Q&A #18 – What are main threads that Silverlight for Windows Phone supports?
The Silverlight for Windows Phone supports 2 main threads
1. UI Thread
2. Composition Thread
The UI Thread handles the user input, parsing, event handling etc.
The composition thread helps the UI thread in animation (storyboards) and graphics and making the UI more responsive. The third kind of Thread is the Background threads.
