WCF Data Service 5.0.2 Released

We’re happy to announce the release of WCF Data Services 5.0.2.

What’s in this release

This release contains a number of bug fixes:

  • Fixes NuGet packages to have explicit version dependencies
  • Fixes a bug where WCF Data Services client did not send the correct DataServiceVersion header when following a nextlink
  • Fixes a bug where projections involving more than eight columns would fail if the EF Oracle provider was being used
  • Fixes a bug where a DateTimeOffset could not be materialized from a v2 JSON Verbose value
  • Fixes a bug where the message quotas set in the client and server were not being propagated to ODataLib
  • Fixes a bug where WCF Data Services client binaries did not work correctly on Silverlight hosted in Chrome
  • Allows "True" and "False" to be recognized Boolean values in ATOM (note that this is more relaxed than the OData spec, but there were known cases where servers were serializing "True" and "False")
  • Fixes a bug where nullable action parameters were still required to be in the payload
  • Fixes a bug where EdmLib would fail validation for attribute names that are not SimpleIdentifiers
  • Fixes a bug where the FeedAtomMetadata annotation wasn't being attached to the feed even when EnableAtomMetadataReading was set to true
  • Fixes a race condition in the WCF Data Services server bits when using reflection to get property values
  • Fixes an error message that wasn't getting localized correctly

    WCF Data services supoort Oracle DB?

  2. @alduar – WCF Data Services is to some extent backend-agnostic, meaning that it needs to be bound to a data store somehow. WCF Data Services does play very nicely with Entity Framework, and there is an Oracle provider for Entity Framework, so I would imagine you could build a nice OData stack on top of Oracle fairly easily. I have not tried it myself.

    Very happy to see support for DateTimeOffset.   🙂

    Is there anyway for this to be consumed by a Windows Phone app?  Currently I receive a "Can't cast to unsupported type 'DateTimeOffset'" exception when I attempt to update the entity.



  4. Hi Ant,

    DateTimeOffset is supported on the phone.

    If you can post your question on the forums (

    social.msdn.microsoft.com/…/threads ) ,

    I'd be glad to help you get this resolved or debug further.
