In the “Create New ASP.Net Core Web Application” window, select .NET Core as the runtime and ASP.NET Core 2.2 (or later) from the drop-down list at the top. I’ll be using ASP.NET Core 3.0 here.

API Analyzers, introduced with ASP.NET Core 2.2, enable you to follow a set of conventions to improve the documentation of the APIs of your ASP.NET Core applications.
