ASP.NET Core WebUI and WebAPI relations
<p>I have a solution which has 2 projects: WebUI and WebAPI.</p>

<ul>
<li>WebUI: There is only FroneEnd part with Angular2. It doesn't know about database.</li>
<li>WebAPI: This is RESTful API's which has database connection string and services.</li>
</ul>

<p>Question: Can anybody describe how I can make requests from WebUI to WebAPI in a CORRECT way. Set default ports, links, use configuration or else.
Thanks =)</p>
