OData without IQueryable

I am thinking of using OData for my web service (based on the Web API). Unfortunately, my data source is NOT IQueryable. Instead of implementing my own IQueryable, I pretty much followed this blog post .

What I do not understand is how to get to my object data model (EDM)? Should I model EDM, for example, in Designer? Or is it just for EF, and instead I can use "simple" classes and set relationship attributes? I do not want to disclose my internal data structures, so my EDM is more like a DTO ...

As an example, I saw what I should get from EntitySetController to get an OData compatible HTTP response. I believe that I cannot use EntitySetController as I do not support IQueryable. What should I do to get the right answer?

You can create an EDM model yourself. You can use the class ODataConventionModelBuilderto create your EDM model. This tutorial contains sample code. Also, check out OData samples from here , especially ODataServiceSample and ODataCompositeKeySample. They must start you.

Alternatively, if you haven't IQueryable, you can get ODataControllerinstead EntitySetController.
