This is a sample that shows the use of Stateless and MediatR to model mobile applications' foregrounding, background, background launch, connecting, and disconnecting.
The goal of this sample is to solve the following requirements
- Provide a State Machine that models the application state
- Allow the State Machine to produce state information for downstream subscribers
- The solution should allow certain routines to execute during certain state transitions
- The routines should execute before the notification is sent to the downstream subscribers
- Keep the concerns as clear and separate as possible.
-
Mediator Design Pattern
- Isolate routines in Handlers
- Ensure the correct handler executes for the given event
- Allows a set of routines to execute based on the message received
-
State Design Pattern
- Encapsulate Application State
- Encapsulate handling of changes to Application State
- Allow observers to see changes in state over time
