Consider the following scenario. You add a Web reference to a project in Microsoft Visual Studio 2005. For the Web Services Description Language (WSDL) file that describes the Web service, the first element contains a default namespace. For example, the first element resembles the following:

<xsd:schema xmlns="http://<URL>" xmlns:xsd="http://www.w3.org/2001/XMLSchema" targetNamespace="http://<URL>" elementFormDefault="qualified" attributeFormDefault="unqualified">

In this scenario, you may receive the following error message:

The custom tool ‘MSDiscoCodeGenerator’ failed. Unable to import binding ‘BindingName’ from namespace ‘http://NamespaceLocation’.

Additionally, you receive the following error message in the Error List window:

Error 1 Custom tool error: Unable to import WebService/Schema.
Unable to import binding ‘BindingName’ from namespace ‘http://NamespaceLocation’. Unable to import operation ‘OperationName’. The element ‘ElementName’ is missing.
