Sometimes the Prism Application may need the hierarchical event aggregator. In this post, I want to share my implementation of HierarchicEventAggregator.

IHierarchicEventAggregator.cs
HierarchicEventAggregator.cs

1. To create the instances, do the following:
IHierarchicEventAggregator root = new HierarchicEventAggregator();
IHierarchicEventAggregator workspace1 = root.CreateChildHierarchicEventAggregator();
IHierarchicEventAggregator workspace2 = root.CreateChildHierarchicEventAggregator();
