ERROR - Need Help - Unable to Import

[=?Utf-8?B?dGVzaHRyYWRlQGdtYWlsLmNvbQ==?=]

Hi All,

I am still new to Webservices in .NET

Basically, This is what I am trying to accomplish. My Client has given me
the soft copy of the WSDL file and XSD Files and has asked me to create an
executable that will consume the webservice and write the output to a log
file. I do not have access to the webservice. However, they told me that I
can create a proxy class using the WSDL they provided me. When they actually
run the executable they will change the URL of the webservice dynamically
using a config file (name value pair file) that is in the production
environment.

Therefore, my job is create them an executable that will consume the
webservice. And all this I have to develop this in my desktop, compile and
give them the exe, which they will deply and test in the production
environment.

When I tried to create a proxy class in Visual Studio IDE (2003 .net) by
adding WEB REFERENCE, I get the following error.

Custom tool error: Unable to Import WebService/Schema. A schema with the
namespace 'http://www.xxxxx.com/ivms/schema/config' has already been added. I
have no clue what is causing this error and where to look for it to fix it.

Please help.
