How do I validate messages?  If my schema has a simpleType with facets like
"minExclusive" and "maxLength" will the .Net framework validate the message
before running the web service?  This is what one of my server stubs look
like.

<System.Web.Services.WebMethodAttribute(),  _
   
System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://me.com/xml/wsdl/AppSec/getApplicationList",
RequestElementName:="getApplicationListRequest",
RequestNamespace:="http://me.com/xml/xsd/AppSec1.xsd",
ResponseNamespace:="http://me.com/xml/xsd/AppSec1.xsd",
Use:=System.Web.Services.Description.SoapBindingUse.Literal,
ParameterStyle:=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)>  _
   Public MustOverride Function getApplicationList() As
<System.Xml.Serialization.XmlElementAttribute("apps")> application()

I would assume with all those "attributes" some sort of validation should
occur?  FYI:  I generate my server stubs using WSDL.exe, from a WSDL, that
was created with SOA Editor.

Thanks, Mike L.

Well I just noticed that "WSDL.exe" doesn't generate a type with "maxLength"
and "minLength" in the client proxy or server side stub.  WSDL.exe generates
a field instead of a property.  I know that .Net 2.0 has an option for
generating properties instead of fields.

Also those attributes do not validate the message.  In my XSD, I defined a
"complexType" that a child element that was restricted on minLength and
maxLength.  On the client, I was able to send that "complexType" with more
than 50 characters, and it went through fine.

Thanks.

Hi Mike,

The .NET framework's xml webservice (asp.net) framework doesn't provide
buildin message validation by XSD...  For customized Schema validation
through the XSD, we can utilize the SoapExtension in the ASP.NET webservice
framework. SoapExtension allow us to perform pre/post processing on
request/respone SOAP message stream. Also, we can define multiple
soapExtensions so as to chain them. Here is a msdn article mentioned using
SoapExtension to do Schema validation on ASP.NET webservice's SOAP message:

#Extend the ASP.NET WebMethod Framework by Adding XML Schema Validation
http://msdn.microsoft.com/msdnmag/issues/03/07/XMLSchemaValidation/default.a
spx

Also, some additional tech article and reference on SOAPExtension:

# Using SOAP Extensions in ASP.NET
http://msdn.microsoft.com/msdnmag/issues/04/03/ASPColumn/default.aspx

#Altering the SOAP Message Using SOAP Extensions
