Is it possible to use both a certificate and UserName credential type with a service? C#

I am working on a project that makes requests to an API (which I think is WCF). The API requires an X509 certificate as a credential to be able to make requests. After referencing the service for the client and trying to make some requests, I was told that my requests were also missing a UserName header credential in order to authenticate with the API. Is it possible to use both types of credentials in a request and if so would anyone know how to set it up? Sorry if this post is poorly made, this is my first post on this website.
Edit: The username header that I need is at the SOAP message level. A header in the actual SOAP xml request.
This is my program code (with personal info taken out):
using System;
using System.Security.Cryptography.X509Certificates;
using EFM_User_Service_Test.EfmUserService;
namespace EFM_User_Service_Test
{
class Program
{
static void Main(string[] args)
{
X509Certificate2 cert = new X509Certificate2("path to pfx file", "password for file");
EfmUserServiceClient client = new EfmUserServiceClient();
client.ClientCredentials.ClientCertificate.Certificate = cert;
client.ClientCredentials.UserName.UserName = "test#email.com";
client.ClientCredentials.UserName.Password = "test password";
client.Open();
AuthenticateRequestType req = new AuthenticateRequestType();
req.Email = "test#email.com";
req.Password = "test password";
AuthenticateResponseType response = client.AuthenticateUser(req);
string user_id = "";
if (response.Error != null && response.Error.ErrorCode != "0")
{
Console.WriteLine(response.Error.ErrorCode);
Console.WriteLine(response.Error.ErrorText);
} else
{
Console.WriteLine("{0} {1} is now signed in",response.FirstName,response.LastName);
Console.WriteLine("authenticated user id: "+response.UserID);
user_id = response.UserID;
}
GetUserRequestType user_req = new GetUserRequestType();
user_req.UserID = user_id;
var user_response = client.GetUser(user_req);
if (user_response.Error != null)
{
Console.WriteLine("Error Code: "+user_response.Error.ErrorCode);
Console.WriteLine("Error Text: "+user_response.Error.ErrorText);
} else
{
Console.WriteLine(user_response.User.Email);
Console.WriteLine(user_response.User.FirstName);
Console.WriteLine(user_response.User.LastName);
Console.WriteLine(user_response.User.Email);
}
client.Close();
}
}
}
and this is my App.config file for the program which seemed to be automatically generated when I added the service reference
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.2" />
</startup>
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IEfmUserService" messageEncoding="Mtom">
<security mode="TransportWithMessageCredential">
<message clientCredentialType="Certificate" />
</security>
</binding>
<binding name="BasicHttpBinding_IEfmUserService1" messageEncoding="Mtom">
<security mode="Transport" />
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="in place of actual address"
binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IEfmUserService"
contract="EfmUserService.IEfmUserService" name="BasicHttpBinding_IEfmUserService" />
</client>
</system.serviceModel>
</configuration>

