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 ransomware protection best practices for developers. Secure your C# apps and data with proven coding techniques and prevention strategies. Ransomware Protection for Developers — How to Secure Your Apps and Data Ransomware protection is no longer just a concern for IT administrators and security teams. As a developer, the code you write is either part of the solution or part of the attack surface. In 2026, ransomware attacks cost businesses over $30 billion globally, and a significant number of breaches exploited vulnerabilities in application code — insecure file uploads, unvalidated inputs, hardcoded credentials, and weak encryption. If you build software in C# or .NET, this guide will show you exactly how to harden your applications against ransomware threats with practical, runnable code examples. This article covers ransomware prevention from a developer's perspective: secure coding practices, data protection, file integrity monitoring, backup automation, and...
