Committee Updates

Outreach Comittee

We have two working groups that were kicked off in April's Outreach group meeting. One is working to determine the best way to support remote meetups, the second is a meta proposal group that is working on determining the process for getting Outreach proposals resourced and approved. Please see those two Github issues for details, and weigh in if you have something to share. We will have an update on next steps for both committees by out next meeting.

BuildStuff Weekly Virtual Meetups

Build Stuff offers free weekly meetups on various topics. On April 23, for example, Julie Lerman, author of the highly acclaimed “Programming Entity Framework” books, talked about her latest experiment on publishing a serverless ASP.Net Core API application onto AWS Lambda. That same meetup had Ian Cooper, founder of the London .NET Users Group, talking about messages in a distributed system.

.NET Foundation Project Updates

NUnit.Analyzers 0.2.0

Try out our first release ever of NUnit.Analyzers! By referencing this new NuGet package whenever you reference NUnit, you will get live, NUnit-specific diagnostics and code fixes in your IDE. Here are some of the smarts it currently provides:

  • Proper usage of the TestCaseAttribute
  • Proper usage of ParallelScopeAttribute
  • Translation of assertions written in the classic model into the constraint model
  • Proper usage of some of the most-used assertions (Is.EqualTo, Is.SameAs, Has.Count, Has.Property(...), Is.Null)

The full list of diagnostics is here. If you have ideas or problems, please let us know.

A big thank-you to Mikkel Nylander Bundgaard who has been leading this effort, and to the contributors who helped with this release: Ace Olszowka, Jason Bock, Jason Curl, Johan Larsson, Julian Verdurmen, Maxime Rouiller, Mihály Gyöngyösi, Oleksandr Liakhevych, and Steven Weerdenburg. This is an exciting step!

Marten

Marten team is currently working on the design of the new major (v4) release. The main focus will be put on the Event Sourcing part, but there will be also significant work done to make Marten more modular, efficient and easier to contribute. There is also a growing idea about using the code generation to reduce the boilerplate code.

For all that would like to see what's coming or take part in the discussions - there is a chance to contribute to the Design plan or the details of the upcoming Event Sourcing imrovements.

BenchmarkDotNet

BenchmarkDotNet v0.12.1 has been released!

.NET 5 support, perfolizer adoption, cross-platform disassembler, EventPipe-based cross-platform profiler, new fluent API, ref readonly support, and dozens of bug fixes! You can find more details in the official changelog.

Nancy is no longer being maintained!

We would like to thank all the thousands of users of Nancy, all the people who wrote blog posts, conference speakers, video producers and those that spread the word of Nancy.

We would like to thank the 150+ contributors to Nancy that made it what it became, without you the work would have been much harder and opportunities missed.

We would like to thank VQ for financially sponsoring our open source efforts.

We would like to thank the core contributors to Nancy @jchannon, @khellang, @damianh, @phillip-haydon, @prabirshrestha, @horsdal for working hard into the nights coding, testing and writing docs but most importantly the founders of Nancy itself @thecodejunkie and @grumpydev whose vision made Nancy what it was, a fun, performant and enjoyable web framework.

We understand that organisations may have services and products that still depend on Nancy in production. A couple of members of the team can offer support, maintenance, and migration services on commercial terms. Please reach out to nancyfx.help@gmail.com to discuss options.

Meetups

Looking for speakers to go deep on AWS?

Would your user group \ meetup appreciate hearing about .NET on AWS from an AWS .NET developer advocate? The team of longtime .NET developers would be thrilled to join your virtual user group to chat about the latest for .NET in the cloud.

Here’s a list of example topics:

  • Overview of .NET on AWS: AWS has over a decade supporting .NET on the cloud. We’ll provide an overview of all the support you might not know existed, such as free tools for Visual Studio, PowerShell, Azure DevOps, etc.
  • Building serverless with .NET: The future is now for serverless, and AWS is ensuring .NET is vibrant in that future. We’ll show you how anybody can get started and take advantage of the speed and ease of using serverless with .NET.
  • Infrastructure as .NET: Why learn JSON or YAML to build on the cloud if you can just use .NET? Learn how to model and provision cloud resources in .NET with the open source AWS Cloud Development Kit (CDK)
  • PowerShell on AWS: AWS supports PowerShell and makes it easy to manage your AWS resources in a PowerShell scripting environment. We’ll show you all the things you can easily do on AWS with PowerShell, including native support for serverless.
  • Something else? What are you interested in hear about? Blazor? ML? Reach out and let us know.

You can contact the .NET developer advocacy team at aws-dotnetfdn-interest-open@amazon.com. Cheers!

Dev Around The Sun organizers announce Quicken Loans as a Gold Sponsor for their conference May 12th. The virtual conference brings technologists together from all backgrounds; Dev Around The Sun — an online conference featuring a diverse group of technologists from all over the world. They will speak on a variety of topics, both high-level tech and human skills. Conference organizers created the event with two goals in mind: to raise awareness/provide financial support for the many people fighting the novel coronavirus pandemic, and deliver hope and reconnect the global developer community.

The event begins 12:00 UTC (5:00am PDT) May 12th, 2020. Speakers are scheduled to present for 24-hours. This global event aims to offer hope, raising awareness, and provide financial relief to people fighting the current global pandemic. Everyone is invited to attend for free. Tune-in to Twitch/YouTube. Sign up for updates at https://DevAroundTheSun.org.

"The two things that stuck out for me about this event were the mission; Part of our culture is 'doing the right thing' and anything we can do to contribute, I think there is value there," said Quicken Loans CIO, Brian Woodring. "Second, this is a great opportunity to engage our team and connect us to the global developer community. Especially at a time like this, when a lot of conferences are being canceled and training isn't available. A lot of the resources that people would normally use aren't available. I thought this would be a fantastic opportunity to give our team the chance to engage and rally."

Hear technologists from a broad set of communities, spanning many technologies and continents as they educate, entertain, and inspire our international audience in the comfort of their own homes. All proceeds go to Direct Relief's coronavirus fund. The fundraiser is hosted by the .NET Foundation.
