With the latest generation of .NET technologies such as Silverlight 4 and WCF RIA Service, the development of RIA applications is easier than ever. This practically focused presentation aims to show, how to use these tools and other .NET technologies to develop high quality RIA applications. Moreover, we will also show, how to effectively use automatic code generating using Text Template Transformation Toolkit (T4) to extremelly reduce the time needed for their development.
