Client Streaming with SignalR in ASP.NET Core

Real-time web applications often require more than just instant server-to-client updates. When your application needs to send continuous streams of data from the client to the server—such as uploading sensor telemetry, sending voice snippets, or transmitting real-time user inputs—traditional HTTP requests fall short. This text-based course guides you through the process of building robust, bi-directional streaming pipelines using SignalR. You will start with the fundamental concepts of real-time communication, understand how streaming differs from standard hub methods, and learn how to configure your ASP.NET Core backend to receive continuous data streams. What you'll learn: Understand the core architecture of SignalR streaming and how it manages connection channels; Configure hub methods in ASP.NET Core specifically designed to accept streaming data sources; Implement client-side streaming senders using both JavaScript and .NET clients; Manage stream life cycles, including connection state, cancellation tokens, and error handling; Apply modern performance practices such as backpressure management and asynchronous stream processing using System.Threading.Channels. The course begins with foundational definitions and network concepts before guiding you through step-by-step implementation patterns for both backend APIs and frontend clients. This course is designed for backend developers, web engineers, and .NET enthusiasts who are already familiar with basic C# and ASP.NET Core but are new to real-time streaming architectures.
