Research direction

Start by tracing the DbFunction parameter handling involved in the example LINQ query. The issue does not name files, tests, or an entry point, so first locate the query translation path for function parameters. Done means complex expressions that do not come from a query root can be accepted as DbFunction parameters and the shown query can be translated.

Description

area-query needs-design

This would be especially useful in cases where the parameters don't come from a query root and therefore cannot be rewritten using let/Select like

from r in context.GetCustomerOrderCountByYear(() => context.AddValues(-2, 3))
orderby r.Count descending
select r
