Your reasoning is questionable and suspect to favoritism. Granted I understand practically nothing about MVVM, but when an architecture which include MVC can mimic the actions with-out being forced to write 50k lines of code, then whats the big offer?

Nicely thats accurate but not very helpful. The greater suitable definition of the VM is "Anything you must render your web page." When you examine right down to The underside I've recognized the elements you have to build your VM's properly and simply, in lots of instances leveraging your present domain models and presentation models.

(organization applications) Due to the fact a ViewModel is just a class, the easiest way to get view model in asp.net mvc started using one is to produce a new folder named ViewModels and increase a different code file to it.

When using [the "ViewModel"] pattern we create strongly-typed classes which are optimized for our particular view scenarios, and which expose Attributes for your dynamic values/content essential by our view templates.

Internet MVC make your software tightly coupled to DTO and that's just the alternative goal of working with DTO. If you do so, what's the real difference utilizing your area Model or DTO, a lot more complexity to receive an anti-sample ?

Given this scenario you'd only have this a person price/property within the view model and not all of the properties which are in the domain item.

Now they've tossded that out but hoisted yet again A further desktop model on this new paradigm for World-wide-web dev.

Are The only source of info used to render a web site or monitor. Commonly, Therefore a view model will expose each individual house that any Management about the webpage will need to render alone accurately.

 We're going to produce a strongly typed view by selecting the Model class ProjectViewModel and we wish to make a Record. The scaffold mechanism will generate our view that you could see down below. As you'll be able to see down below in the primary line of the view I pass the ProjectViewModel ViewModel.
