operator is new in 2.0?

Alexander,

C# definitely supported operator overloading from 1.0 on. I think it is
just now that VB will honor the special naming convention for operators (I
don't think that the first incarnation of VB.NET did).

Hope this helps.
 
Thank you Nicholas,

So then, the book is wrong? because it says "new in framework 2.0" instead
of "new for vb 2005"
this is exactly what is says:

For VB.NET

Public Function ToInteger() As Integer
Return Value
End Function

' Operators (new in 2.0)
Public Shared Operator +(ByVal arg1 As Cycle, ByVal arg2 As Integer) As
Cycle
arg1.Value += arg2
Return arg1
End Operator

Public Shared Operator -(ByVal arg1 As Cycle, ByVal arg2 As Integer) As
Cycle
arg1.Value -= arg2
Return arg1
End Operator

and the same for C#
//
....
public int ToInteger()
{
return Value;
}
// Operators (new in .NET 2.0)
public static Cycle operator +(Cycle arg1, int arg2)
{
arg1.Value += arg2;
return arg1;
}
public static Cycle operator -(Cycle arg1, int arg2)
{
arg1.Value -= arg2;
return arg1;
}
....
//

I just wanted to clarify this, so other readers doesn't get confused (or
fail) when the time comes to answer the exam questions.

Hello,

I'm reading this book (Self-Paced for 70-536) where it says that
operators are new both to VB:NET and C#. As far as i know operators exist
for C# since 1.x and this link says so too:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/csref/html/vclrfoperator.asp

So, the book is wrong? or am i mistaking concepts?
TIA

Alexander,

I think it depends on the context, which is ambiguous in this case. If
they mean for just VB.NET, then yes, it is right. I think that is what the
author meant, "new in the framework 2.0 for VB.NET".
