[Bug]: IEndpointBehavior.AddBindingParameters not called when registered in AddServiceEndpoint's configureEndpoint method

Describe expected behavior

When adding an IEndpointBehavior to an endpoint, like in WCF, I would expect IEndpointBehavior's AddBindingParameters to be called before ApplyDispatchBehavior.

Describe actual behavior

In CoreWCF, the method AddBindingParameters is not called at all.

Looking through the code it looks to me like the source of the problem is that endpoint configuration is performed as part of EndpointConfiguratorEndpointBehavior's application. DispatcherBuilder.InitializeServiceHost calls AddBindingParameters only on the initial set of EndpointBehaviors (EndpointConfiguratorEndpointBehavior and EndpointAuthorizationBehavior), which doesn't include endpoints added in configureEndpoint. I'd imagine the solution should be to either not use a behavior to invoke the endpoint configuration, but rather call it right after creation or to move parameter binding to the same loop where behaviors are applied.

Which binding

NetTcp

security

None

Which .NET version

.NET 6

Which os platform

Windows

Code snippet used to reproduce the issue

app.UseServiceModel(builder =>
{
      var binding = new NetTcpBinding(CoreWCF.SecurityMode.None);
      builder.AddService<MyService>()
          .AddServiceEndpoint<MyService, IMyService>(binding, $"net.tcp://localhost:{net_tcp_port}/MyService/service", ep =>
      {
          ep.EndpointBehaviors.Add(new MyEndpointBehavior());
      })
});

Stacktrace if any

No response

For those who need a quick workaround in the meantime you can add the IEndPointBehavior in ConfigureServiceHostBase instead like this

...
builder.AddService<MyService>()
  .AddServiceEndpoint<MyService, IMyService>(binding, $"net.tcp://localhost:{net_tcp_port}/MyService/service")
  .ConfigureServiceHostBase<MyService>(serviceHost =>
  {
    serviceHost.Description.Endpoints.First(ep => ep.Contract.ContractType == typeof(IMyService)).EndpointBehaviors.Add(new MyEndpointBehavior());
  });
