Roundup #48: .NET Reunified, Performance in .NET Core 3, XAML Hot Reload, Blazor

Here are the things that caught my eye recently in .NET.  I’d love to hear what you found most interesting this week.  Let me know in the comments or on Twitter.

.NET Reunified: Microsoft’s Plans for .NET 5

When Microsoft announced .NET 5 at Microsoft Build 2019 in May, it marked an important step forward for developers working across desktop, Web, mobile, cloud and device platforms. In fact, .NET 5 is that rare platform update that unifies divergent frameworks, reduces code complexity and significantly advances cross-platform reach.

What’s new for performance in .NET Core and ASP.NET Core 3.0 – Ben Adams

One of the biggest advantages of using .NET Core (besides cross-platform support) is the drastic improvements in performance. Because the .NET Core team was able to make minor breaking changes in the runtime and Base Class Library (BCL), lots of stuff was implemented much more efficiently. In this session Ben will dive into the performance improvements in .NET Core in the 3.0 release: runtime changes, JIT changes, intrinsics and a deep dive into some of the improvements making it the best release yet!

Announcing XAML Hot Reload for Xamarin.Forms

Today at Xamarin Developer Summit, we announced XAML Hot Reload for Xamarin.Forms, which enables you to make changes to your XAML UI and see them reflected live, without requiring another build and deploy.

XAML Hot Reload for Xamarin.Forms speeds up your development and makes it easier to build, experiment, and iterate on your user interface. And this means that you no longer have to rebuild your app each time you tweak your UI – it instantly shows you your changes in your running app!

Blazor, a new framework for browser-based .NET apps – Steve Sanderson

Today, nearly all browser-based apps are written in JavaScript (or similar languages that transpile to it). That’s fine, but there’s no good reason to limit our industry to basically one language when so many powerful and mature alternate languages and programming platforms exist. Starting now, WebAssembly opens the floodgates to new choices, and one of the first realistic options may be .NET.

Blazor is a new experimental web UI framework from the ASP.NET team that aims to brings .NET applications into all browsers (including mobile) via WebAssembly. It allows you to build true full-stack .NET applications, sharing code across server and client, with no need for transpilation or plugins.

In this talk I’ll demonstrate what you can do with Blazor today and how it works on the underlying WebAssembly runtime behind the scenes. You’ll see its modern, component-based architecture (inspired by modern SPA frameworks) at work as we use it to build a responsive client-side UI. I’ll cover both basic and advanced scenarios using Blazor’s components, router, DI system, JavaScript interop, and more.
