How to Receive an SMS With Blazor and SignalR

When building an app to manage SMS messages with the Vonage Messaging API, receiving inbound SMS messages is crucial. This tutorial explores how to receive SMS messages in real-time using Blazor and SignalR Core. To achieve this, developers need a Vonage API account, the latest .NET Core 3.1 SDK, and either Visual Studio 2019, Visual Studio for Mac, or Visual Studio Code. The app uses a controller to receive inbound SMS webhooks from Vonage, which are then sent to all clients connected to an SmsHub using SignalR. The frontend displays incoming messages in a table, and the app is tested with ngrok to create a publicly accessible URL. By combining SignalR, Blazor, and the Vonage APIs, developers can build an app that watches SMS messages come into real-time.
