I am getting error while consuming a webservice , the IDE is able to show me wsdl, but in the next step it throws object reference error, please see below pictures for the sequence 

It was able locate webservice and pull wsdl from the service 

Shows me where the xsd will be placed before generating the schemas, no error until this point

Throws error in the final step.

Note: I tested this webservice in c# windows app, it works fine by adding service reference 

Please help, thanks in advance

Check if all the elements have proper Namespace.

Hi Vivek,

Please have a look into below article,

Export as described above with svcutil, then use your editor to add a targetNamespace attribute

  <types>
    <xsd:schema targetNamespace="xxxxx">
      <xsd:import schemaLocation="some.xsd" namespace="xxxxxx" />
    </xsd:schema>
  </types>

Hi Vivek,

The wsdl file might be referring another xsd file which you have not selected in the wizard. In the browser it does not show up any error even if there is no .xsd file in the folder. 

So try asking for the .xsd file and make sure it is on the same location as wsdl file. And wizard select both .xsd and .wsdl while consuming the web service.

Cheers

Thanks Kamlesh. I marked your reply as answer.

That worked for me and generated required schemas, orchestration and bindings.

I have added something like targetNamespace=http://any. in <xsd:schema> nodes in WSDL file

Will this create problem while receiving actual message from the service?

Do I have to add custom pipeline to add the required namespace in order to receive this message inside BizTalk ?
