Understanding the goal of what we are going to build using various technologies

As we've learned from the previous section, Blazor is only a framework for building UIs. To make learning Blazor fun and interesting, we are going to use various technologies to build a whole web application to fulfill a goal. That goal is to build a simple data-driven web application with real-time capability using cutting-edge technologies: Blazor Server, Blazor WASM, ASP.NET Core Web API, SignalR, and Entity Framework Core.

• A Web API app that...
