My personal training to learn more about different ways to test .NET Core. But instead, I am using .NET Core 2.2 here.

This will need to be updated to .NET Core 3.x.

This project includes couple of approaches to implement certain feature.

Please find below if you'd like to also learn more from the same course.

The future changes will be to modify this to .NET Core 3.0
