First a big thank you, I'm a relative newcomer to both Silverlight and MVVM, the Simple MVVM toolkit is the first one I have tried that has made sense to me! I now have my first MVVM application up and running, lovely stuff!
I now want to move on and try something a little different. Rather than have a VM that maps directly to a table containing a large list of entities and filtering it to return subsets, I want to sum a bunch of custom totals/averages etc
with custom code on the server so the client can retreive a single read only entity via WCF RIA that does not directly map to any specific table. This would then feed into my "dashboard" View model.
I have found lots of posts on different sites referring to DTO's, POCO, etc which just succeeded in confusing me. The clearest explanation I have found so far is by
Jeff Handley on "DomainDataSource – Single Record Results".
I am having real difficulty working out how I would integrate this with MVVM and the rest of the toolkit. Can anyone suggest any good blog post/resources that could help me out with my my current lack of knowledge?
