Hi,
first of all thanks for your reply.
actually you can have member variable called 'schemaLocation' but if you
tag it with this attribute
[System.Xml.Serialization.XmlAttribute
(Namespace="http://www.w3.org/2001/XMLSchema-instance";)]
the wsdl.exe doesn't like it when adding a webreference to your project.
I know how to fix it, I just don't know what the error message means,
absolutly blank here, so i was hoping that some of you xml/xsd experts out
there could help with this error in relation to the wsdl.exe tool.
thanks, @llan

uses "schemaLocation" as an element name, and that could be the source of
the problem. If you just change the publicly visible name of that string,
perhaps that will help.
