Using the Message Mediator Service in MVVM Helpers - by Mark Smith (@marksm)
One of the services exposed in the MVVM Helpers library is a Message Mediator. This service implements the mediator design pattern which is used to enable objects to talk to each other without having any explicit knowledge of each other. In this pattern, we use a third-party object (the “mediator”) to negotiate communication between the interested parties.
The message mediator is actually part of the JulMar.Core assembly – this is a general .NET assembly that contains useful code, extensions and services which are not specific to the presentation technology being used (i.e. they can be used in any .NET project type). I actually work in all kinds of fields and technologies, but WPF has a special place in my heart – and it turns out this service is pretty useful for GUI applications to enable loose-coupling between elements, particularly when you are relying on other design patterns such as Model-View-ViewModel (MVVM).
