Introduction:

In this article, I walk you through "Azure SignalR Service" using Buyer-Supplier sample application. Azure SignalR service provides a real time communIcation between your applicatrion/pages.

We will cover couple of more Azure Services like Azure Functions, Azure Service Bus & Azure SQL Database. We will have one Buyer application in Asp.net core Razor Forms and ONE Supplier application in Asp.net core MVC.

Prerequisites: Azure Account for setting up Azure Services (SignalR, Functions, Service Bus etc) Visual Studio 2019 (For buyer and supplier application)

Application Flow:
        Buyer Application - Buyer will create an order for an item with quantity.
        Supplier Application - Supplier will get notified (A prompt message on his screen) that a buyer has added a new order.
        Supplier Application - Supplier will approve or reject the buyer orders.
        Buyer Application - Buyer will get notified on his screen that supplier has approved/rejected his order.

        The notification(Buyer/Supplier) will get triggered by Azure SignalR Service. It means we will be registerting our application/pages to the SignalR service

Project Structure:

        1. Entities - Contains a class "ActiveOrder" which is used for storing the active orders data from UI and Database         2. Common - Here we have AppSettings.cs class, it used for storing the appSettings values from app.config files in #5 UI projects
        3. DB - DB Schema and Stored Procedures used in application
        4. OrderPRocessingFunctionApp - Azure Function application
        5. UI - Buyer and Supplier - Client applications, one is for buyer and one is for supplier

Design/Flow:

Buyer:

Supplier:
