I have a client that generates its app.config using a Service Reference to a NetTCPBinding over my localhost. For some reason when I run my service and Update the Service Reference on the client the app.config file duplicates the endpoints (incrementing the name) instead of replacing the current file.
How can I stop the client app.config from duplicating the endpoints?
Here is my service app.config:
<services>
<service name="Embedded_DCC_Service.EmbeddedService" behaviorConfiguration="serviceBehavior">
<endpoint
name ="TCPEndPoint"
binding="netTcpBinding"
contract="Embedded_DCC_Service.IEmbeddedService"
address="EmbeddedService"
bindingConfiguration="EmbeddedService_Binding"
/>
<endpoint
name ="MetaDataTcpEndpoint"
binding="mexTcpBinding"
contract="IMetadataExchange"
address="mex"
/>
<host>
<baseAddresses>
<add baseAddress="net.tcp://localhost:9292/"/>
</baseAddresses>
</host>
</service>
</services>
<bindings>
<netTcpBinding>
<binding name="EmbeddedService_Binding" closeTimeout="infinite" openTimeout="infinite"
receiveTimeout="infinite" sendTimeout="infinite" />
</netTcpBinding>
</bindings>
<behaviors>
<serviceBehaviors>
<behavior name="serviceBehavior">
<serviceMetadata httpGetEnabled="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
And the generated app.config on the client (with duplicate entries):
<?xml version="1.0" encoding="utf-8" ?>

<system.serviceModel>
