How are classic VB string functions handled?
You have the option of leaving them as is (via reference to the Microsoft.VisualBasic namespace), or converting some of them to their closest .NET equivalent string method. Note that this may be risky if you are depending on some of the very strange quirks of the classic VB string functions (e.g., Left(x, 2) returns an empty string if x is unassigned, while .NET appropriately raises an exception when x.Substring(0, 2) is attempted).
