ASP.NET Core 3.0 Workshop

Documentation and samples for ASP.NET Core 3.0 workshop.

NOTE: Updated to final version of .NET Core 3.0!

Cover image

This workshop is intended as a walk-through into .NET Core and ASP.NET Core 3.0 features, creating a new Web API, preparing it for production use and consuming it from client-side Blazor client.

The workshop is partially based on my talk Building production-ready APIs with ASP.NET Core.

It's also inspired by .NET Presentations and workshops created by .NET Core and ASP.NET Core teams. Some content for presentations is borrowed from there, as well as the Power Point presentation templates. Just to be clear - it's not a fork of some existing ASP.NET Core workshop, but a new one, created from scratch. Sample code and instructions for all sessions below are created for this workshop specifically.

Getting started

This repository contains all the instructions and material that you need to follow the workshop by yourself, through a set of sessions / parts. Also, if you are attending the live workshop, but miss a day or two, you should be able to pick it up using the instructions provided.