In time I solved this by adding a ServiceBehavior to my app.config file. Note that in my case it's a WPF application.
<configuration>
<system.serviceModel>
<extensions>
<behaviorExtensions>
<!-- Add this -->
<add name="basicAuthenticationBehavior" type="ProjectNamespace.Behaviors.BasicAuthenticationBehaviorExtensionElement, ProjectAssemblyName, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
</behaviorExtensions>
</extensions>
<behaviors>
<!-- Add this -->
<endpointBehaviors>
<behavior name="basicAuthenticationEndpointBehavior">
<basicAuthenticationBehavior />
</behavior>
</endpointBehaviors>
</behaviors>
<bindings>
<basicHttpBinding>
<!-- After adding your service reference, your bindings appear here -->
<binding name="DMSinterfaceSoap">
<security mode="Transport" />
</binding>
</basicHttpBinding>
</bindings>
<client>
<!-- After adding your service reference, your endpoints appear here -->
<endpoint address="https://soa.example.com/dmsinterface/DMS_service.asmx" binding="basicHttpBinding" behaviorConfiguration="basicAuthenticationEndpointBehavior" ... />
</client>
</system.serviceModel>
<configuration>
The BasicAuthenticationBehaviorExtensionElement looks like this
// Add System.Configuration reference to your ExecutingAssembly
internal class BasicAuthenticationBehaviorExtensionElement : BehaviorExtensionElement
{
/// <summary>Set this property if you want to send specific headers along with each request</summary>
public static TCredentials Credentials { internal get; set; }
public override Type BehaviorType
{
get { return typeof(BasicAuthenticationEndpointBehavior); }
}
protected override object CreateBehavior()
{
return new BasicAuthenticationEndpointBehavior();
}
}
class BasicAuthenticationEndpointBehavior : IEndpointBehavior
{
public BasicAuthenticationEndpointBehavior()
{
}
public void Validate(ServiceEndpoint endpoint) { }
public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters) { }
public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher) { }
public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
{
clientRuntime.MessageInspectors.Add(new BasicAuthenticationClientMessageInspector());
}
}
class BasicAuthenticationClientMessageInspector : IClientMessageInspector
{
public object BeforeSendRequest(ref Message request, IClientChannel channel)
{
if (BasicAuthenticationBehaviorExtensionElement.Credentials != null)
{
SetRequestHeader(ref request, "USERID", BasicAuthenticationBehaviorExtensionElement.Credentials.Credential.UserName);
SetRequestHeader(ref request, "PSWD", BasicAuthenticationBehaviorExtensionElement.Credentials.Credential.Password);
}
return null;
}
private void SetRequestHeader(ref Message request, string key, string value)
{
object httpRequestMessageObject;
if (request.Properties.TryGetValue(HttpRequestMessageProperty.Name, out httpRequestMessageObject))
{
var httpRequestMessage = httpRequestMessageObject as HttpRequestMessageProperty;
if (httpRequestMessage != null)
{
httpRequestMessage.Headers[key] = (value ?? string.Empty);
}
else
{
httpRequestMessage = new HttpRequestMessageProperty();
httpRequestMessage.Headers.Add(key, (value ?? string.Empty));
request.Properties[HttpRequestMessageProperty.Name] = httpRequestMessage;
}
}
else
{
var httpRequestMessage = new HttpRequestMessageProperty();
httpRequestMessage.Headers.Add(key, (value ?? string.Empty));
request.Properties.Add(HttpRequestMessageProperty.Name, httpRequestMessage);
}
}
public void AfterReceiveReply(ref Message reply, object correlationState) { }
}
This adds the authentication header to each request, based on the object stored in static variable.
Then you can send the soap call with the authentication certificate:
#region Get Certificate
var store = new X509Store(StoreName.My, StoreLocation.CurrentUser);
store.Open(OpenFlags.ReadOnly | OpenFlags.OpenExistingOnly);
var foundCerts = store.Certificates.Find(X509FindType.FindBySerialNumber, credential.CertificateSerial, false);
if (foundCerts.Count == 0)
throw new Exceptions.NoValidCertificateException();
#endregion
#region Setup client
// Check the App.config for available endpoint configuration names
var client = new MySoapService.DMSinterfaceSoapClient("DMSinterfaceSoap.0");
if (client.Endpoint.Binding is System.ServiceModel.BasicHttpBinding basicBinding)
{
// DMSinterfaceSoap and DMSinterfaceSoap.0 are BasicHttpBindings
// The ClientCredentialType is by default set to None. You should be able to combine HttpClientCredentialTypes but sadly that's not possible.
basicBinding.Security.Transport.ClientCredentialType = System.ServiceModel.HttpClientCredentialType.Certificate;
}
else if (client.Endpoint.Binding is System.ServiceModel.Channels.CustomBinding customBinding)
{
// DMSinterfaceSoap12 and DMSinterfaceSoap12.0 are CustomBindings
// Whatever additional configuration needs to be performed
}
#endregion
// Set the USERID and PSWD header
BasicAuthenticationBehaviorExtensionElement.Credentials.Credential = credential;
// Send certificate along with request
client.ClientCredentials.ClientCertificate.Certificate = foundCerts[0];
var error = client.GetResult(req, out res);
// Clear the USERID and PSWD header
BasicAuthenticationBehaviorExtensionElement.Credentials.Credential = null;

Can I get/set data into WCF Service by Host?

