I will.
There is another issue of assigning empty values to non string reference
types. For instance, if a CSV file is missing a value, then it is treated as
an empty string, which is fine if the target method parameter is of type
string. However, it precludes using nullable types, like int?.
Is it by design?
Thanks.
