Service hosted in IIS and work fine.
I create new windows forms project and click Add Service Reference, visual studio genetate for my config :

    <system.serviceModel>
    <bindings>
        <netTcpBinding>
            <binding name="netTcpBindingEndpoint1" closeTimeout="00:01:00"
                openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
                transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions"
                hostNameComparisonMode="StrongWildcard" listenBacklog="10"
                maxBufferPoolSize="524288" maxBufferSize="65536" maxConnections="10"
                maxReceivedMessageSize="65536">
                <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
                    maxBytesPerRead="4096" maxNameTableCharCount="16384" />
                <reliableSession ordered="true" inactivityTimeout="00:10:00"
                    enabled="false" />
                <security mode="Transport">
                    <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" />
                    <message clientCredentialType="Windows" />
                </security>
            </binding>
        </netTcpBinding>
    </bindings>
    <client>
        <endpoint address="net.tcp://localhost/CredoService/Credo.svc"
            binding="netTcpBinding" bindingConfiguration="netTcpBindingEndpoint"
            contract="CredoClient.ICredo" name="netTcpBindingEndpoint">
            <identity>
                <servicePrincipalName value="host/home" />
            </identity>
        </endpoint>
    </client>
</system.serviceModel>

In this web config:

                    <security mode="Transport">
                    <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" />
                    <message clientCredentialType="Windows" />
                </security>

but in my service

  <security mode="Message">
    <message clientCredentialType="UserName"/>
  </security>

if i change this client dont work and throw exception.
How can i fix this?

I just spotted another issue with your code. Your service isn’t picking the binding!

<endpoint address="" binding="netTcpBinding" name="netTcpBindingEndpoint"
  contract="CredoService.ICredo" />

needs to be

<endpoint address="" binding="netTcpBinding" bindingConfiguration="netTcpBinding" name="netTcpBindingEndpoint" contract="CredoService.ICredo" />

in your <services><service><endpoint> section.

That would explain why VS is going with default NetTcpBinding instead of your options.
