7. Mango Improvements
1. General Runtime Improvements
Examples:
Faster, more responsive scrolling
Lower memory footprint
Better video playback
2. Improved Default Behaviors For 7.1 Apps
Examples:
Fast-App-Switching
Better XAML Parser
3. New Optional Behaviors For 7.1 Apps
8. 32 Bits-Per-Pixel Rendering
7.0 supports only 16 bpp rendering
banding in gradients
In Mango the default is still 16 bpp
Apps can opt-into 32 bpp in the manifest
Recommended if your app wants to show
Photos
Designs with gradients
Video apps get opt’ed in automatically
12. Media and Objects

14. Memory Testing
First: Design your app with memory in mind
Monitor your memory usage
Test with real word data
Consider monitoring your “heavy” objects
Page instances
UserControl instances
Data objects that participate in binding
Tiny UI leak can cause entire visual tree to be
leaked
Use the 7.1 Profiling Tools
16. Control Your App With Sockets
Use socket APIs to connect to your desktop
computer
This can be useful for testing/debugging
scenarios:
Monitoring app metrics (such as memory/heap
objects)
Logging messages/results
Controlling the app workflow
17. End-To-End Testing
Navigating through the entire app
State and visuals are correct
No leaks and no crashes
Investing in an automated script may pay off
Do the math
Consider your test matrix
Think about stability (memory and stress testing)
Write code with testing in mind
19. Windows Phone Marketplace
Test Kit
Objectives : Protect to fail submission process
