Yes, you can inject the
Region Manager in your views/presenters and use it to load a view into a region. Moreover, a good practice could be to have a
Controller class that handles the loading of views, as the controllers are usually used to coordinate the activity of multiple views.
The UI Composition QuickStart shows a sample implementation of a typical controller class in the
UIComposition.Modules.Employee\Controllers\EmployeesController.cs file (this controller coordinates the interaction of the Employees module's views).
If you need more information about controllers you can review the
Employees Controller section of the UI Composition QuickStart article.
Please let me know if this helps.
