I'm fairly new to MVVM and can follow it, but have problems tackling problems that stray from the books and tutorials I've read.Is there a source that covers more involved apps?
Where I'm stuck is intra-ViewModel communication. Let's say you've got an app with an ApplicationVM which drives a "center workspace" ViewModel that switches between content based on what needs to be accomplished. The "center workspace" will have one or more UserControls. (see pics) How should they talk to each other?
Thank You!!!
