Mapping large data models through OData and WebAPI

I have an EF model with approximately 200 tables, of which 75 I would like to open via REST in an MVC application. I started by adding a WCF data service (WCF-DS), pointing it to the EF and bam context, I had the whole database mapped to a REST URI with full OData syntax support in about 2 minutes.

Next, I tried to create the same REST URI space using the WebAPI. When I tried to add the WebAPI OData controller, the first thing he asked for was a model class, and when I finished creating the controller (and copying all the necessary ODataConventionModelBuilder code to WebApiConfig), I had only one REST endpoint! Now I see that WebAPI is not well suited to expose all EF models with a lot of brute force.

So my questions are:

  • Did I skip the way to map a bunch of WebAPI endpoints to an EF model in one fell swoop?

    (Maybe T4 templates that build all the WebAPI code when creating my EF model?)

  • Are there any good reasons to consider WebAPI vs WCF-DS for publishing large URI domains?

    (Some say that the benefits of WebAPI should have fine-grained control over every MVC / HTTP request, but that seems counterproductive if the goal is to meet the OData specification. I'm not sure I want to have 75 controllers and 1000 lines of code that will seduce of my fellow developers so that they change one behavior of the entity, which will lead to a different behavior from other objects.)

    (For cross-cutting issues such as security, caching, or performance management, WCF-DS seems to have sufficient configuration ability with Interceptors and the DataServiceConfiguration class. Are there any WebAPI features that would be better here?)

Thanks.
