I had intended to write this site using Blazor and ASP.NET Core 3.0  but given that I experienced formatting problems with Bootstrap 4 markup, and since I also couldn't get some of the Telerik UI components to work (perhaps not surprising since Blazor, ASP.NET Core 3 and the Telerik components are all in Preview) I decided to stick with ASP.NET Core 2.2 for the time being.
