I am using Web Api with OData. and I have an entity defined in an EF 5.0. I am sending very simple request to Controller::
$.ajax({url: \"/odata/Details
Im not sure if this is the right answer, but im assuming that the odata service is attempting to maintain a stable sort ordering by ordering on all properties within your model.
Therefore try
[Queryable(EnsureStableOrdering=false)]
