Visual Studio: Creating several projects in ONE solution?

consider a mvvm/wpf applicatio开发者_Go百科n, what advantage has it to do for example 3 projects (View, ViewModel, Model) in a visual studio solution?

I can't think of any real advantage to splitting your view, viewmodel and model into separate projects, unless they are large and you need better organization or you would like to compile them to dlls that can be versioned independently.
