I'm not sure what specifically you want to achieve? Is it a student project for demo? Anyways I can suggest you following: you can create your own seperate projects for database access layer in Entity Framework and let's say your SQL server or any other databse is hosted on different server in your network. So this makes one tier. This DB project only has logic of CRUD operations nothing else. Lets say on top of it you create seperate project - C# class library project for business logic that contians some business rules and related logic this can be considered another tier. Let's say now you create a WCF project or Web API project that exposes this service layer over interner. this becomes another tier. Now to consume it and show user some UI you create WPF/ASP.Net project and use the WCF or Web API in it. this becomes another tier. for som examples I suggest following: https://www.codeproject.com/Articles/32237/N-Tier-development-with-ASP-NET-MVC-WCF-and-LINQ https://www.codeproject.com/Articles/434282/A-N-Tier-Architecture-Sample-with-ASP-NET-MVC-WCF https://www.codeproject.com/articles/26826/northwind-n-tier-blueprint-application-using-wpf-w https://www.codeproject.com/Articles/294022/Walkthrough-Creating-an-N-tier-Data-Application-wi
