In my example, I have given some meaningful name like "SP2010Silverlight_HelloWorld" and create the project. To get started, create a new Visual Studio project titled Contoso.SharePoint.WebParts, and leave the project as a Sandboxed Solution when prompted. DLL's Needed: Microsoft.SharePoint.Client.Silverlight.dll and Microsoft.SharePoint.Client.Silverlight.Runtime.dll.

The client object model brings the richness of the SharePoint API to client side development using either the full .NET framework, Silverlight, or jQuery. Why does Deep Space Nine spin?

If not, why not? Build the project, upload the new XAP file into the doc library (override old one), and test your web part. The issue is fixed. We want our story board to start when the user clicks on the text block.

Keep in mind that anonymous users will then have access to content stored in the site if they know how to access them, so you may want to use distinct anonymous http://community.bamboosolutions.com/blogs/sharepoint-mvp-blogs/archive/2010/04/06/fix-unhandled-error-in-silverlight-2-application-invalid-cross-thread-access-error.aspx Lastly, change the Deployment Type to be ElementFile: Credit: I first saw this tip on Andrew Connell's blog.After you click OK, your module will have a new File in its XML.

Can you please suggest any sites which were developed using above mentioned tools? You don’t have to do client side development with SharePoint, but there are many advantages to doing so.
