Sharepoint Developer Notes

In Windows SharePoint Services 3.0, you could host a Microsoft Silverlight application in a Web Part. Microsoft SharePoint Foundation 2010 goes beyond by providing a built-in, extensible, Silverlight Web Part specifically designed to host Silverlight applications. Closely related to the new Web Part is the Fluid Application Model (FAM) that enables secure, cross-domain, integration between external applications and SharePoint Foundation deployments.
