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>

I have wide range of interests and getting my hands dirty in technology is one among them. I use this platform primarily as my knowledge base. I also use this platform to share my experience and experiments so that it might help someone who is walking the way I already did. The suggestions expressed here are the best to my knowledge at the time of writing and this may not necessarily be the best possible solution. I would pretty much appreciate if you could comment on it to bring into my notice on what could have been done better.
