Showing Sharepoint data in silverlight using Sharepoint web services.

Reference:

http://channel9.msdn.com/posts/kirke/SharePoint-for-Developers-Part-4-Calling-SharePoint-Web-Services-from-Silverlight/

1) Create a silverlight application.

Add a reference to your SharePoint web service. Select Project, Add Service Reference…

In the Add Web Reference dialog box, enter the URL of the ‘Lists’ web service. Web services in SharePoint are located in the ‘_vti_bin’ directory under the relevant site. If you are using web services to access your My Site, then enter the URL: ‘http://my/sites/your-alias- here/_vti_bin/lists.asmx’. If you are using web services to access a SharePoint site located at http://ourteamsite, the URL will be ‘http://ourteamsite/_vti_bin/lists.asmx’.

Click the Go button to confirm the URL. If you have entered a valid URL, then this dialog box tells you that it found a web service. The dialog box will be populated with the various operations available in the web service.

Change the web reference name to something relevant. For accessing the Lists web service, a good web reference name is ‘ListsWebService’.
