How to organize a solution of three projects on ASP Core?

Question

ASP.NET

I want to create a project on a new technology, but got into a stupor from the very beginning.
Created a solution
from three projects
Core - class library
Presentation - ASP core empty project
Admin - ASP core empty project
I wanted to display Startup and Program.cs in the Core project. does not exit, since it cannot be made executable - this is the first question.
The second is how to separate controllers and views into different projects, so that in the Admin project - he created a controller and he hooked views from this project, and also from the Presentation project
Thank you in advance for your answers
