I have a client that has a PHP site, but the developer told him that he could not do the database with his system. He asked me to make a system for him that had a CRUD as a client. Since he has a contract with the company that developed his site, there's no way I can manage his website. It uses UolHost to host your site, its platform is in Linux, but I have seen that it is possible to switch to Windows, which has ASP.Net support.
Can I host my system in ASP.Net MVC, along with its website made in PHP and use the same domain?
