New Post: Is using this MVPVM pattern with Caliburn possible?

"MVP = MVVM they are almost completely synonymous with each other"

Actually, that statement could confuse the development community, I'd like to share some info....

The PresentationModel and MVVM are synonymous - John Gossman, founding father of MVVM, explains this in his “PresentationModel and WPF” blog entry at bit.ly/pFs6cV. Like Martin Fowler, he was careful not to overload terms. This effectively gives us a clear understanding of what MVVM is; it’s a “WPF-specific version of the PresentationModel pattern.”

The "Presentation model" exhibited exactly the problems that mugen_kanosei is discussing. Martin Fowler states the following on the topic:

"Directly updating the widgets like this is not part of Presentation Model, which is why the visual works application model isn't truly a Presentation Model. This need to manipulate the widgets directly was seen by many as a bit of dirty work-around and helped develop the Model-View-Presenter approach."

So MVP is the evolution of Presentation Model (aka MVVM).
