Paypal Ipn integration with asp.net MVC

Question

HomeControler/Index.cshtml page is as below

Answer 1

If I remember correctly, the IPN is an asynchronous call that can come at anytime after the transaction (its generally "instant", sometimes not so much). But this comes from PayPal, who cannot access http://localhost. To test IPN you need to deploy to an actual internet site that anyone can access. It's been a few years since I worked with IPN - but that was my general experience. Setup some logging in your application, publish, then do your test transactions.

EDIT:

Also - I think you can give it your WAN IP address (not local), open up the ports in your router, and instead use that IP address (note you may need to enable remote connections with IIS Express - see IIS Express enable external request):
