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.

The generic term ASP.NET Core covers several frameworks for the web. Blazor, the most modern, is further divided into four variants.

The fourth preview version of .NET 10.0 mainly delivers improvements for web APIs based on ASP.NET Core and the web front-end framework Blazor.
