Create RestPortal as alternative to WcfPortal

I am exploring the idea of creating a RestPortal based on WcfPortal to simplify creating a Web API for HTML + Angular client. WcfPortal has quite a simple API: Create, Delete, Update, Fetch, which should be easy to duplicate in a Web API. Any thoughts on pros and cons of this? Any pointers on how could simplify project or roadblocks may encounter?

Thanks, Kurt
