It's time for the April Update, subtitled The Calm Before The Storm edition... it's a relatively quiet month, but stay tuned for May when we'll have lots of news including several new projects joining and updates from the Build 2018 conference.

Speaking of Build... the .NET Foundation will have a .NET Open Source booth at Build. Come say hi!

.NET Presentations: Events In A Box!

Need a presentation or workshop content for your event? We've got you covered! We've launched an Events In A Box mini-site, with links to repositories full of decks, demos, and workshop scripts. These are open source repos on GitHub, so you can use, remix, share, and contribute to them. We'll continue to add to and build out the content, and look forward to your feedback and contributions.

.NET Foundation Project News

Polly Integration with ASP.NET Core 2.1

We are excited to announce that starting with ASP.NET Core 2.1, Polly integrates with the new IHttpClientFactory. The HttpClient factory provides a central location where you can create and manage HttpClient objects, simplifying and enhancing how you use HttpClient in the four following ways.


  • allows you to name and configure logical HttpClients. For instance, you may configure a client that is pre-configured to access the GitHub API;
  • manages the lifetime of HttpClientMessageHandlers to avoid some of the pitfalls associated with managing HttpClient yourself, such as socket exhaustion;
  • provides configurable logging (via ILogger) for all requests and responses performed by clients created with the factory;
  • provides a simple API for adding middleware to outgoing calls, be that for logging, authorization, service discovery, or resilience with Polly.

The Polly team has worked with the Microsoft ASP.NET Core team to release a new extension NuGet package, named Microsoft.Extensions.Http.Polly. This extension helps you easily apply Polly policies to every outgoing call from an HttpClient instance.
