Business Layer With Active Record Pattern And Entity Framework

In this video I take you back to the basics. I show you how to build a business layer using Active Record pattern as the foundation. We will explore the downsides, and discuss challenges and benefits. We will use a .NET Core Console Application (sorry that I keep calling it an "ASP.NET Core" console, I have that on the brain) as the presentation to focus strictly on the design.
