Here's a minimal checklist to make sure your OData Service is available to a maximum number of clients and very functional out of the box . I'll add more items to this list as we go along. Allow Silverlight clients to access your data. Silverlight applications running on a domain other than the one the Data Service is hosted on require a ClientAccessPolicy.xml file at the root of the webserver. Without a CAP.xml file , an in-browser Silverlight application cannot...

While developing an application that spans multiple tiers , it is important that you be able to flow error information through the tiers without losing any context or details in the tiers.
