The Eclipse tools for Silverlight project, aka eclipse4SL, is an eclipse plug-in that enables Eclipse developers to use the Eclipse IDE to create applications that run on the Microsoft Silverlight runtime platform. The interoperability scenarios this project enables are very interesting, as it provides more choices to Java/Eclipse developers and opens up new opportunities for Silverlight adoption. This demo gives an overview of the developer experience of creating a basic Silverlight application in Eclipse, shows how collaborating with a designer could work, and gives a sample Silverlight application talking to a Java web service.
