There’s a ton of small bug fixes in this release, quite a few enhancements and a few larger new features. Configuration performance went up quite a bit, and I’ve laid the groundwork to make in-memory mapping a lot faster in the future. LINQ projection has gotten to the point where you can do anything that the major query providers support.
A list of C# Source Generators (not necessarily awesome), because I haven't found a good list yet.
C# Source Generators is a Roslyn compiler feature introduced in C#9/.NET 5. It lets C# developers inspect user code and generate new C# source files that can be added to a compilation.
Visual Studio Code, ever growing in popularity and flexibility, has been named by Google as a first-class code editor for working with the company's Flutter SDK and Dart programming language for mobile development.
Domain Driven Design: The Good Parts
The greenfield project started out so promising. Instead of devolving into big ball of mud, the team decided to apply domain-driven design principles. Ubiquitous language, proper boundaries, encapsulation, it all made sense.
But along the way, something went completely and utterly wrong. It started with arguments on the proper way of implementing aggregates and entities. Arguments began over project and folder structure. Someone read a blog post that repositories are evil, and ORMs the devil incarnate. Another read that relational databases are last century, we need to store everything as a stream of events. Then came the actor model and frameworks that sounded like someone clearing their throat. Instead of a nice, clean architecture, the team chased the next new approach without ever actually shipping anything.
Beyond the endless technical arguments it causes, domain-driven design can actually produce great software. We have to look past the hype into the true value of DDD, what it can bring to our organizations and how it can enable us to build quality systems. With the advent of microservices, DDD is more important than ever - but only if we can get to the good parts.
As software creation processes continue to become more complicated, development teams are taking a more all-encompassing approach that involves agile testing methodologies. Like agile software development, agile testing involves running test cases that assess the overall integrity of a solution, rather than simply ensuring that each part and piece are technically sound. Viewed as an analogy, agile testing methodologies ensure that software is a well-oiled machine, whereas a linear approach to testing just ensures that each of the gears is in good order. Herein lies the difference between unit tests and test automation.
C# for Beginners
Join Scott Hanselman and .NET Distinguished Engineer David Fowler as they teach us C# from the ground up! From Hello World to LINQ and more, Scott and David share C# lessons at a deep and leisurely pace. By the end you'll be ready to explore the Foundational C# Certification from FreeCodeCamp!
This project intends to provide a complete description and
re-implementation of the WhatsApp Web API, which will eventually lead to
a custom client. WhatsApp Web internally works using WebSockets; this
project does as well.
