A managed code application using ImageGear for Silverlight should be created as a web Silverlight application, i.e., using "Add a new Web to the solution for hosting the control" host method (NOT "Generate an HTML test page to host Silverlight within this project") and targeted for any CPU .NET platform, so it can be run from the HTTP protocol under the browsers and operating systems supported by Microsoft Silverlight.
The ImageGear for Silverlight application can be distributed as a XAP file, which is directly generated from Microsoft Visual Studio. This distribution will automatically include all the ImageGear for Silverlight assemblies referenced in the application.
