RCS1231 triggered while it would break the method when the method uses LINQ Query syntax

[StijnOttenVMT]

Product and Version Used:
4.10

Steps to Reproduce:
Create a method with DateTime as argument which is in turn used in a LINQ Query
Actual Behavior:

        public IQueryable<RandomObject> Function(DateTime start, DateTime end)// <-- RCS1231 
        {
            return
                from randomObject in _administrationContext.RandomObjects
                where randomObject.Start <= end
                    && randomObject.End >= start
                select randomObject;
        }

But LINQ doesn't support ref read-only in this way.
