Blog Post: 70-511 Exam Guide: Threading Model, Dispatcher

 

Totally AWESOME sample: Threading Model

Do what it takes, memorize the DispatchPriority Enumerations (not the numeric component, just the Member names and how to use them):

• Invalid: This is an invalid priority.
• Inactive: Operations are not processed.
• SystemIdle: Operations are processed when the system is idle.
• ApplicationIdle: Operations are processed when the application is idle.
• ContextIdle: Operations are processed after background operations have completed.
• Background: Operations are processed after all other non-idle operations are completed.
• Input: Operations are processed at the same priority as input.
• Loaded: Operations are processed when layout and render has finished but just before items at input priority are serviced. Specifically this is used when raising the Loaded event.
• Render: Operations processed at the same priority as rendering.
• DataBind: Operations are processed at the same priority as data binding.
• Normal: Operations are processed at normal priority. This is the typical application priority.
• Send: Operations are processed before other asynchronous operations. This is the highest priority.
