本篇博客讲述如何在AnyCPU模式下使用CefSharp

因为在某些情况下，不得不用AnyCPU，但是CefSharp支持的是86和64位俩种模式，所以在我查阅了很多国内外的资料下，总结出来的一些精华

https://github.com/cefsharp/CefSharp/issues/1714

https://github.com/cefsharp/CefSharp.MinimalExample/blob/demo/anycpu/CefSharp.MinimalExample.Wpf/App.xaml.cs

三篇结合就可以实现在AnyCPU下使用CefSharp

简单步骤记录

第一篇博客取其第二个，更改配置的那一块，这块不改，下面的没用，项目起不起来

　　简述一下：

　　1.修改为首选32位，

　　2.在你项目名.csproj文件下，加一段

<CefSharpAnyCpuSupport>true</CefSharpAnyCpuSupport>

　　　　位置如下：

　　3.在App.config下加一端

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
        <probing privatePath="x86"/>
    </assemblyBinding>
</runtime>

　　　　位置如下：

第二篇博客取的精髓在这块，我给放过来

public partial class App : Application
{
    public App()
    {
        //Add Custom assembly resolver
        AppDomain.CurrentDomain.AssemblyResolve += Resolver;

        //Any CefSharp references have to be in another method with NonInlining
        // attribute so the assembly rolver has time to do it's thing.
        InitializeCefSharp();
    }

    [MethodImpl(MethodImplOptions.NoInlining)]
    private static void InitializeCefSharp()
    {
        var settings = new CefSettings();

        // Set BrowserSubProcessPath based on app bitness at runtime
        settings.BrowserSubprocessPath = Path.Combine(AppDomain.CurrentDomain.SetupInformation.ApplicationBase,
                                               Environment.Is64BitProcess ? "x64" : "x86",
                                               "CefSharp.BrowserSubprocess.exe");

        // Make sure you set performDependencyCheck false
        Cef.Initialize(settings, performDependencyCheck: false, browserProcessHandler: null);
    }

    // Will attempt to load missing assembly from either x86 or x64 subdir
    // Required by CefSharp to load the unmanaged dependencies when running using AnyCPU
    private static Assembly Resolver(object sender, ResolveEventArgs args)
    {
        if (args.Name.StartsWith("CefSharp"))
        {
            string assemblyName = args.Name.Split(new[] { ',' }, 2)[0] + ".dll";
            string archSpecificPath = Path.Combine(AppDomain.CurrentDomain.SetupInformation.ApplicationBase,
                                                   Environment.Is64BitProcess ? "x64" : "x86",
                                                   assemblyName);

            return File.Exists(archSpecificPath)
                       ? Assembly.LoadFile(archSpecificPath)
                       : null;
        }

        return null;
    }
}

第三篇博客就是告诉你using指令怎么引，以及详细的写法，要用的话，还是用第二篇博客的这段代码

using System;
using System.IO;
using System.Reflection;
using System.Runtime.CompilerServices;
using System.Windows;

namespace CefSharp.MinimalExample.Wpf
{
    public partial class App : Application
    {
        public App()
        {
            //Add Custom assembly resolver
            AppDomain.CurrentDomain.AssemblyResolve += Resolver;

            //Any CefSharp references have to be in another method with NonInlining
            // attribute so the assembly rolver has time to do it's thing.
            InitializeCefSharp();
        }

        [MethodImpl(MethodImplOptions.NoInlining)]
        private static void InitializeCefSharp()
        {
            //Perform dependency check to make sure all relevant resources are in our output directory.
            var settings = new CefSettings();
            settings.BrowserSubprocessPath = Path.Combine(AppDomain.CurrentDomain.SetupInformation.ApplicationBase,
                                                   Environment.Is64BitProcess ? "x64" : "x86",
                                                   "CefSharp.BrowserSubprocess.exe");

            Cef.Initialize(settings, performDependencyCheck: false, browserProcessHandler:null);
        }

        // Will attempt to load missing assembly from either x86 or x64 subdir
        // Required by CefSharp to load the unmanaged dependencies when running using AnyCPU
        private static Assembly Resolver(object sender, ResolveEventArgs args)
        {
            if (args.Name.StartsWith("CefSharp"))
            {
                string assemblyName = args.Name.Split(new[] { ',' }, 2)[0] + ".dll";
                string archSpecificPath = Path.Combine(AppDomain.CurrentDomain.SetupInformation.ApplicationBase,
                                                       Environment.Is64BitProcess ? "x64" : "x86",
                                                       assemblyName);

                return File.Exists(archSpecificPath)
                           ? Assembly.LoadFile(archSpecificPath)
                           : null;
            }

            return null;
        }
    }
}