I have WCF Service hosted on WindowsServiceHost (to communicate WindowsFormsApp <> WindowsServiceHost)
Is there any way get data from WCFService to WindowsServiceHost?
And in other way (set data from WindowsServiceHost to WCFService)
That is what have i done:
I've made a project of WCF Service Library, implemented interface, contracts etc.
I created new project - Windows service and added reference to project from #1 and to System.ServiceModel
Configured app.conf:
<system.serviceModel>
<bindings>
<netTcpBinding>
<binding name="netTcp">
<security mode="Message">
</security>
</binding>
</netTcpBinding>
</bindings>

<host>
<baseAddresses>
<add baseAddress="http://localhost:8079"/>
<add baseAddress="net.tcp://localhost:8090"/>
</baseAddresses>
</host>
</service>
</services>
I've hosted the WCF in OnStart method of Windows Service
protected override void OnStart(string[] args)
{
host = new ServiceHost(typeof(KSPDJOBWinWCFService.KSPDJOBWinWCFService));
host.Open();
}
Added new solution with WinformsClient app (as WCF Client) and tested communication - all working fine.
The problem is when i send a value from WinFormsClient to WCF Service, and want to read it from Windows Service aplication
Thanks for any Help.

You could hold the WCF service instance in a global variable and work with events. In this sample the WCF Service KSPDJOBWinWCFService exposes an event EventA and the Service Host will handle it. This is the place where you can process the values sent by your WCF Client.
public partial class Service : ServiceBase
{
private ServiceHost _host;
private KSPDJOBWinWCFService _instance;
protected override void OnStart(string[] args)
{
try
{
_instance = new KSPDJOBWinWCFService();
_instance.EventA += HandleEventA;
_host = new ServiceHost(_instance);
_host.Open();
}
catch (Exception ex)
{
// Logging
}
}
public void HandleEventA(object sender, CustomEventArgs e)
{
// do whatever you want here
var localVar = e.Value;
}
protected override void OnStop()
{
try
{
if (_instance != null)
{
_instance.Dispose();
}
_host.Close();
}
catch (Exception ex)
{
// Logging
}
}
}
The WCF Service then fires this event together with the values sent from the WCF client:
public class KSPDJOBWinWCFService : IKSPDJOBWinWCFService
{
public event EventHandler<CustomEventArgs> EventA;
public bool SomeWcfOperation(int value)
{
EventA?.Invoke(this, new CustomEventArgs(value));
return true;
}
}
Create event args that fulfill your needs:
public class CustomEventArgs : EventArgs
{
public int Value { get; set; }
public CustomEventArgs(int value)
{
Value = value;
}
}
You can also expose values with public properties in your WCF Service. But events are also necessary.

WCF service contract not supported in test client

I'm new to wcf and learning how to build one, with callbacks. I got an example from the following link:
http://architects.dzone.com/articles/logging-messages-windows-0
I tried implementing the wcf but when i run this in as a test by pressing f5, the test client says:
The service contract is not supported in the wcf client.

{
IRatsServiceCallback callback = OperationContext.Current.GetCallbackChannel<IRatsServiceCallback>();
if (!callBackList.Contains(callback))
{
callBackList.Add(callback);
}

IRatsServiceCallback callback = OperationContext.Current.GetCallbackChannel<IRatsServiceCallback>();

Just wondering what could be wrong here.

There's nothing wrong. The WCF Test Client is a tool which can be used to test many types of WCF services, but not all of them - duplex contracts being one category which is not supported. You'll need to create some sort of client app to test that. In your client app you'll need to write a class which implements the callback interface, so that it can receive the messages initiated by the service.
For example, this is a very simple duplex client / service which uses WCF duplex:
public class DuplexTemplate
{
[ServiceContract(CallbackContract = typeof(ICallback))]
public interface ITest
{
[OperationContract]
string Hello(string text);
}
[ServiceContract(Name = "IReallyWantCallback")]
public interface ICallback
{
[OperationContract(IsOneWay = true)]
void OnHello(string text);
}
public class Service : ITest
{
public string Hello(string text)
{
ICallback callback = OperationContext.Current.GetCallbackChannel<ICallback>();
ThreadPool.QueueUserWorkItem(delegate
{
callback.OnHello(text);
});
return text;
}
}
class MyCallback : ICallback
{
AutoResetEvent evt;
public MyCallback(AutoResetEvent evt)
{
this.evt = evt;
}
public void OnHello(string text)
{
Console.WriteLine("[callback] OnHello({0})", text);
evt.Set();
}
}
public static void Test()
{
string baseAddress = "net.tcp://" + Environment.MachineName + ":8000/Service";
ServiceHost host = new ServiceHost(typeof(Service), new Uri(baseAddress));
host.AddServiceEndpoint(typeof(ITest), new NetTcpBinding(SecurityMode.None), "");
host.Open();
Console.WriteLine("Host opened");
AutoResetEvent evt = new AutoResetEvent(false);
MyCallback callback = new MyCallback(evt);
DuplexChannelFactory<ITest> factory = new DuplexChannelFactory<ITest>(
new InstanceContext(callback),
new NetTcpBinding(SecurityMode.None),
new EndpointAddress(baseAddress));
ITest proxy = factory.CreateChannel();
Console.WriteLine(proxy.Hello("foo bar"));
evt.WaitOne();
((IClientChannel)proxy).Close();
factory.Close();
Console.Write("Press ENTER to close the host");
Console.ReadLine();
host.Close();
}
}

