web api in .net core

Regarding learning core ,Below you find a link to download a simple program on MVC core.

 * The idea of the program is very simple, which is to identify the types of vaccines, record those who want to be vaccinated, schedule and report to the registrars.(Currently, the notification does not work, but only a message shows that it will be reported by phone or mail)

 * The reason why the software was simplified is that I was aiming through it to apply some design patterns and design principles

 - The pattern used for storage purposes is the Repository   Pattern 

  -The pattern used for defining various reporting mechanisms is the Adapter Pattern

  -The pattern used for defining for notifying registrars is the Observer Pattern

Notes

1.

--The API for checking user data(i.e. if telephone number is valid) should be downloaded  from the next link

--The API should be run with the program at the same time  or it will not be able to register those wishing to receive the vaccine.

--The purpose of this API is to 

    ->demonstrate how Web API is called

       ->demonstrate using Single Responsibility Principle through classifying methods needed to call the API into different classes

 and
