Decoupling Complex Workflow In WinForms For Iterative Development And Incremental Delivery

One of the most significant challenges of working within a release-per-feature project lifecycle is managing features as independent parts of the development cycle. At some point, the various features will need to be integrated into the trunk or master source code branch. When this occurs we want the different features to integrate as smoothly as possible. To accomplish this we look to design and implementation patterns that provide reduced coupling between our features while still providing the ability for them to communicate and work together. In this presentation we will walk through the use of an Application Controller, Event Aggregator and Command Pattern in combination with a good IoC Container, to show how we can reduce the coupling between forms in desktop systems. These patterns, among others, will help us to develop interconnected software modules that can be developed and managed independently.
