PRISM: Composite Application Guidance for WPF and Silverlight

Also he talked about frameworks created to help assist in rapid development using these patterns without sacrificing good application development patterns. MVVM is a pattern, there is no specific way to do it right.

People look for patterns to describe common way for programming The interesting part of this application is that views can be imported into the main window as dynamic parts, simply by decorating them with the MEF Export attribute. In the first post of this series I generally wrote about Prism and how can it fit in WPF applications.

In this second post I would like to introduce a Home Automation application UI, show how to design it as a monolithic application, talk about the disadvantages of a monolithic application, and finally show how to design it as a Composite Application.

What is a Home Automation? For others, security may be the central application. Still others may choose to install We should know how to control both. I will start with WPF has a great support for handling data: Unfortunately, one of the elements you bind to the target must have a DependencyProperty known as the target-property.

Before I will start, I want to give a little background of the WPF threading model, and to explain why you shouldn’t change any data-bind object from a different thread. The WPF threading model is very simple: This means that like other UI technologies such as Windows Forms, WPF extends this mechanism by adding some great features, especially when dealing with Data Templates, which provides an easy way for reflecting the data with view.

Data binding is a great mechanism, but there are some situations that data-binding not exactly fits. As every aspect in the real life especially in softwarenot everything is perfect and so is WPF.
