Blazor.EventAggregator now works with Blazor 0.9. The library was first released back in February when Blazor was still (partly) called Razor Components and we were still using .cshtml-files. Blazor.EventAggegator 1.1.0 release updates the library to work with latest preview bits of Blazor.

For those not familiar with Blazor.EventAggregator, it is a lightweight Event Aggregator for Blazor. Event aggregator is used for indirect component to component communication. In event aggregator pattern you have message/event publishers and subscribers. In the case of Blazor, component can publish its events and other component(s) can react to those events.
