As a proof-of-concept, I added
expression = Microsoft.Linq.Translations.ExpressiveExtensions.WithTranslations(expression); to ExpressionConverter() just below the DebugCheck lines, and the result was, as expected, that I didn't need to call .WithTranslation() everywhere else.EF team: From a design point of view, is there a preferred way of implementing intercepting filter(s) in EF6?

ref Expression parameter? Virtual function on DbContext and ObjectContext? I lean towards virtual function, because the implementer of the derived classes knows best what changes need to be made to the Expression to make the context work properly.Apart from the references in the original post, this change would also support a DRY alternative to some use cases for Extension Method Support In Lambda expression.
