Webapi: $select = complexProperty/complexColProperty query option is not support

[VikingsFan]

query like ?$select=Address/Line1,Address/Line2,Address/PostCode is not support
In System.Web.OData.Formatter.Serialization.SelectExpandNode
ValidatePathIsSupported function :
when segmentCount == 2, only support first segment is a Type Segment, only support paths of type 'cast/structuralOrNavPropertyOrAction'

Is there an ETA for supporting this yet? Going on two and a half years now, and it's still needed. Maybe @robward-ms can re-assign it to someone else?

Thanks!

@robward-ms Any news on this feature?

[robward-ms]

No news here; the team is focused on getting WebApi AspNetCore finished up before tackling new features.

This issue affects Azure Search as well. We are expanding the semantics of $select in our API to handle complex types.

I investigated this issue to the point where I have a sense of the scope of the fix, and it's not small. I already have a workaround in place, so unfortunately it's not worth the effort for my team to take this on. However, I did write an E2E test that will be useful for the next person who tackles this. That was surprisingly difficult too due to some EF dependencies in the E2E tests. I'll send a PR for that shortly.

@xuzhg - We're extending our Api to support Complex Properties and getting the same error during serialization. Kindly let me know if the fix that you're implementing is part of System.Web.OData v5.x and when can we expect the fix to be released

Version of System.Web.Odata being used - 5.9.0

[xuzhg]

@VenuMadhavPerumalla Thanks for letting us know your scenarios. Unfortunately, We are focus on 7.x version and 5.x is in maintenance status.
