Create WCF Project using existing WSDL and svcutil.exe

I'm new to creating my own websites, so you'll need to come with me if I'm using the wrong terminology.

I am trying to create a web service using WCF. The service must be built using the existing wsdl specification which can be found here:    http://www.iicmva.com/IICMVA_CoverageVerification_.NET_1.0.wsdl

I was able to use svcutil.exe to create a class using this syntax:

svcutil IICMVA_CoverageVerification_.NET_1.0.wsdl /language:VB

I was also able to successfully use it in an old WebService project using the asmx page.
But we also need to provide service with X509 certifications. After doing some research, I found it to be a big eaiser to use WCF, so I started trying to use that instead. This is when I got into trouble.

I added the class generated by svcutil.exe to an empty WCF project and modified the default Service1.svc to implement the new class. I had to do a little tweak that I really don't understand to get the project running:

Change this:

<endpoint address="" binding="basicHttpBinding" contract="AutoserviceWCF3.VerifyServiceSoap">

:

<endpoint address="" binding="basicHttpBinding" contract="VerifyServiceSoap">

The problem I immediately ran into was that starting this project and clicking on the wsdl link did not give me the complete xml that I was expecting. With my asmx page, I was able to see an XML page that looked very similar to the original wsdl linked above. In my new WCF project, I am left with the wsdl page wrapper. I can see the bindings and the main interface, but I cannot see any data definitions.

Here are the exact steps I took to get to my current status:

  • Create a new WCF project
  • Add VerifyService.vb generated by svcutil.exe
  • removed * from ReplyAction in VerifyService.vb --Get this online. Didn't seem to do anything.
  • Paste the output.config generated by svcutil.exe into web.config
  • hidden attribute of client.endpoint address in web.config
  • modify Service1.svc to implement VerifyServiceSoap

  • Change this:

    <endpoint address="" binding="basicHttpBinding" contract="AutoserviceWCF3.VerifyServiceSoap">

  • :

    <endpoint address="" binding="basicHttpBinding" contract="VerifyServiceSoap">

That's pretty much it. I've tried several different tweaks with mixed results, but I'm still no closer to getting this thing to work.

If I change the VerifyService.vb generated by svcutil.exe from this:

<System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0"), _
 System.ServiceModel.ServiceContractAttribute([Namespace]:="http://www.iicmva.com/CoverageVerification/", ConfigurationName:="VerifyServiceSoap")> _
Public Interface VerifyServiceSoap

    'CODEGEN: Generating message contract since the wrapper name (CoverageRequest) of message VerifyInsuranceRequest does not match the default value (VerifyInsurance)
    <System.ServiceModel.OperationContractAttribute(Action:="http://localhost:1101/AutoServicesWCF3/Service1", ReplyAction:=""), _
     System.ServiceModel.XmlSerializerFormatAttribute()> _
    Function VerifyInsurance(ByVal request As VerifyInsuranceRequest) As VerifyInsuranceResponse
End Interface

For this:

<ServiceContract()> _
Public Interface VerifyServiceSoap

    <OperationContract()> _
    Function VerifyInsurance(ByVal request As VerifyInsuranceRequest) As VerifyInsuranceResponse
End Interface

I can change this line of code to what I expected it to look like:

<endpoint address="" binding="basicHttpBinding" contract="AutoserviceWCF3.VerifyServiceSoap">

It also adds a few things to the wsdl link, but it's still far from complete.

There is also this code link in VerifyService.vb that seems a little off:

'CODEGEN: Generating message contract since the wrapper name (CoverageRequest) of message VerifyInsuranceRequest does not match the default value (VerifyInsurance)

These are really the only keys I have right now. Here is the project code:

Service1.svc:

Public Class Service1
    Implements AutoServiceWCF3.VerifyServiceSoap

    Public Sub New()
    End Sub

    Public Function VerifyInsurance(ByVal request As AutoServiceWCF3.VerifyInsuranceRequest) As AutoServiceWCF3.VerifyInsuranceResponse Implements AutoServiceWCF3.VerifyServiceSoap.VerifyInsurance
        Dim v As New AutoServiceWCF3.VerifyInsuranceResponse
        Return v
    End Function
End Class

VerifyService.vb:

This character limit prevents me from putting it here. It was built with this command against the wsdl file linked at the top of my post:

svcutil IICMVA_CoverageVerification_.NET_1.0.wsdl /language:VB

The svcutil used was located at C: \ Program Files \ Microsoft SDK \ Windows \ v6.0A \ bin

The generated code says: svcutil 3.0.4506.2152

Edit: After a lot of guesswork and manual modifications for the vb class generated by svcutil.exe, we were able to get something that worked. Here's what we had to do.

Replace this:

<System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0"),  _
 System.ServiceModel.ServiceContractAttribute([Namespace]:="http://www.iicmva.com/CoverageVerification/", ConfigurationName:="VerifyServiceSoap")>  _
Public Interface VerifyServiceSoap

    'CODEGEN: Generating message contract since the wrapper name (CoverageRequest) of message VerifyInsuranceRequest does not match the default value (VerifyInsurance)
    <System.ServiceModel.OperationContractAttribute(Action:="http://tempuri.org/VerifyInsurance", ReplyAction:="*"),  _
     System.ServiceModel.XmlSerializerFormatAttribute()>  _
    Function VerifyInsurance(ByVal request As VerifyInsuranceRequest) As VerifyInsuranceResponse
End Interface

with this:

<ServiceContract()> _
Public Interface VerifyServiceSoap

    <OperationContract()> _
    Function VerifyInsurance(ByVal request As VerifyInsuranceRequest) As VerifyInsuranceResponse
End Interface

Replaced everything that looked like:

<System.CodeDom.Compiler.GeneratedCodeAttribute("svcutil", "3.0.4506.2152"),  _
 System.SerializableAttribute(),  _
 System.Diagnostics.DebuggerStepThroughAttribute(),  _
 System.ComponentModel.DesignerCategoryAttribute("code"),  _
 System.Xml.Serialization.XmlTypeAttribute([Namespace]:="http://www.iicmva.com/CoverageVerification/")>  _
Partial Public Class RequestorInformationModule

with this:

<DataContract()> _
Partial Public Class RequestorInformationModule

Replaced everything that looked like:

<System.Xml.Serialization.XmlElementAttribute(Order:=0)>  _

with this:

<DataMember()> _

We also basically threw out whatever svcutil.exe created in the output.config file and ended up as our web.config file:

After making all these changes, we were able to implement the class correctly. This worries me because if the original wsdl changes and we need to reimport and implement it, we will need to redo the whole process of manually committing the file. This is about 3000 lines of code, so it took quite a long time. This seems to defeat the purpose of the wsdl file. There should be an easier way to do this. I am wondering if we were to use something other than svcutil.exe. Can anyone shed some light on what we are missing here?
