Hi Model-View-ViewModel (MVVM) is a design pattern which can be use in WPF and Silverlight. Model : Entities (Most of the time directly connect with the application backend.) View : Your silverlight screens. ViewModel : The glue between the Model and View. In Silverlight View and ViewModel will located in the client side and Model will located in server side.So We have to use Communication method to communicate between the Client and server side. Most of the time we user WCF Service for this. Why we use MVVM? 1. MVVM provide application to code reuse. 2. Simplifies the application. 3. Easy to maintenance and provide maximum support for the testing. It is good article in c-sharpcorner about the Silverlight MVVM. http://www.c-sharpcorner.com/uploadfile/econsultancy/silverlight-4-0-and-mvvm-pattern/ You can also see following link for Silverlight MVVM with WCF. http://www.codeproject.com/Articles/405415/Silverlight-Application-with-MVVM-WCF-and-EF WCF : Windows Communication Foundation (WCF) is a framework for building service-oriented applications. Using WCF you can send data as asynchronous messages from one service endpoint to another. A service endpoint can be part of a continuously available service hosted by IIS or it can be a service hosted in an application. An endpoint can be a client of a service that requests data from a service endpoint. The messages can be as simple as a single character or word sent as XML or as complex as a stream of binary data.
