Custom IRenderProcessHandler implementation

[SorceryAdmin]

hello I have been able to use SelfHost example to get cef browsersubprocess rename to my custom process name ,
I tried to add a Custon IRenderProcessHandler but is never called I even put some log creation ton the on OnContextCreated and they are never created.
what I did was in the main:

        var exitCode = SelfHost.Main(args);
        if (exitCode >= 0)
        {
            return exitCode;
        }
        if (args.Length > 5)
        {
            //	SubProcess.EnableHighDPISupport();

            //Add your own custom implementation of IRenderProcessHandler here
            IRenderProcessHandler handler = new MyRenderHandler();
            //The WcfBrowserSubprocessExecutable provides BrowserSubProcess functionality
            //specific to CefSharp, WCF support (required for Sync JSB) will optionally be
            //enabled if the CefSharpArguments.WcfEnabledArgument command line arg is present
            //For .Net Core use BrowserSubprocessExecutable as there is no WCF support
            var browserProcessExe = new BrowserSubprocessExecutable();
            var result = browserProcessExe.Main(args, handler);
            return 1;
        }

...
then 
            settings.BrowserSubprocessPath = System.AppDomain.CurrentDomain.BaseDirectory + System.AppDomain.CurrentDomain.FriendlyName + ".exe";

You need to attach the debugger to the render process instances. See https://www.chromium.org/developers/how-tos/debugging-on-windows/#multi-process-issues

Generally I just attach using the manual method.

the issue is not that is multiprocess, I put

File.WriteAllTextAsync(InstancelogsPath+$"{DateTime.UtcNow.Ticks}_log.txt", $"Context created for frame: {frame.Url}\nBrowser ID: {browser.Identifier}\nFrame ID: {frame.Identifier}\nTimestamp: {DateTime.Now}\n");

and no file is ever created, I'm unable to make the browser use the custom IRenderProcessHandler

Closer look at your code and it's not quite correct. You cannot use SelfHost.Main if you want to pass in a render process handler currently.

using CefSharp.Internals;

var type = CommandLineArgsParser.GetArgumentValue(args, CefSharpArguments.SubProcessTypeArgument);

if (!string.IsNullOrEmpty(type))
{
  IRenderProcessHandler handler = new MyRenderHandler();
  var browserProcessExe = new BrowserSubprocessExecutable();
  return browserProcessExe.Main(args, handler);
}

//Launch main process as normal.

You can programmatically launch the debugger which is useful for troubleshooting.
