Recapping Xamarin Developer Summit

Maddy Montaquila

The first-ever Xamarin Developer Summit has come to a close. The Xamarin team had an action-packed two days of announcements, talks, and hanging out with our community in Houston! Here is a recap of some of the most important pieces you may have missed if you weren’t able to join in person or watch through the live streams. 

What is Xamarin Developer Summit?

Xamarin Developer Summit (#XamDevSummit) is a conference focused on Xamarin mobile app development. It was started, organized, and executed entirely by our amazing community. There were two days packed with sessions, workshops, and visiting product “lounges” – a new take on conference exhibition booths. Hundreds of Xamarin developers came together to discuss the latest and greatest features, tools, and strategies for Xamarin development.

Keynote Announcements

Xamarin Developer Summit started off strong with the Thursday morning keynote. Filled with announcements across our SDKs, tools, and more. First, James Montemagno covered everything we’re doing to keep up with our proud tradition of having 100% native functionality. Next, David Ortinau shared the innovations we’re working on to make it easy to create 100% cross-platform .NET mobile apps using Xamarin.Forms. Finally, I walked through improvements in our tooling to make you more productive while developing Xamarin apps. For day two’s keynote, Donovan Brown taught everyone how you can use Azure DevOps and App Center to prevent outages for your customers and make mobile app development better for your developers.

Mobile DevOps with Xamarin, App Center and Azure DevOps

Listening to Our Community 

Poker chips lined up near the lids of potential Xamarin.Forms features

The Xamarin team couldn’t resist getting feedback on our announcements, direction, and roadmap from all of the Xamarin Developer Summit attendees. Every attendee was given a Xamarin-themed poker chip and asked to vote for a potential future Xamarin.Forms feature. Once they voted, they filled out a survey in exchange for Xamarin swag. Nearly all of the attendees participated, and Faster App Startup is the winning feature!

Additionally, many Xamarin PMs, Cloud Developer Advocates, and engineers were at the conference. They took this opportunity to chat with community members, sharing advice, and giving talks of their own. 

Videos on Demand

Each day of the conference we hosted a full live stream of the Microsoft track at the conference that thousands of developers tuned in for. You can watch all talks by Microsoft employees on the Xamarin Developers YouTube Channel.

A great place to start is with the main keynote: A Glimpse Into the Future of Xamarin:

Thank You!
