Deliver cross-platform business applications in a single sprint.

Support M-V-VM Development Pattern.

The key advantage of MVVM is the clear separation of the User Interface (View) from the business object and behaviors (ViewModel) and from the data layer (Model). Your code becomes easier to write, read, test, maintain and scale.

Support M-V-VM Development Pattern.

ClientUI includes a powerful yet high-performance library to facilitate a real-world M-V-VM pattern application development, including routed events, delegate command, command reference, navigation and dialog box service provider, and an easy-to-use binding library. This enables user interface designers and application developers to focus at what they are best, then quickly snap the two halves into a professional and compelling data-driven business application.

WPF-style Silverlight Development.

Despite being a subset of WPF, building a basic line-of-business Silverlight application could be a tedious task which requires a great deal of effort and codes due to the lack of essential application frameworks such as commanding and MVVM. Revolutionizing the Silverlight development, ClientUI introduces full-featured event routing and commanding framework. Combined with M-V-VM pattern, you can write the logic of a command in a separated layer and bind them through command binding in the view level. No events wiring, no codes rewrite, and no more redundancy.

Revolutionize the Speed of Development.

Accelerate the Speed of Development.

In addition to its innovative library, ClientUI also includes a new level of visual development experiences for your favorite IDEs, Visual Studio 2012 and Microsoft Expression Blend 4. Drag-drop a new instance, directly interact with a visual element, or quickly add items through context menu, the extended designer support lets you rapidly take advantage of ClientUI's innovative tools and deliver mega-sized project in realistic timeframe.
