In this article, we’ll take a close look at some of the changes we made on this very site — running on JAMStack with React — to optimize the web performance and improve the Core Web Vitals metrics. With some of the mistakes we’ve made, and some of the unexpected changes that helped boost all the metrics across the board. 

This article will show you how to build your Web API with the new ASP.NET Core 3.0 and how to integrate with Auth0 in order to secure them. Following the steps described in this tutorial, you will end up building a simple Web API project

ASP.NET Core 1.0 (formerly ASP.NET 5) provides a revamped Web development framework geared towards the requirements of modern Web applications. The new framework, currently in RC1, requires you to learn many new concepts not found in ASP.NET MVC 5. To that end, this article enumerates a few important features that ASP.NET MVC 5 developers should know as they prepare to learn this new framework.
