Roundup #55: .NET Core 3, F# 4.7, AWS joins .NET Foundation, .NET Foundation Maturity Model, Finding Service Boundaries

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.

Announcing .NET Core 3.0

We’re excited to announce the release of .NET Core 3.0. It includes many improvements, including adding Windows Forms and WPF, adding new JSON APIs, support for ARM64 and improving performance across the board. C# 8 is also part of this release, which includes nullable, async streams, and more patterns. F# 4.7 is included, and focused on relaxing syntax and targeting .NET Standard 2.0. You can start updating existing projects to target .NET Core 3.0 today. The release is compatible with previous versions, making updating easy.

Announcing F# 4.7

We’re excited to announce general availability of F# 4.7 in conjunction with the .NET Core 3.0 release! In this post, I’ll show you how to get started, explain everything in F# 4.7 and give you a sneak peek at what we’re doing for the next version of F#.

AWS Joins the .NET Foundation

We’re excited to announce today that AWS is joining the .NET Foundation as a corporate sponsor. AWS has a long-standing commitment to .NET, with a decade of experience running Microsoft Windows and .NET on AWSJoining the .NET Foundation is a natural step for us to further invest and participate in this community.

.NET Foundation Project Maturity Model

This proposal describes new approaches that we can use to improve the quality and quantity of .NET open source projects, and the .NET ecosystem generally. The .NET ecosystem is strong, but could be stronger still, and there are general challenges in open source projects that we should address in our ecosystem.

Context is King: Finding Service Boundaries Talk

Shameless plug of my own talk 🙂

Are you having trouble defining service boundaries? We know there are benefits in splitting up a complex system, such as more focused models and modular deployments.

Defining the correct service boundaries is incredibly important but can be pretty tricky. When defined correctly, the model feels natural and cohesive. Defined wrong can make a system overly complex and end in disaster.

Join Derek as he explores the use of key terminology in real business systems. How dissecting simple words and asking the right questions led to insights that helped define the service boundaries in real business systems developed over the last decade.
