This is a quick video of page-based navigation written in TinyCLR. This creates a top navigation bar with a home button and context-sensitive forward and back buttons and breadcrumb text, and a bottom status bar. Page navigation occurs in the center. The system maintains a forward and back stack and would feel comfortable to anyone used to iOS, Android, or UWP programming. The API resembles the UWP API.
BTW, I put this in Insiders because it shows the UD700 and in case it shows unreleased TinyCLR functionality.
