MVVM, also known as the Model-View-ViewModel architecture pattern, was first introduced by John Gossman for use with WPF. It was implemented with the intention of separating the controls of the application user interface from their logic.
Implementing an application based on the MVVM pattern requires the use of certain capabilities (commands, data binding, and behavior) of XAML application platforms such as Silverlight and Windows Phone. Similar to other architecture patterns, such as MVC, MVVM separates the issues of appearance, i.e. the user interface and the program logic.
Many people prefer to implement the MVVM architecture for Windows Mobile application development, and the reasons are:
- MVVM provides separation of concerns. It allows you to separate the logic and interface of the application, which makes it easier to test, develop and maintain the application. So,
a) It supports a modular architecture that allows components to be built and tested independently.
b) It offers the advantage of loose coupling, which makes it easy to make changes to one part of the program without affecting another or requiring another to change.
c) It makes it much easier to maintain the application during updates because of the ease of implementing changes due to a well-structured design.
d) It makes the application less error-prone because separation allows for development with less coding, which means less code means less errors.
e) It allows you to automate unit testing of the code, so no UI-based testing is required.
Do you have any questions? Why don’t you write to us?
- It provides an easy workflow between designer and developer. Here, the user interface is loosely coupled with the code and hence it gives the designer full freedom to realize his creativity to offset a good product.
- Improves program testing. Testing the user interface becomes easier with MVVM because here the UI logic can be easily moved to a separate class, an instance of which can be created independently of the UI technology.
- MVVM is a natural template for XAML platforms and therefore allows you to use the data binding stack and dependency properties for the application. So, now the user interface can easily connect to the view model as a result of their combination.
Where can I build MVVM-based Windows Phone apps?
Developing Windows Phone applications based on the MVVM pattern requires the use of Visual Studio. Applications will consist of three layers called Model, View, and ViewModel with dependencies.
To develop a Windows Phone application using MVVM, you need to do the following
First, choose File->New Project in Visual Studio. Here, you can either create the application code from scratch or select “Silverlight for Windows Phone” from the “Installed Templates” list to develop a Windows Phone application.
