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 Google Cloud Pub/Sub in C# with this .NET tutorial. Publish and subscribe to messages on GCP with runnable code examples. Start building today! If you're building distributed systems on Google Cloud Platform, Google Cloud Pub/Sub is the messaging backbone you'll reach for again and again. It's a fully managed, globally distributed publish/subscribe service that decouples the services that produce events from the services that process them — no brokers to patch, no clusters to scale, no partitions to rebalance. In this tutorial, you'll learn how to use Google Cloud Pub/Sub with C# and .NET: creating topics and subscriptions, publishing messages asynchronously, consuming them with the high-throughput streaming subscriber, and handling the real-world concerns — ordering, retries, dead-letter queues, and exactly-once processing — that separate a demo from a production system. What Is Google Cloud Pub/Sub and Why Use It? Pub/Sub implements the classic publish/s...
