XAML has become overlooked as a solution for creating application user interfaces. But, while new technologies have emerged, XAML is still an excellent choice for creating a UI. It's great for creating the front-end for Windows, Mobile, and Web software in a declarative, easy to read, and a composable way. This talk covers recent updates to the tooling and functionality from Microsoft, 3rd parties, and the OSS community. It also looks at techniques, patterns, and practices to enable you to create XAML you can easily visualize and maintain. This talk is the result of more than ten years of experience with XAML and recent work to improve XAML tooling and capabilities within both Microsoft and the Open-Source community.
