConfigurationName)\CEFSharp" /exclude:%temp%\searchfiles.tmp /y
cd "$(ProjectDir)bin\$(PlatformName)\$(ConfigurationName)\"
attrib +r $(TargetName).*
del /q *
attrib -r $(TargetName).*
move "$(ProjectDir)bin\$(PlatformName)\$(ConfigurationName)\locales" "$(ProjectDir)bin\$(PlatformName)\$(ConfigurationName)\CEFSharp"
move "$(ProjectDir)bin\$(PlatformName)\$(ConfigurationName)\swiftshader" "$(ProjectDir)bin\$(PlatformName)\$(ConfigurationName)\CEFSharp"
Even better, as @amaitland suggested modify your project to include CefSharpTargetDir before the CefSharp targets and the files will be copied to a subfolder as part of the build. See: https://github.com/cefsharp/CefSharp/blob/cefsharp/83/NuGet/CefSharp.Common.targets#L12
<PropertyGroup>
<CefSharpTargetDir Condition=" '$(CefSharpTargetDir)' == '' ">CEFSharp</CefSharpTargetDir>
</PropertyGroup>
