Your service should be run,then, you can set the endpoint address as your webservice address in the target application.
Additionally, When there are multi endpoints which are associated with a WCF service, you can define a primary address and then address those endpoints through a relative address. The primary address is called Base Address. You can define the base addresses as below:
<host>
<baseAddresses>
<add baseaddress="http://localhost:8080/QuickReturns" />
<add baseaddress="net.pipe://localhost/QuickReturns" />
</baseAddresses>
</host>
And the relative addresses for endpoint would be like this:
<endpoint>
name="BasicHttpBinding"
address="Exchange"
bindingsSectionName="BasicHttpBinding"
contract="IExchange" />
<endpoint>
name="NetNamedPipeBinding"
address="Exchange"
bindingsSectionName="NetNamedPipeBinding"
contract="IExchange" />
</endpoint></endpoint>
You current address is empty and this is why it is not available when you call it.
