}WPF panels arrange elements in rectangular areas and most WPF elements have rectangular shape. HexGrid project started as an attempt to create a custom shaped control and evolved into a hexagonal control and a panel which can arrange them.
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.

This article dives into the mock questions I would ask, along with responses that are my personal best guess to the answers. Could my answers not reflect actual opinions shared by the team at Microsoft? Sure, but I'm hoping folks from the .NET team can jump in to correct me if I am way off base.
This is a rather interesting time for .NET – what's being done shapes the future of .NET for the next decade. Let's ask the honest questions and hopefully all of us will understand the new .NET ecosystem a little better.
This article will show you how to implement a reverse proxy in C# and .NET Core to overcome specific needs that you could hardly solve with an out-of-the-box software. You can find the code of the final project on this GitHub repository.
MauiReactor is a component-based UI Library built on top of .NET MAUI that enables you to build applications with code first MVU component based architecture. James has Adolfo, the libraries creator, on to talk about the project and show off some stunning UI.
.NET apps can now run natively on Windows ARM64. This follows the support we added for Linux ARM64 in .NET Core 3.0. With .NET 5.0, you can develop web and UI apps on Windows ARM64 devices, and deliver your applications to users who own Surface Pro X and similar devices. You can already run .NET Core and .NET Framework apps on Windows ARM64, but via x86 emulation. It’s workable, but native ARM64 execution has much better performance.
