Error message when you update a Web reference in Visual Studio 2008

Question

Adding the web reference does not throw any errors but no C# files are generated. Therefore, I choose to run the update web reference.  The following error is returned:

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'. These members may not be derived.

Any ideas what is wrong?

Answer 1

Just taking a guess it sounds like your web service reference isn't a web service.  I would recommend that you run wsdl outside VS against your target web service and see if it works.

Answer 2

What do you mean by "run wsdl outside"?

Answer 3

When you add a web reference the IDE runs the wsdl.exe tool under the hood to generate an assembly that knows how to talk to the web service.  This is the stuff you see show up in SE.  You can run the tool manually against your service to get the same files.

C:\Program Files\Microsoft Visual Studio 9.0\VC>wsdl.exe http://localhost:8080/myapp/myservice?wsdl
Microsoft (R) Web Services Description Language Utility
[Microsoft (R) .NET Framework, Version 2.0.50727.3038]

Error: Unable to import binding 'MyServiceBinding' from namespace 'http://w
ww.example.com/MyService'.
  - Unable to import operation 'OperationName'.
  - These members may not be derived.

If you would like more help, please type "wsdl /?".

Answer 5

See if this KB article applies to you: http://support.microsoft.com/kb/820122

It can also be caused by a mistyped type or namespace name in the XML file.  If neither of these help then please post your .wsdl file so we can look at it.

Answer 6

Ok, the KB is not related, how would I post a zip file of my wsdl and schema?

Answer 7

Here is a sample wsdl with xsds that I created to reproduce the issue.

Answer 9

I have the same problem and I cannot change "parameters" to something else as described in http://developers.de/blogs/andreas_erben/archive/2007/02/02/svcutil.exe_2F00_wsdl.exe_3A00_-issue-with-message-part-name-_2200_parameters_2200_.aspx .

 

Has anyone taken this issue up with WCF support?
