MediatR topics
12 short topics in Event-Driven and Asynchronous Systems. Each one is a single focused exercise with a clear piece of evidence at the end.
12 topics, one exercise each.
Work through them in order, or jump to the one you need.
These are draft topic outlines (draft; instructor review pending). Full lessons follow after review; ask Ajay if you need a topic sooner.

Command and query contracts
Demonstrate command and query contracts in a focused MediatR example; verify normal behavior and one edge or failure case. Keep the exercise bounded and record the behavior supported by the chosen version.
Open micro-course → - 02
Handler registration
Demonstrate handler registration in a focused MediatR example; verify normal behavior and one edge or failure case. Keep the exercise bounded and record the behavior supported by the chosen version.
Open micro-course → - 03
Dispatch and routing behavior
Demonstrate dispatch and routing behavior in a focused MediatR example; verify normal behavior and one edge or failure case. Keep the exercise bounded and record the behavior supported by the chosen version.
