Question

I am following this tutorial

http://www.codeproject.com/KB/cpp/authforwebservices.aspx

They have this in the tutorial

 [SoapHeader("Authentication", Required = true)]

Warning   1   'System.Web.Services.Protocols.SoapHeaderAttribute.Required'

is obsolete: ‘This property will be
removed from a future version. The
presence of a particular header in a
SOAP message is no longer enforced’

So I am not sure what the “Required” actually referred to but it seems to not like it anymore. So do I just remove it. I am not sure since I don’t know much about SOAP and I don’t want to simple remove it and find that without it something else could go wrong.

Answer 1

The docs state:

This member is obsolete and has no functionality.

Furthermore:

In version 1.0 of the .NET Framework
SDK, the Required property indicates
whether a SOAP header must be
understood and processed by the
recipient XML Web service or XML Web
service client. If a recipient did not
process the SOAP header an exception
was thrown.

In other words, unless you’re using .NET 1.0, it’s already not doing anything – so you can safely remove it.
