Thank you for help, regards

Answer 1

There is some problem with your configuration. Server specifies DualService over net.tcp but client uses BasicHttpBinding and does not specify address. Also your client has configuration for more endpoint then your service expose and mex endpoint in DualService has incorrect contract (should be IMetadataExchange).
Only client endpoint for PhoneService looks correct.

Answer 2

Everything works, you were right :),Thank you once again , and below I am putting the correct configuration, maybe someday it will help to somebody, .. :D:D
On server side I ve corrected IMetadataExchange in endpoint :
<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" />
and I changed alittle
<behavior name="NetTcpBehavior">
<serviceMetadata/>
<serviceThrottling maxConcurrentSessions="10000" />
</behavior>
On CLIENT SIDE I deleted most genereted code in retation with DualService and added
<endpoint name=""
address="net.tcp://localhost:8731/Service/DualService/"
binding="netTcpBinding"
bindingConfiguration="DuplexBinding"
contract="IDualService" />
where binding looks like :
<netTcpBinding>
<binding name="DuplexBinding" sendTimeout="00:00:05" >
<reliableSession enabled="true" />
<security mode="None" />
</binding>
</netTcpBinding>
