Hello,
in .NET 1.1, only the System.Web.Mail was available. This implemenation had
fundamental flaws. For example, attachment could only be added from files,
not from Streams.
The .NET 2.0 implementation is System.Net.Mail and is much more flexible and
has a richer featureset.
Best regards,
Henning Krause

Hi,
I am hoping to find out the differences between the System.Net.Mail
and System.Web.Mail.
Can some nice folks post the differences; or some urls which show
the differences?
Great Thanks

Actually System.Net.Mail replaces System.Web.Mail, which is now marked as obsolete
Juan said:re:
It's only "obsolete" for the .Net Framework 2.0.
It's still supported in the .Net Framework 1.0 and 1.1.
The correct term when a class works in previous
versions, but not in a later one, is "deprecated".

The class is marked as obsolete using the Obsolete attribute. The correct term for a class marked
as obsolete is obsolete. You can also call it "deprecated" as some other systems use that term for
the same thing.
An obsolete class is still working, it's only recommended that it's not used. As the framework is
supposed to be able to run code compiled for previos versions, classes can't just stop working, at
least not until they have been obsolete for some version updates.

There's conflicting info on that.
See :
http://msdn2.microsoft.com/en-us/library/system.web.mail(VS.80).aspx
That page says that the classes in the System.Web.Mail namespace have been deprecated,
but all its classes have been marked as obsolete.
The namespace is not obsolete. It's deprecated.
That's because it doesn't work in the current version but works in the previous ones.
See:
http://en.wikipedia.org/wiki/Deprecated
"The deprecated feature still works in the current version of the software,
but it may raise error messages or warnings recommending an alternative practice."
and
http://www.w3.org/TR/WD-html40-970917/convent.html
"A deprecated element or attribute is one that has been outdated by newer constructs."
System.Web.Mail can be thought of as "obsolescent", but not "obsolete", since it still works.
Ymmv, of course.

The classes still work in the current version.
I think that you are confusing this with something else.
Göran Andersson said:Juan said:re:

Not at all. It's very simple. There is an Obsolete attribute. There is no Deprecated attribute.
You can mark a class as obsolete, but you can't mark it as deprecated.

That is not correct. The classes still work in the current version.

I think that you are confusing this with something else. Just because something is obsolete
doesn't in any way imply that it would not work any more.
