Comment Feed for Channel 9 - OData Roadmap: Exposing Any Data Source as an OData service http://files.ch9.ms/mix/2011/thumbs/FRM16.jpg Channel 9 - OData Roadmap: Exposing Any Data Source as an OData service Many of the popular OData services, including Netflix, Twitpic and Facebook Insights were built by reusing their existing web API with an OData service. Implementing this type of OData service is not simple but it’s also not as hard as you might think. In this session, you’ll learn how to build similar services that wrap different types of data sources using the WCF Data Services Toolkit. We’ll take a look at the implementations for several of the popular services as examples of how to use the toolkit to create new OData services. en Wed, 19 Jun 2013 17:21:32 GMT Wed, 19 Jun 2013 17:21:32 GMT Rev9 Re: OData Roadmap: Exposing Any Data Source as an OData service posted by Rasmus Christensen

Sorry to hear you're having some issues. First off: the toolkit assemblies that are publically available are built against .NET 4. They can be used with the new CTP (as I did at MIX), but you'd have to download the source from Codeplex and rebuild them against those assemblies. I didn't actually use any OData v3 features in the session, so my use of the CTP was pretty superflous.

The 500 error you're getting is a generic WCF error and could be from anything, and it's vague nature isn't because of the toolkit, that's a behavior of WCF. If you add the following attribute to your service, you should see a better error message:

[ServiceBehavior(IncludeExceptionDetailInFaults=true)]

Feel free to ping me if you continue having issues.

I'm hugh WCF newby!! I was really excited by you presentation and wanted to try this out.

The problem was in the step where you set [DataServiceKey("Id")]. You were saying you like to override with a lower case id. I unfortunately typed "id".

Your ServiceBehavior yielded a message that pointed to the problem!!

Thanks!!

Paging doesn't work like it does in the video (my ODataQueryOperation SkipCount and TopCount are always 0) and if I get source from the codeplex and use that assembly I don't get v3. Interesting. Perhaps a link to a working demo project? That would be excellent!

Did you set a page size for the entity set you want to page? Without doing that, SkipCount and TopCount won't be enabled. It's a bug that needs to be fixed.

As far as the v3 part, that is because I was using the CTP version of WCF Data Services in the demo, while the toolkit code on Codeplex isn't.
