Recently, I was introduced to Infragistics' NetAdvantage for Visual Studio LightSwitch. I was very impressed with the product, and in this review I intend to show you what impressed me about it... LightSwitch provides a designer that you use to design your client screens; the designer includes a sparse collection of Silverlight controls for use on the design surface. The design process is analogous to binding user interface (UI) widgets to data sources. However, the fundamental difference is that a LightSwitch UI screen represents an independent unit of work on the client. And because of that, each screen has an isolated state from other screens. NetAdvantage for Visual Studio LightSwitch ties right into the designer experience, so that the mechanics of the design process are the same as that of Visual Studio.
