How are classic VB Collections handled?
The .NET Microsoft.VisualBasic namespace is imported as part of the conversion process; allowing your classic VB Collections to continue to work the same way as before. Instant C# only makes necessary and low-risk changes to your code without rewriting functionality in the Microsoft.VisualBasic namespace. Converting VB collections to native .NET types would require substantial code alteration and is not necessary to obtain functioning C# code.
