.NET Conf 2019

.NET Conf 2019 is a wrap and it was the largest one yet all because of you and our wonderful community. THANK YOU! We had over 100,000 views, 77 live sessions, gave away $20,000 worth of prizes and best of all, .NET Core 3.0 is released! What a week.

Sessions are now available on demand so be sure to check out anything you missed. We're still processing and uploading some of the Day 3 sessions but most of them are ready. Some of the more popular sessions were the Keynote, C# 8.0, and Blazor. The decks and demos are up on GitHub for you to use in your presentations and Meetups.

Watch sessions on-demand on YouTube.

We could not have pulled this event off without you. Please take a moment and provide feedback on this anonymous survey. This will help us improve for next year. 

Tell us what you think.

Finally, join the conversation still happening at #dotNETConf on Twitter, view all the amazing photos, and show off your love for .NET.

From the Polly community this month:

Orleans 3.0

Orleans is a cross-platform framework for building distributed applications with .NET

Some of the headline changes since 2.0 are:

  • Distributed ACID transactions — multiple grains can join a transaction regardless of where their state is stored
  • A new scheduler, which alone increased performance by over 30% in some cases
  • A new code generator based on Roslyn code analysis
  • Rewritten cluster membership for improved recovery speed
  • Co-hosting support via .NET Generic Host
  • New networking layer with support for TLS, based on ASP.NET Bedrock
  • Improved reliability and extensibility
  • Many other improvements and fixes

DotVVM is looking for Developer Advocates

Do you want to help an open-source project to grow and find more users? DotVVM is looking for Developer Advocates - a group of individuals that could help us with publishing articles and blog posts, speaking about DotVVM at conferences or community events, recording videos or doing any other activity that would contribute to sharing the DotVVM story to the broader community of .NET developers.
