[Solved] An endpoint configuration section for contract could not be loaded because more than one endpoint configuration for that contract was found. Please indicate the preferred endpoint configuration section by name.

Introduction

  This fix explained here is helpful if you are using WCF and when you try to access the service, the client throws an exception like "An endpoint configuration section for contract ‘YourContract' could not be loaded because more than one endpoint configuration for that contract was found. Please indicate the preferred endpoint configuration section by name".

How to fix this exception 

  WCF service can expose more than one endpoint and client can use any of this endpoint but not more than one at a time. This type of exception occurs when you have more than one endpoint configured at your configuration file (app.config) file while adding service reference or while configuring service at client side manually. You can have only one and only endpoint for the client. If you are getting this exception then check your client side configuration file and make sure the client tag under system.serviceModel has only one endpoint configured.

<system.serviceModel>
   <client>
      <endpoint [...]>
     </endpoint>
   </client>
</system.serviceModel>
