Take the 2-minute tour ×  I;m trying to get WCF Silverlight
faults working as per this : MSDN aricle  After adding the SL
fault to my Web.config file I get the following warning:  The
element 'behavior' has invalid child element
'silverlightFaults'. List of possible elements expected:
'serviceAuthorization, serviceCredentials, serviceMetadata,
serviceSecurityAudit, serviceThrottling, dataContractSerializer,
serviceDebug, serviceTimeouts, persistenceProvider,
workflowRuntime'.  Ignoring the warning doesn't work and my
Silverlight application cannot add the WCF service.  Any ideas?
share|improve this question You should post the relevant part of
your web.config, without it all anybody can do is guess what
your problem is. –  slugster Jun 7 '10 at 2:43  3 Answers 3
When you add the behavior extension, the type specification must
be on a single line. No CRLF allowed in that section.      <add
name="silverlightFaults" type="SilverlightFaultBehavior,
Utilities, Version=, Culture=neutral, PublicKeyToken=null" /> s
