To get an updated information to this question and comments, Microsoft states on their own page at https://docs.microsoft.com/en-us/dotnet/visual-basic/language-reference/error-messages/as-any-is-not-supported-in-declare-statements:
The Any data type was used with Declare statements in Visual Basic 6.0 and earlier versions to permit the use of arguments that could contain any type of data. Visual Basic supports overloading, however, and so makes the Any data type obsolete.
