An endpoint configuration section for contract 'xxx' could not be loaded because more than one end

Posted By:      Posted Date: August 21, 2010    Points: 0   Category :ASP.Net
 

Hello,

I'm trying to test calling a webservice, I've found several free ones on http://webserviceshare.com, but none of them work for me.  Some of them give example calling code in C# which I've translated to VB.NET, they're typically just two to four lines, I don't think I've translated them incorrectly.

On that I've tried is US Zip Validator.  I added a Service Reference to http://www.webservicemart.com/uszip.asmx?WSDL, called ZipService.

I then call it like so:



            Dim myZipService As ZipService.USZipSoapClient = New ZipService.USZipSoapClient()
            Dim myCity As String = myZipService.ValidateZip("27707")


I get the following error on the first line of code:

"An endpoint configuration section for contract 'ZipService.USZipSoap' could not be loaded because more than one endpoint configuration for that contract was found. Please indicate the preferred endpoint configuration section by name."


A page with information on this web service (including C# source code) is at:

more than one endpoint configuration for that contract was found

  

Hi,

This post is in continuation to the following post


http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1395496&SiteID=1&mode=1

I could resolve the later.  however after binding with namedpipe, I tried now to add an endpoint on tcp. hence I updated the host config file to the following

<configuration>

<system.serviceModel>

<services>

<service behaviorConfiguration="metadataSupport" name="WCFServiceComponent.DemoClass"

Could not find default endpoint element that references contract 'CurrencyProxy.CurrencyServiceSoap

  

Hi,

I created 2 projects in my solution:

  1. Classic asp.net web service (asmx)
  2. Class library project which references service
  3. web site project which references class library project
  4. Windows app project which references service.

Both projects were created in 3.5 framework and in Visual Studio 2008 Beta 2.

I added web service reference to Class library project. When it asked for namespace I typed "CurrencyProxy". Projects build ok, but when I run web app, Class library throws an error: Could not find default endpoint element that references contract 'CurrencyProxy.CurrencyServiceSoap' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.

I believe it has something to do with app.config in Class library project. Here is part from app.config:

 <system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="CurrencyServiceSoap" closeTimeout=

Unrecognized configuration section httpHandlers.

  
I spliced this from the webconfig of the working program into another application's webconfig. 
I have just this one error here. Is it ok to have different locations with different system.web areas
 
<?xml version="1.0"?>
			<system.web>

Debugger endpoint configuration

  
When I started my current project, I was relatively new and followed the default WCF template closely as a result.  For a while I was running it in the Visual Studio debugger, which allowed me to develop the WCF service without having to worry about deployment.  As such, I never really had to deal with web.config.Then I got to the point where I tried deploying it, and things got messy.  Long story short, I tried hosting it in a windows service, ran into some problems with regards to endpoint configuration, and had to mess around with web.config quite a bit.  After some learning I decided it would be best to do a rollback to before I had even created the windows service, and start again with a fresh windows service.I've removed the windows service and its installer from my solution, and I decided to try and run the WCF service in the debugger.  However, this did not work, and I got an error page stating the following:  No protocol binding matches the given address 'http://0.0.0.0:54467/RUSServer.svc'. Protocol bindings are configured at the Site level in IIS or WAS configuration. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.  Exception Details: System.InvalidOperationException: No protocol binding matches the given address 'h

Could not find default endpoint element that references contract

  

There are so many questions floating around here on this topic and here is one more. I am consuming a customer's webservice through a class library and this class is referenced from a web application. When I save a form on the web page, it will call the class which will consume this webservice and send data across. But I am getting the error when I save the form. I have a feeling that their service is on https instead of http.

Could not find default endpoint element that references contract 'xxx.InboundServiceSoap' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.

Could not find default endpoint element that references contract IService1 in the ServiceModel clien

  

Hi,

I am getting the above error. When I try to generate the proxy using svcutil, I get an error  as:

"There was an error importing a wsdl:binding that the wsdl:port is dependent on"..

But the proxy .cs file is generated.

The host is running perfectly and I can view the wsdl.

Can someone help me out with this ?

Also is there any example available somewhere that I can use. I tried using MSDN Virtual lab example but I am getting the same error with it too.

 

Thanks,

Akhil Jindal


"Could not find default endpoint element that references contract " @ Expression Blend @ Design Time

  

so, in Expression Blend, and only there, during design time i get an error:

"System.InvalidOperationException was unhandled by user code

Could not find default endpoint element that references contract 'GBAUploadService.IGBAUploadService' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element."

this doesn't happen in Visual Studio 2010, and of course the service itself works flawlessly.

any ideas?

 

the code triggering the exception is part of a ObjectDataProvider, which consumes a web service in code-behind:

 

  public class FileGroupsDataProvider
  {    
    public BaseUploadJob[] GetFileGroups()
    {
      if (Assembly.GetEntryAssembly() != null)
      {
        using (GBAUploadServiceClient gbaUploadServiceClient = new GBAUploadServiceClient())
        {
          BaseUploadJob[] baseUploadJobs = gbaUploadServiceClient.GetFileGroups();
          return baseUploadJobs;
        }
      }
      return null;
    }
  }


ASP.NET Configuration not opening

  

I recently upgraded to VS 2010 and downgraded to SQL Server 2005. Now when I go Website > ASP.NET Configuration nothing happens.

It's likely this has to do with the fact that when I was installing SQL Server I got the 'ASP.net Version Registration requirement' warning, as well as the 'Failed to find the ASP.net Version Registration requirement with MS IIS'.

Anyone know what I need to get ASP.NET Configuration working?


Web deployment project - web.config section replacement does not add remove tag

  

I have a web application that is actually installed as a component of a third party site.  In some configurations, I need to remove certain connection strings and re-add them.  I'm replacing this web.config section with a xml file that includes the following:

<connectionStrings>
      <remove name="MyOverridenConnection"/>
      <add connectionString="Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=MyDb;Data Source=MyServer" name="MyOverridenConnection"
           providerName="System.Data.SqlClient"/>
    </connectionStrings>

For some reason the remove tag is left out during the substitution and I end up with the following in the installed config:

<connectionStrings>
      <add connectionString="Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=MyDb;Data Source=MyServer" name="MyOverridenConnection"
           providerName="System.Data.SqlClient"/>
    </connectionStrings>

Is there any way to issue removes in replaced sec

Class To Contract: Enrich Your XML Serialization With Schema Providers In The .NET Framework

  

The Microsoft .NET Framework 1.x provided minimal options for mapping classes to schemas and serializing objects to XML documents, making this sort of mapping quite a challenge. The .NET Framework 2.0 changes all this with Schema providers and the IXmlSerializable interface.
