  • What is missing is the badge [Preview] in the top right menu bar. Blazor doesn't work (well) on the regular VS2019 yet. – H H May 22 '19 at 09:21

Visual Studio 2019 official release doesn't yet have complete support for Blazor. (https://github.com/aspnet/AspNetCore/issues/10421)

Download the latest preview and re-follow the instructions on how to get started.
