Redefining Perspectives 4 - Metro ui Session 1
0 likes358 views
The document discusses the changing application paradigm with the introduction of Windows 8 and the Metro UI. It covers how applications need to change from monolithic desktop applications to smaller focused applications for different devices. Developers need to create modular applications that can be reused and activated from other applications to support multiple devices through standards-based contracts and charms. The key changes discussed are developing smaller focused applications, exposing activation contracts, following standards, and managing application lifecycles for different devices and form factors.
