CefSharp with Any CPU fails to display browser

First up, I'm fairly new to .NET and C# and this is a project to learn C# and CEF at the same time.

I have followed a number of tutorials from the net as well as looking into the CefSharp examples to create a WinForms application.

I have installed CefSharp.WinForms 53.0.1 from NuGet, and my project is using Any CPU (CefSharp 51+ has Any CPU support).

To achieve this I largely followed the tutorial from Ourcode (http://ourcodeworld.com/articles/read/173/how-to-use-cefsharp-chromium-embedded-framework-csharp-in-a-winforms-application). I made the changes for Any CPU as suggested and included the basic code to load google.

Everything builds fine, but when the form displays there's no browser shown, just a blank form.

If I set the target to x64 or x86, then the browser displays as expected.

I notice in the Ourcode comments that user Edek Halon has had the same issue, but no solution seems to be provided. Edek, has the same setup as me, so I wonder if this is an issue in 53.0.1? Potentialy Joey De Vries in the comments has the same issue.

The addition of support for Any CPU in CefSharp is covered in this GitHub issue : https://github.com/cefsharp/CefSharp/issues/1714

There is a troubleshooting page for CefSharp (https://github.com/cefsharp/CefSharp/wiki/Trouble-Shooting) and it seems a bit contradictory. Under General Troubleshooting

1) Platform Target You must select either x86 or x64 when using the NuGet packages. If you select AnyCPU the NuGet magic won't work currently.

Does CefSharp need to be built from source for Any CPU to work?

Just if anyone is having difficulties with this, follow the Github Tutorial at the following link : https://github.com/cefsharp/CefSharp/issues/1714

Basically the code should be as follows (Winforms Example):

 CefSharpSettings.SubprocessExitIfParentProcessClosed = true;
 Cef.EnableHighDPISupport();
 CefSettings settings = new CefSettings
        {
            CachePath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "CefSharp\\Cache"), //By default CefSharp will use an in-memory cache, you need to specify a Cache Folder to persist data
            BrowserSubprocessPath = @"x86\CefSharp.BrowserSubprocess.exe"
        };
        Cef.Initialize(settings, performDependencyCheck: true, browserProcessHandler: null); // Initialize cef with the provided settings            
        chromeBrowser = new ChromiumWebBrowser("http://ourcodeworld.com"); // Create a browser component            
        this.Controls.Add(chromeBrowser); // Add it to the form and fill it to the form window.
        chromeBrowser.Dock = DockStyle.Fill;
