Deep dives into .NET, AWS, Docker & Modern Architecture
CQRS, or Command Query Responsibility Segregation helps you build super clean and scalable systems with ease. In this article, we will explore this pattern, and use the MediatR package in ASP.NET Core to implement the CQRS Pattern and build a simple yet clean CRUD application in .NET! We will also look into how MediatR notifications work.
After nearly a decade of working with .NET, I’ve learned that writing great code is only part of the journey. The real growth comes from debugging tough issues, refactoring messy legacy code, and learning from mistakes the hard way. From best practices to real-world insights, here are 20 essential tips that will help you write cleaner, more efficient, and scalable .NET applications. Whether you're just starting out or have years of experience, these lessons will make you a better .NET developer.
With the release of .NET 9, you might have noticed that Swagger Gen is no longer included by default in web API templates. This means that when you create a new .NET 9 WebAPI, you no longer have the fancy green Swagger UI to test your API Endpoints. If you're wondering why and what this means for your projects, you're not alone! But don't worry—Microsoft has introduced a new way to handle API documentation that makes things even better.
