These sessions will focus mainly on how to use NET Core to produce solid code following various well known patterns and practices. We will not have any Powerpoints or other kind of presentation material except plain code samples because these sessions are only about, coding!

NET Core 3.x Extensions library which is the current LTS version has been heavily refactored since versions 2.x and these sessions are for all of you that have used the older versions but also if you haven't been in contact at all with NET Core before.

In this first session I will show you the basics of some of the building blocks included in NET Core Extensions to get you up to speed using them.

In session two we will have a deeper look into NET Core. We will look at Entity Framework Core using Code First and also how to write your own extensions in a simple way.

Session three we will play around a bit with what we have seen and do some kind of rounding up of what you have seen. Finally we will have a brief look at NET 5 and what differs from earlier versions, we will also look at the future of NET and discuss Microsoft's plans regarding updates and lifecycle.

1. Various Host samples

   These samples are here just to show a variety of different applications you can make by using Microsoft.Extensions just to show their common base.
