Handle custom protocol schemes when you are using the WebBrowser control in a Windows Forms (or WPF) desktop application.
ProtocolFactory.Register("rsrc", () => new ResourceProtocol());
var html = @"<html><body style=""background-image: url(rsrc:helloworld.png)""></body></html>";
Browser.DocumentText = html;The ResourceProtocol class in the example above implements the following interface to deliver embedded resources to the browser control:
public interface IProtocol
{
string Name { get; }
Task<Stream> GetStreamAsync(string url);
}
