What is the best way to instantiate a view and the corresponding view model in WPF application within the MVVM pattern? In other words, when an application launches maybe there is an main view that is launched and the corresponding view model is somehow created. On the main view, the user is able to click on a button that has the command property bound to an ICommand object in MainViewModel. The purpose of the button is show data on a different view. So what is the best way for the new view and corresponding view model to be instantiate and the view to Show? Without the MainViewModel doing the work. With MVVMLight, it there a standard technique that is commonly use?

Thanks

Thanks. I have already read link 1. It is very good. But I don't think it really addresses my question. I think the article only shows a MessageBox from the main view model. Doesn't even involve another view model. I am talking about another view and view model. Where and how would they get create? Outside of the view model. I suspect the answer going to involve a messaging service. Thanks
