Rate limiting is a technique used to control how many requests a client can make to an API within a certain timeframe. In this article, we will explore how to implement rate limiting in .NET Minimal APIs using the built-in middleware, focusing on the Fixed Window strategy and applying limits per endpoint.

API key authentication is a common approach to securing APIs by requiring clients to provide a unique key with each request. In this article, we will explore how to implement API key authentication in .NET Minimal APIs while supporting multiple API keys.

Minimal APIs, the streamlined, lightweight approach to creating APIs in .NET, offer a perfect blend of simplicity, flexibility, and power. Whether you’re new to API development or a seasoned developer looking to refine your skills, this course has everything you need to take your expertise to the next level.

In this post, we take a look at a brand new feature released with C# 12 and .NET 8, called Primary Constructors - a thing we already have for Records but that is now extended to Classes and Structs.

In this article, we will explore the options pattern and how it helps us to have the ability to separate the settings (configurations) for different parts of our applications. We will also take a look and how we can validate our settings as well as mock or create them for the various test cases of our applications.
