Why is the DataServiceConfiguration.AnnotationsBuilder delegate called on all requests?

Question

I would expect that the DataServiceConfiguration.AnnotationsBuilder eventhandler only got called on $metadata requests.

Any reason for this?

(I have a custom DS provider implementation)

Hi Uffe,

Thanks for the question. This is actually the intention. The delegate is supposed to be called only when there is a metadata request. We may have a bug about requests where metadata is actually created; we will have a deeper look and see if we can fix in upcoming iterations.

The actualy merging of annotations with the underlying model should not be a big performance hit but however, in the meantime to work this around you can check in the annotations delegate whether the request is for $metadata and only execute the annotations code if this is the case.

Thanks,

Thanks Turker,

Yes in my delegate I am checking the request to se if it is a $metadata request before i do my processing. I just wanted to notify you of the issue and see if there were something that I had missed.

Thanks for confirming and looking into the issue.
