CPS requires strict adherence to the rules and guidelines at Threading Rules
Important:
Do not call Task.Wait() or Task.Result in your code because these violate threading rule #2 and will often lead to deadlocks.
Avoid use of ThreadHelper.JoinableTaskFactory as that does not have the intelligence
to mitigate deadlocks between the UI thread and the CPS project lock. Instead,
use a CPS-specific JoinableTaskFactory instance, such as the one found on
IProjectThreadingService.JoinableTaskFactory
Alternately if you want to create your own JoinableTaskFactory instance (for
example to associate with your own JoinableTaskCollection) you can call IProjectThreadingService.JoinableTaskContext.CreateFactory(joinableTaskCollection).
