ASP.NET Core - Run multiple web applications within parent application

Hi All,

I need to create a "shell" parent ASP.NET Core web application where authentication will be handled and then run many other web applications within the parent application. All child applications should be rendered within parent application. I am not sure how to accomplish it. I suppose that I have to use Kestrel in parent webapp? Not sure. Tried to find any help on the net, without success. 

Any support or sample project will be really appreciated.

Thank you in advance!
