If you are already enrolled in the UWP developer preview program and have activated Developer Mode on your Xbox One console, it will be automatically updated to the new build in the next day or so or you can start the update yourself by going to Settings | System | Console info & updates and clicking the button there. If the button is grayed out and says No update available, then you either are not currently in Developer Mode or you already have the June 2016 Developer Preview build installed. When the June 2016 Developer Preview build is installed, the OS version you will see in the Console info & updates page is 10.0.14352.1024 (rs1_xbox_rel_1606.160609-1700).
If you are not yet enrolled in the developer preview program, now is a great time to check it out. You can find more information about how to enroll on the Getting Started page.