My question is, inside the following code when I go through the service hosted by website,
I am unable to get the culture value of ar-SA inside the Hello method of the service.
I tried my best to clarify the question here. Please let me know what else needs to be clarified.
[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, IncludeExceptionDetailInFaults = true)]
public class Server : IHelloWorld
{
#region IHelloWorld Members
public void Hello()
{
<--- problem here unable to get culture value of ar-SA here --->
Console.WriteLine(string.Format("Hello world from the server in culture {0}", Thread.CurrentThread.CurrentCulture.Name));
}
public string HelloCulture()
{
string cultureName = Thread.CurrentThread.CurrentCulture.Name;
Console.WriteLine("**************************hello**********************************");
Console.WriteLine(cultureName);
return cultureName;
}
#endregion
}

Its not really an answer why that particular code doesnt work, but why dont you just sent in the culture string and set it in your method on the WCF service?
Thats the way we usualy do it, or if its an authenticated user, just save it on the user so they can switch to any language regardless of computer config.

How to set endpoint in runtime

I have application based on this tutorial
Method I use to test connection to server (in client app):
public class PBMBService : IService
{
private void btnPing_Click(object sender, EventArgs e)
{
ServiceClient service = new ServiceClient();
tbInfo.Text = service.Ping().Replace("\n", "\r\n");
service.Close();
}
//other methods
}
Service main function:
class Program
{
static void Main(string[] args)
{
Uri baseAddress = new Uri("http://localhost:8000/PBMB");
ServiceHost selfHost = new ServiceHost(typeof(PBMBService), baseAddress);
try
{
selfHost.AddServiceEndpoint(
typeof(IService),
new WSHttpBinding(),
"PBMBService");
ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;
selfHost.Description.Behaviors.Add(smb);
selfHost.Open();
Console.WriteLine("Serwis gotowy.");
Console.WriteLine("Naciśnij <ENTER> aby zamknąć serwis.");
Console.WriteLine();
Console.ReadLine();
selfHost.Close();
}
catch (CommunicationException ce)
{
Console.WriteLine("Nastąpił wyjątek: {0}", ce.Message);
selfHost.Abort();
}
}
}
In app.config I have:
<client>
<endpoint address="http://localhost:8000/PBMB/PBMBService" binding="wsHttpBinding"
bindingConfiguration="WSHttpBinding_IService" contract="IService"
name="WSHttpBinding_IService">
<identity>
<userPrincipalName value="PPC\Pawel" />
</identity>
</endpoint>
</client>
I can change IP from here. But how can I change it during runtime (i.e. read address/IP from file)?

You can replace the service endpoint after you created your client class:
public class PBMBService : IService
{
private void btnPing_Click(object sender, EventArgs e)
{
ServiceClient service = new ServiceClient();
service.Endpoint.Address = new EndpointAddress("http://the.new.address/to/the/service");
tbInfo.Text = service.Ping().Replace("\n", "\r\n");
service.Close();
}
}

You can use the following channel factory:
using System.ServiceModel;
namespace PgAuthentication
{
public class ServiceClientFactory<TChannel> : ChannelFactory<TChannel> where TChannel : class
{
public TChannel Create(string url)
{
return CreateChannel(new BasicHttpBinding { Security = { Mode = BasicHttpSecurityMode.None } }, new EndpointAddress(url));
}
}
}
and you can use this with the following code:
Console.WriteLine(
new ServiceClientFactory<IAuthenticationChannel>()
.Create("http://crm.payamgostar.com/Services/IAuthentication.svc")
.AuthenticateUserNameAndPassWord("o", "123", "o", "123").Success);
