ASP.Net Core CRUD Operation

Hi All,

I wanna build multi layer application by using ASP.Net core(only windows only) and Entity Framework Core, perhaps am bit struck-up while accessing layered object.

Layer:

• Business: Class library
• Data: Class Library
• Web: ASP.Net Core(Windows) 
• Default Dependency Injection(AddScoped) 

I would be much appreciate if share any stuff to refer.

Thanks,
