Hi All,
I am facing an issue with consuming WCF service from a Silverlight web part hosted in a SharePoint 2010 page.
The Silverlight Web part is deployed in to a SharePoint 2010 site. Silverlight component is getting the data from a WCF service which is deployed in a different web application on the same server as used by Sharepoint 2010. Both SharePoint site and WCF services are configured with Windows Authentication.
Issue: During the WCF service call (happens for the first call only) from the Silverlight web part the browser prompts the user for credentials.
The client machine and the Sharepoint Server are in the same domain. Actually it should take user credentials from the browser or from SharePoint page.
I have followed the MSDN article: http://msdn.microsoft.com/en-us/library/ff648505.aspx and also checked the IE settings to allow the credentials to flow from browser to the WCF service. (http://msdn.microsoft.com/en-us/library/dd744835(v=vs.95).aspx)
Expected behavior is that it should not prompt the user for the credentials.
