Missing includedresults for soap/msbin1 from WPF Client

[springyboy]

Hi everyone.

We're in the process of porting a large Silverlight application to WPF. We've done a spike that implements a WPF client that consumes data from one of the existing domain services updated to use OpenRiaServices.

We're using OpenRiaServices 4.6.3 and EF 4 via OpenRiaServices.EntityFramework.EF4 as we have a large number of EDMX models.

The spike builds and runs, but the domain service results do not include related entities (via the include attribute). If we point the test WPF client at the original endpoint (just change a config value, no rebuild, etc) then the same results return with related entities. What's missing from the OpenRiaServices results via the SOAP/msbin1 response are the IncludedResults section that the original domain service has.

Fiddler shows that the request is the same (it would be it's the same client), just the response that varies from WCF Ria Services and OpenRiaServices (two separate endpoints/projects).

What am I missing? Any help gratefully appreciated.

I do not know of any specific issue which would make the IncludeResults to be missing.

Some suggestions about what to try

1. Have you tried the normal "binary" endpoint or are you just using the "soap" endpoint ?
   While the soap endpoint should work it is not as well tested as the binary, which is known to work.
2. Do your project still reference "WCF Ria services" acceidentality, if so your "Include" attributes might still be on WCF RIA Services version instead of the OpenRiaServices version so it wont be recognized?
3. Double check that your query returns both the data and the included results
   • Use ToList or similar and save the result in a temporary variable that you inspect in the debugger to ensure the related data is included
4. Compile a debug build of OpenRiaService and use that to step through QueryProcessor.Process and check that it does properly detect that the query "requires flattening" and aht the "FlattenGraph" method works in your scenario.

That said I really do reccomend that you upgrade to EF6 and OpenRiaServices 5.
The upgrade to EF6 is quite seamless you just change the code generation for your EDMX files

Daniel,

I did step through the code last night and indeed it's the QueryProcessor exiting early because it thinks that the type has no IncludeAttributes (MetaType.GetMetaType(type).IncludedAssociations.Count).

We've just lifted the existing project with the necessary Include as shown below;

[MetadataTypeAttribute(typeof(PageMetadata))] public partial class Page { internal sealed class PageMetadata { [Include] public EntityCollection<Page> ChildPages; } }

The query we're invoking in the domain service populates the ChildPages above. Is it possible to disassemble the compiled class and observe the Include attribute to ensure it's being generated on the property? Obviously we're trying to make as few changes to the domain services as possible at the moment just to get us over the line, the existing Silverlight project is around 600K lines! The plan is to get a working version and then migrate to EF 6, etc.

Thanks, Lee.

Can you double check that your "Include" attributes are from the OpenRIAServices
namespace and not accidentally from WCF RIA Services (under system. )

Closing since there is a suggested action/answer but lack of response.
