Harini Kannan on React Native - Episode 129

Joining Jeffrey today is Harini Kannan! Harini is a Program Manager in the Windows Developer Experiences and Platform team — a fast-moving and exciting team at Microsoft! Her team's charter influences a lot of different technologies from WinUI to XAML to WPF to React Native for Windows, and more! Their team connects everything around enabling the Windows native UI stack to be the best, most powerful, and the most modern technology that people can target to build really solid apps for Windows. They're always jumping on the latest technology and trying to give people the latest stuff with the best quality!   Over the last two years, the team has been building an incredible, one-of-a-kind collaboration across many other teams within Microsoft, with the goal of bringing React Native to Windows.   In their conversation together, Jeffrey and Harini dive into everything that her team does regarding React Native (as well as lots of other topics when it comes to rich and stateful native applications!) She shares how to build, deploy, and operate with React Native for Windows, the team's journey of adapting React Native to work on Windows, and shares her recommendations on getting started.   Topics of Discussion: [:38] Be sure to visit AzureDevOps.Show for past episodes and show notes.
