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 AWS CloudFormation with C# to automate cloud infrastructure. Step-by-step tutorial with code examples using AWS CDK and SDK for .NET. AWS CloudFormation with C# — Automate Your Cloud Infrastructure AWS CloudFormation with C# lets you define, deploy, and manage your entire cloud infrastructure using the language you already know. Instead of clicking through the AWS Console or writing JSON/YAML templates by hand, you can use strongly-typed C# code to provision S3 buckets, Lambda functions, DynamoDB tables, and hundreds of other AWS resources — all with IntelliSense, compile-time checks, and the full power of .NET. In this tutorial, you will learn two powerful approaches: using the AWS CDK (Cloud Development Kit) to define infrastructure as C# code, and using the AWS SDK for .NET to manage CloudFormation stacks programmatically. By the end, you will be able to automate your AWS deployments entirely from C#. Why Use C# for AWS CloudFormation? If you are a .NET deve...
