EntitySetController currently returns an IQueryable<T> for its Get() function. When supplying the $select query, it'll throw an ArgumentException stating that it is unable to convert the SelectExpandWrapper to IQueryable.
I suppose the function should be changed to return an IEnumerable instead and set the QueryableAttribute on it.
I also think the functions that return T should be adapted to utilize SingleResult<T>?
Comments: @Omar: Can you share a repro. QueryableAttribute is an action filter and it runs after the action got executed. So, if the response shape is changed later, it should not matter.
