I would like to share some of my basic understanding of Silverlight internals in this series.
XAP File
When you build a Silverlight 2.0 application, the final outcome would be:
ApplicationName.dll
AppManifest.xaml
ApplicationName.xap
When a request is made for a page which contains a Silverlight, the server sends the page with the Silverlight part as “xap” file to the client. The XAP is a normal archive file you use archive manager like 7-Zip to extract the content. It contains RequestSilverlightApp.dll and AppManifest.xaml. The silverlight CLR at the client side consumes these. This should be specified in either ASPX or HTML file which is the actual client requested page.
You use OBJECT tag along with DIV and IFRAME to load Silverlight host and specify the target XAP needs to be loaded.
