I need sample of NTier architecture codebase in asp.net core

Dear All,

Please I am new to asp.net core. I am trying to use the NTIER Architecture model in my asp.net core project. Al the tutorials that I have seen dont follow this model.

I have been able to seperate my POCO class layer, So I also want my DAL Layer to be seperate so that other applications in my project can import it and use it.

Example is my web apis, web job codes should be able to call this DAL Layer library to use this. Would like the Database context to be in the DAL Layer library too.

So in summary I just need the the structure so I can work, without having problem when adding migration and updating database.

Please kindly paste any link so I read up 

Thanks alot.
