Re: composing multiple bounded contexts in a single user interface

You are talking about creating a Composite UI. By Definition, such a UI
does not belong to a single BC. Depending on the UI-technology you use, you
can create UI-widgets that are responsible for rendering/displaying data
and communcate with the back-end systems inside a single BC. Then build a
Composite UI that aggregates those components into a single UI displayed to
the end user.

For example, for web/MVC you can think of separate MVC-services for each
BC, and one Compositie project that integrates those services. For WPF, you
can think of Modules/UserControls packed for a single BC, and integrating
them into a Master project.
