I have a silverlight app using RIA services. I want to reuse the RIA services component and call it from another web service. The web service and the RIA services component will be on the same server.
I have got quite far along, my web service project has a 'service reference' to the RIA services project which is all good. But when I call one of the RIA services methods I get the exception,
{DDB20766-F78A-42c7-B777-5ECF0AD9E4F3}Access to operation 'GetValidId' was denied.
at System.ServiceModel.DomainServices.Server.DomainService.ValidateMethodPermissions(DomainOperationEntry domainOperationEntry, Object entity)
The RIA services domain class has the attribute [RequiresAuthentication]. I am trying to understand how I can specify those credentials and authenticate?
Just as a test I commented out the attribute [RequiresAuthentication] and everything worked without any problems.
