Can we generate web service proxy class from XSD RRS feed

  • Question

  • just see this post https://social.msdn.microsoft.com/Forums/vstudio/en-US/75a9d4d8-3612-43a0-92c8-0382e8d43a8b/generate-c-code-from-xsd-files-for-use-as-wcf-service?forum=wcf

    they said it is possible but i knew that we can only create proxy c# class from wsdl.

    How we can generate proxy from xsd file because wsdl has web service location and operation details but xsd has only schema details. so how one can generate proxy from xsd file ? please share the info.

    second question

    svcutil to generate the datacontractsonly. SVCUTIL.EXE => http://msdn.microsoft.com/en-us/library/aa347733.aspx

    svcutil /dconly XSDSchemaFile.xsd /language:C#

    what this command is doing svcutil /dconly XSDSchemaFile.xsd /language:C# ?

    can we generate proxy from data contact only if it is in xsd file ?

    please share the knowledge. thanks

    As your understanding, we only could generate data contract class from xsd file, it is not enough to generate client proxy, I would suggest you create proxy from wsdl.

    >> what this command is doing svcutil /dconly XSDSchemaFile.xsd /language:C# ?

    This command will generate data contract types in C# from the local schema document XSDSchemaFile.xsd.

    >> can we generate proxy from data contact only if it is in xsd file ?

    You could generate data contract from xsd, in other words, the generated class will only contains data contract in xsd.

  • WSDL (Web Services Description Language) describes your service and its operations - what is the service called, which methods does it offer, what kind of in parameters and return values do these methods have?

    It's a description of the behavior of the service - it's functionality.

    XSD (Xml Schema Definition) describes the static structure of the complex data types being exchanged by those service methods. It describes the types, their fields, any restriction on those fields (like max length or a regex pattern) and so forth.

    It's a description of datatypes and thus static properties of the service - it's about data.

    question

    we know that we can create proxy from WSDL but is it possible to create proxy from XSD file instead of wsdl file ?

    to create proxy from WSDL we usesvcutil

    svcutil http://localhost/MyService/ClassName.svc /Language=c#
    /t:Code /out:ClassNameProxy.cs /config:ClassNameProxy.config

    if it is possible to create proxy from xsd file then which tool i need to use ?

    thanks

  • you said ;- we only could generate data contract class from xsd file, it is not enough to generate client proxy.

    i like to know when people generate data contract class from xsd file then where they use that class ?

    just like to know what is the usage of generating data contract class from xsd file ?

    in real life tell me a scenario where it will be important to generate  data contract class from xsd file ?

    thanks

  • Hi Mou_inn,

    In general, there are data contract in wsdl file. Sometime, we may import xsd in other files like below definition.

    <wsdl:import
            namespace="http://message.bloggedbychris.com/contractfirstdemo/equipment/v1"
            location="EquipmentServiceData.xsd"></wsdl:import>

    At this time, we will need wsdl and xsd file to generate client code.

    Best Regards,

    Edward
