Is there a way to identify that VB.NET is being versus VB 6.0?

It would be handy to have a compiler constant that causes VB.NET code to be
generated rather than VB 6.0 code. That way we could use one code base for
both versions of VB. Something like:

#If VBNET Then
.....VB.NET code
#Else
.....VB6 code
#End If
