If there are any illegal characters or badly formed XML within the service structure, this will cause the HubClient to throw and error and result in service views not displaying in the BSD. If service views are not loading, check the .NET console. If the problem lies with the XML, you will see errors similar to below:
00000249 36.61344910  ERROR: ViewLoader.OnUnhandledException : Error: Unhandled AppDomain exception caught. CLR forcing termination: True Exception: System.Xml.XmlException: An error occurred while parsing EntityName. Line 1, position 50.
To resolve this, remove any reserved XML characters from the service structure : Names, Labels etc.
