IDE0046: 'if' statement can be simplified

[wstaelens]

Version Used: Visual Studio 17.2.0 Preview 3.0

Steps to Reproduce:

        public override object ConvertFieldValueForStorage(object value)
        {
            if (value is Product vfetval)
            {
                return (decimal)vfetval.ID;
            }
            else
            {
                return -1m;
            }
        }

Convert to conditional expression --> IDE0046: 'if' statement can be simplified

Expected Behavior:

       return value is Product vfetval ? (decimal)vfetval.ID : -1m;

Actual Behavior:

       return value is Product vfetval ? (decimal)vfetval.ID : (object)-1m;

(object) cast is being added, while this doesn't seem to be needed.
