No it didn't:

Public Class Foo

Private BarStuff As Integer() = New Integer(10) {}
Default Public Property Bar(ByVal i As Integer) As Integer
Get
Return BarStuff(i)
End Get
Set(ByVal value As Integer)
BarStuff(i) = value
End Set
End Property
End Class

And look, in VB.NET you can have default properties indexes by more than one parameter! Can't do that with a C# indexer:

Public Class Fooz

Private BarStuff As Integer(,) = New Integer(10, 20) {}
Default Public Property Bar(ByVal i As Integer, ByVal j As Integer) As Integer
Get
Return BarStuff(i, j)
End Get
Set(ByVal value As Integer)
BarStuff(i, j) = value
End Set
End Property
End Class

Usage:

Sub Main()

Dim f As New Foo, z As New Fooz

f(3) = 5

z(4, 5) = 6
End Sub


This concludes the cross-cultural lesson for today.
