Silverlight MVVM - Where does the asynchronous service logic go?

Question

I have the beginning of my first Silverlight MVVM application and need to know where I should put the business logic, including asynchronous service calls. This happens on the page, where is the presentation? Am I just setting the ViewModel property that updates the view?

Answer 1

Running MVVM in Silverlight is more complicated than in WPF, but we did. Yes, we are calling the asynchronous call service in the ViewModel. The “model” in our case is proxy objects that are sent back and forth upon a web service call. Unfortunately, this means that some of your functions are located in your ViewModel client, and some are server-side. There is no way around this.

Answer 4

I put my calls to asynchronous services in the model and connected to events from my view model that fire when the data returns to the model.
