It's not my policy, so I don't know the details. When I was first conscripted into doing some VB, a grizzled old veteran specifically said empty strings waste memory.

So what did the VB veteran recommend instead of (myVar = "")?

When they hired a new Windows programming bureaucrat last year, he sent out a link to a published C# best practices, and it said not to do (myVar = ""). I don't think it gave a reason.

Any time no reason is given, it smells fishy to me. In this particular
case, I think the recommendation is based on a misinterpretation of an
outdated factoid. (Namely, that "" instantiates a new object, while
string.Empty does not.) I don't think the wasted-memory argument
against "" was ever correct, and I am positive it hasn't been correct
for many, many years now.
