.NET Conf 2017 was all about .NET Core and .NET Standard (there were talks about Xamarin and stuff, but that's not as exciting). Also, I had my first live coding stream recently.
My first twitch.tv live stream was titled "Building a .NET Core Application with Onion Architecture". During the stream I went through the process of creating an application, developing each layer of the onion, discussing what I was doing along the way, and dropping some .NET Core, ASP.NET Core and EF Core knowledge on the viewers along the way.
