Learn how to enforce HTTPS in ASP.NET Core with SSL, HSTS, and redirection. Secure your web app with this step-by-step C# tutorial. Start now! If you're building a web application, securing it with ASP.NET Core HTTPS is no longer optional — it's a baseline requirement. Browsers flag plain HTTP sites as "Not Secure," search engines penalize them, and attackers actively exploit unencrypted traffic on public networks. The good news? ASP.NET Core ships with built-in middleware to enforce SSL, redirect insecure requests, and harden your app with HSTS. In this tutorial you'll learn exactly how to enforce HTTPS in ASP.NET Core, why each setting matters, and the common pitfalls that trip up even experienced developers. Whether you're a beginner wondering how to enable SSL, an intermediate developer searching for best practices, or a senior engineer hardening a production deployment, this guide covers the full picture — from development certificates to product...

Learn authentication vs authorization in ASP.NET Core with practical C# code, JWT, and policy examples. Secure your .NET apps the right way—start now. If you are building secure web APIs or web apps in .NET, understanding authentication vs authorization in ASP.NET Core is the single most important security skill you can master. These two concepts are constantly confused—even in production code reviews—yet they protect completely different things. Authentication answers "Who are you?" while authorization answers "What are you allowed to do?" Get them wrong, and you ship either a locked-out app or a data breach waiting to happen. In this complete security guide, you'll learn exactly how ASP.NET Core authentication and authorization work under the hood, see runnable C# code for JWT, role-based, and policy-based access control, and walk away with the best practices and common pitfalls that senior .NET engineers use to keep apps secure. Authentication ...

Learn how to run local AI with Ollama and C#. Set up free local LLMs on your own machine with runnable code examples. Start building offline AI apps today. Want to build AI features without paying per API call or shipping your users' data to a cloud provider? Running local AI with Ollama and C# lets you host large language models (LLMs) directly on your own machine — completely free, fully offline, and privacy-first. In this tutorial you'll learn how to run an LLM locally in C#, call it from your .NET applications, stream responses, and build production-ready patterns that scale. Whether you're a beginner searching for "how to run LLM locally" or a senior engineer evaluating self-hosted AI for C#, this guide has runnable code and the reasoning behind every decision. Why Run Local AI with Ollama and C#? For most of the last few years, adding AI to a .NET app meant calling a hosted API. That works, but it comes with three persistent problems: cost (you pa...
