How to display a web page by CefSharp.Wpf browser control with local file resources

Thanks to amaitland for leading me to the right direction:

I strongly advise against using file:/// when loading from local disk. Different security restrictions apply and there are many limitations. I'd suggest using a Scheme handler or implementing your own IResourceRequestHandlerFactory. (Loading a data: encoded URI is also pretty handy, specially for the OffScreen project). If you choose to ignore this advice you'll have to resolve any issues you have using file:/// yourself. ceforum is the best resource.

The solution is to create a custom scheme handler:

https://github.com/cefsharp/CefSharp/wiki/General-Usage#scheme-handler

1) I addeded angular, bootstrap and jquery files as resources to my visual studio project.

2) I created DiskSchemeHandlerFactory.cs:

public class DiskSchemeHandlerFactory : ISchemeHandlerFactory
{
    private static readonly string _SchemeName = "disk";
    private static readonly IDictionary<string, string> _ResourceDictionary;


    public string SchemeName
    {
        get { return _SchemeName; }
    }


    static DiskSchemeHandlerFactory()
    {
        _ResourceDictionary = new Dictionary<string, string>
        {
            { "/angular.min.js", Properties.Resources.angular_min },
            { "/angular.min.js.map", Properties.Resources.angular_min_js },
            { "/bootstrap.min.js", Properties.Resources.bootstrap_min1 },
            { "/bootstrap.min.css", Properties.Resources.bootstrap_min },
            { "/jquery.min.js", Properties.Resources.jquery_min }
        };
    }


    public IResourceHandler Create(IBrowser browser, IFrame frame, string schemeName, IRequest request)
    {
        //Notes:
        // - The 'host' portion is entirely ignored by this scheme handler.
        // - If you register a ISchemeHandlerFactory for http/https schemes you should also specify a domain name
        // - Avoid doing lots of processing in this method as it will affect performance.
        // - Uses the Default ResourceHandler implementation

        var uri = new Uri(request.Url);
        var fileName = uri.AbsolutePath;

        string resource;
        if (_ResourceDictionary.TryGetValue(fileName, out resource) && !string.IsNullOrEmpty(resource))
        {
            var fileExtension = Path.GetExtension(fileName);
            return ResourceHandler.FromString(resource, fileExtension);
        }

        return null;
    }
}

3) I modified the static constructor of MyWebBrowser.xaml.cs:

    static MyWebBrowser()
    {
        if (Cef.IsInitialized == false)
        {
            var diskSchemeHandlerFactory = new DiskSchemeHandlerFactory();

            var settings = new CefSettings();
            settings.RegisterScheme(new CefCustomScheme()
            {
                SchemeName = diskSchemeHandlerFactory.SchemeName,
                SchemeHandlerFactory = diskSchemeHandlerFactory
            });

            Cef.Initialize(settings);
        }
    }

4) Finally I changed the file paths of the html page:

<script src="disk://angular/angular.min.js"></script>
<script src="disk://jquery/jquery.min.js"></script>
<script src="disk://bootstrap/bootstrap.min.js"></script>

Maybe I modify it to work with full file paths too. With this solution I have to compile my project each time I want to use another file...
