WCF Data Services 5.1.0-rc Prerelease

Less than two weeks ago, we released WCF Data Services 5.0.0. Today, we are releasing 5.1.0-rc as a NuGet prerelease.

What is in the prerelease

This prerelease contains several bug fixes:

• WCF Data Services fails to work properly with the $expand query option when using the DevArt Oracle EF provider
• Some DateTime values do not round-trip properly in JSON verbose
• Incorrect metadata version calculation on a V3 service with both service operations and actions

Getting the prerelease

The prerelease is only available on NuGet and must be installed using the prerelease cmdlet. Prereleases are not displayed in the Manage NuGet Packages dialog. To install this prerelease NuGet package, you can use one of the following commands in the Package Manager Console:

• Install-Package <PackageId> –Pre
• Update-Package <PackageId> –Pre

Our NuGet package ids are:

• Microsoft.Data.Services.Client (WCF Data Services Client)
• Microsoft.Data.Services (WCF Data Services Server)
• Microsoft.Data.OData (ODataLib)
• Microsoft.Data.Edm (EdmLib)
• System.Spatial (System.Spatial)

Call to action

If you have experienced one of the bugs mentioned above, we encourage you to try out the prerelease bits in a preproduction environment. As always, we’d love to hear any feedback you have!

  @Rod - thanks for trying the RC! Could you open an issue on the forum so we can have more of a discussion? (social.msdn.microsoft.com/.../threads) Also, would be very helpful to have a trace of the problem from Fiddler.
