Creating the Blazor Web Assembly project

In the previous project, we learned how to create a web app with basic functionalities such as fetching and updating records via a web API call. In this project, we will build the frontend Progressive Web Application (PWA) to create a new record. This process is executed by invoking an API endpoint to post data and sends an event to Hub to automatically update the Blazor Server UI in real time when a new record is submitted.

Here's an attempt showing how the process works:

The preceding diagram shows the high-level process of how the real-time functionality works. The steps are pretty much self-explanatory, and it should give you a better understanding of how each application connects to one another. Without further ado, let's start building the last project to complete the whole application.
