Learn Azure AI Search with C# — index data, run vector and hybrid queries, and add RAG to your .NET app. Start building intelligent search today. If your application's search box still runs a LIKE '%term%' query against SQL Server, your users are quietly suffering. They type "cheap laptop for uni" and get zero results because your catalogue says "affordable notebook for students." Azure AI Search with C# fixes exactly this problem: it combines classic keyword search, vector embeddings, and semantic reranking into a single managed service that you can drive from .NET with a few dozen lines of code. In this tutorial you'll build a working search index from scratch, run keyword, vector, and hybrid queries, and finish with a Retrieval Augmented Generation (RAG) pattern that grounds an LLM in your own data. This guide targets .NET 9 and the Azure.Search.Documents v11 SDK. Every snippet is runnable. We'll explain why each design choice matter...
Learn Azure Service Bus with C# in this hands-on tutorial. Master queues, topics, and event-driven architecture with runnable .NET code examples. Start now! If you are building distributed systems on Microsoft's cloud, learning Azure Service Bus with C# is one of the highest-value skills you can add to your toolkit. As applications move away from monolithic designs toward microservices and event-driven architecture, a reliable message broker becomes the backbone that keeps services loosely coupled, resilient, and scalable. In this Azure Service Bus tutorial, you'll learn exactly how to send and receive messages using queues and topics with the modern Azure.Messaging.ServiceBus .NET SDK, understand why asynchronous messaging matters, and avoid the pitfalls that trip up most developers. Whether you're a beginner searching "how to use Azure Service Bus," an intermediate developer looking for best practices, or a senior engineer designing advanced event-drive...
