WCF as a Service Reference in UWP with Security

We add as a Service Reference a WCF project. When we configure the communication client without security just all works fine.

Without security

<security mode="None" />

And now the .cs file on a UWP app without the security configuration.

var binding = new NetTcpBinding(SecurityMode.None);
binding.Security.Transport.ClientCredentialType = TcpClientCredentialType.None;
client = new ServiceReference1Client(binding, new EndpointAddress(new Uri("net.tcp://localhost:1234/ServiceReference1")));

This sentences with no security in .exe.config just works as in Windows 8.1

Adding security to .exe.config

<security mode="Transport">
    <transport clientCredentialType="Windows"/>
</security>

And now the .cs file on a UWP app with the same security configuration.

var binding = new NetTcpBinding(SecurityMode.Transport);
binding.Security.Transport.ClientCredentialType = TcpClientCredentialType.Windows;
client = new ServiceReference1Client(binding, new EndpointAddress(new Uri("net.tcp://localhost:1234/ServiceReference1")));

Running the application with security configuration thows this exception:

And here is the StrackTrace:

Questions

Edit 1

I see that with the security on .exe.config 

<security mode="Transport">
    <transport clientCredentialType="Windows"/>
</security>

The client state is in Opened, but the client.InnerChannel threw an exception of type System.PlatformNotSupportedException

As @glen-thomas said, I try this configuration:

<security mode="Transport">
    <transport clientCredentialType="None"/>
</security>

But in this case the client state is in Faultet and threw this exception

Edit 2

On the dotnet\wcf page of github, we can see that this is currently not suported.

Transport security mode of NetTcpBinding is currently not supported by uwp.You can use the basicHttpBinding instead of the NetTcpBinding. The WCF which uses the basicHttpBinding with the Windows Authentication can be consumed by the UWP.

If the security of the connection is important but not who is connecting, try enabling transport security, but set the credential type to None. This will secure the connection but allow anonymous clients to connect.

<security mode="Transport">
    <transport clientCredentialType="None"/>
</security>

Alternatively, you might be able to solve your problem by adding the Enterprise Authentication and Private Networks(Client & Server) capabilities to your UWP application.
