It's a new age for .NET developers. You can build cross-platform apps, use lighter tools like VS Code, and deploy instantly using tools like Docker. In fact, ASPNET Core and EF Core are so cross-platform that not only can you deploy your apps to OSX and Linux (oh, and Windows, too), but you can even build them on any of the platforms. In this session, Julie Lerman will add EF Core into an ASP.NET Core WebAPI, connect to PostgreSQL, and use the web API to interact with the data. And just because she can, Julie will do all of this coding, debugging, and running in OSX on a MacBook. You'll also see how EFCore's new InMemory provider makes unit testing a breeze. Once the API is tested and working, you'll see how to push the database and the new API into docker containers and run them on Linux.
