more than one endpoint configuration for that contract was found - wcf

Question

I have a question about my soap services(wcf)
I implement my wcf service and all the function implement correctly at compile time
I do not have any compile time error but when i run my code I received this error message
An endpoint configuration section for contract 'test.ICore' could not be loaded because more than one endpoint configuration for that contract was found. Please indicate the preferred endpoint configuration
I think in soap services we need some change in web.config file
another point is that my project have multiple soap services.
may it cause a problem?
how can i solve this issue?
thank you so much

Answer 1

I think your problem is because of you have a multiple endpoint with the same address in your web.config file
like that
<binding name="TestSoap">
<security mode="Transport" />
</binding>
<binding name="TestSoap" />
<endpoint address="http://TestSoap/Core.svc/soap"
binding="basicHttpBinding" bindingConfiguration="Soap" contract="TestSoap.ICore"
name="TestSoap" />
<endpoint address="https://TestSoap/Core.svc/soap"
binding="basicHttpBinding" bindingConfiguration="TestSoap"
contract="TestSoap.ICore" name="TestSoap" />
you can use this example for your code.
I hople you can solve your problem

In general, an interface contract can be supported by multiple endpoints, but bindings and addresses can vary, such as this:
Server-side:
<service
name="Microsoft.ServiceModel.Samples.CalculatorService"
behaviorConfiguration="CalculatorServiceBehavior">
<endpoint address=""
binding="basicHttpBinding"
contract="Microsoft.ServiceModel.Samples.ICalculator" />
<endpoint address="secure"
binding="wsHttpBinding"
contract="Microsoft.ServiceModel.Samples.ICalculator" />
</service>
Client-side:
<client>
<endpoint name="basic"
address="http://localhost/servicemodelsamples/service.svc"
binding="basicHttpBinding"
contract="Microsoft.ServiceModel.Samples.ICalculator" />
<endpoint name="secure"
address="http://localhost/servicemodelsamples/service.svc/secure"
binding="wsHttpBinding"
contract="Microsoft.ServiceModel.Samples.ICalculator" />
</client>
In the call:
CalculatorClient client = new CalculatorClient("basic");
Console.WriteLine("Communicate with basic endpoint.");
client = new CalculatorClient("secure");
Console.WriteLine("Communicate with secure endpoint.");
