DESCRIPTION
The client (or presentation) tier of our applications is taking on an increasingly important role. Users are expecting more compelling user interfaces, but they also want more functionality from their applications. In this ArcReady we examine how to design and deliver well architected client applications that will be easy to maintain and extend. Session 1: Trends and patterns on the client tier In our first session we will take a vendor and platform neutral look at some of the trends and emerging technologies that can be used on the client tier. We will look at techniques like Mashups, technologies like Natural User Interfaces (NUI) and the increasing importance of the mobile platform. We will also look at some common patterns that can be used in the architecture of the client tier. Session 2: Applying Microsoft technology on the client tier In our second session we will take some look at how we can use Microsoft technologies to create well architected and compelling client applications. We will look at technologies like Silverlight and WPF that can be used to create compelling clients. We will also look at technologies that can be used to make your applications more extensible for future development. We will also examine some architectural guidance developed by the Microsoft Patterns and Practices group.

WPF Vision• Unified approach to UI, Documents,
and Media– Integration as part of development
and experience
• Integrated, vector-based composition engine– Utilizing the power of the PC
throughout the graphics stack
• Declarative programming– Bringing designers directly into
application development
• Ease of deployment– Allowing administrators to deploy and
manage applications securely
