wcf - Create WCF Service application from WSDL

Question

im pretty new in programming WCF Service Applications using C#. Currently im learning and what i was trying now is create a web service application class from WSDL. First of all i created a WSDL which is looking like the WSDL at the end of the post. Now i want to use the Tool "svcUtil" in order to create my class. In the command prompt i tried to write

C:\program files (x86)\Microsoft sdks\windows\v7.0a\bin>svcutil /language:csharp "c:\users\myNick\Documents\visual studio 2010\projects\myWSDL.wsdl"

and was expecting a class file to be written in the project folder. But i always got the following error message:

"Warning: No code was generated. If you were trying to generate a client, this could be because the metadata documents did not contain any valid contracts or services or because all contracts/services were discovered to exist in /reference assemblies. Verify that you passed all the metadata documents to the tool.

Waring: if you would like to generate data contracts form schemas make sure to use the /datacontractonly option."

I was searching in internet for some help but wasn't able to figure out what is going wrong. Is anything is missing in my WSDL? From what i know everything should be there or am i wrong?

Thanks for help!

best regards
