Issues

n/a

Description

With the default MaxTop set to 0, any query that contains $top will fail. It's not very obvious how to set this default. The value supplied by ODataValidationSettings is ignored when as well.

@droyad, there appear to be four failures in the WebApiOData.E2E.AspNet test suite based on our buddy build:

Can you please address those test cases?
