WCF: Programmatically enable both https and http on same ip/port

I have read some posts here, claiming that WCF can allow http and https on the same endpoint/port, but that sounds a bit wrong to me. I tried to set it up but I cannot figure out how to enable both https and http listening on the same port/ip, programmtically.
I get the following error when I try to add https:
'System.ServiceModel.AddressAlreadyInUseException' in
System.ServiceModel.dll HTTP could not register URL
https://+:10901/Service/. Another application has already
registered this URL with HTTP.SYS.
It works fine if I add just one of them.
Code:
Uri httpsUri = new Uri("https://" + localIp.ToString() + ":" + settings._WebservicePort.ToString() + "/Service/");
Uri httpUri = new Uri("http://" + localIp.ToString() + ":" + settings._WebservicePort.ToString() + "/Service/");
host = new WebServiceHost(typeof(Service), httpUri, httpsUri);
WebHttpBinding whbHttp = new WebHttpBinding
{
CrossDomainScriptAccessEnabled = true,
Security = { Mode = WebHttpSecurityMode.None },
MaxReceivedMessageSize = 10000000
};
WebHttpBinding whbHttps = new WebHttpBinding
{
CrossDomainScriptAccessEnabled = true,
Security = { Mode = WebHttpSecurityMode.Transport },
MaxReceivedMessageSize = 10000000
};
ServiceEndpoint seHttp = host.AddServiceEndpoint(typeof(IService), whbHttp, httpUri);
seHttp.Behaviors.Add(new WebHttpBehavior());
ServiceEndpoint seHttps = host.AddServiceEndpoint(typeof(IService), whbHttps, httpsUri);
seHttps.Behaviors.Add(new WebHttpBehavior());
ServiceDebugBehavior stp = host.Description.Behaviors.Find<ServiceDebugBehavior>();
stp.HttpHelpPageEnabled = true;
host.Open(); // <-- Exception: 'System.ServiceModel.AddressAlreadyInUseException' in System.ServiceModel.dll HTTP could not register URL https://+:10901/Service/. Another application has already registered this URL with HTTP.SYS.
I realize that web http is port 80 and https is normally 443, but why am I then reading that http and https can be hosted on the same port? Am i misreading, and its actually not possible? =)

I'm not sure this is what you want. but i just go ahead and post my answer.
hosting http and https both on single port is impossible. but you can have both http and https binding like this:
<bindings>
<webHttpBinding>
<binding name="RestBinding"/>
<binding name="SecureRestBinding" >
<security mode="Transport"/>
</binding>
</webHttpBinding>
</bindings>
<services>
<service behaviorConfiguration="ServiceBehavior" name="YOURPROJECT.YOURSERVICE">
<endpoint address="" behaviorConfiguration="Web" binding="webHttpBinding" bindingConfiguration="RestBinding" name="Rest" contract="YOURPROJECT.IYOURSERVICE"/>
<endpoint address="" behaviorConfiguration="Web" binding="webHttpBinding" bindingConfiguration="SecureRestBinding" name="SecureRest" contract="YOURPROJECT.IYOURSERVICE"/>
</service>
</services>

function called twice with WCF

I am using a DuplexChannelFactory to connect my client to my server and what I want to do now is connect the server to each client that will register on the server. But every time I launch a client, my "init()" function is ran twice. And my DuplexChannelFactory on the server side doesn't work.
Here is how I open my server for clients :
host = new ServiceHost(typeof(NewServeur.NewServeur));
host.Open();
with its App.Config :
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="MEX">
<serviceMetadata />
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service behaviorConfiguration="MEX" name="NewServeur.NewServeur">
<endpoint address="IProxyNewServeur" binding="netTcpBinding"
bindingConfiguration="configWin" name="NetTcpEndpoint" contract="ProxyNewServeur.IProxyNewServeur" />
<endpoint address="MEX" binding="mexTcpBinding" bindingConfiguration=""
name="MexTcpEndpoint" contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="net.tcp://192.156.142.176:8080/" />
</baseAddresses>
</host>
</service>
</services>
<bindings>
<netTcpBinding>
<binding name="configWin">
<security mode="None"></security>
</binding>
</netTcpBinding>
</bindings>
</system.serviceModel>
Here is how I connect my client to my server :
void init()
{
ServiceCablingCallback ServiceCablingCallback = new ServiceCablingCallback();
ServiceCablingCallback.ClientNotified += ServiceCablingCallback_ClientNotified;
this._instanceContext = new InstanceContext(ServiceCablingCallback);
this.factory = new DuplexChannelFactory<ProxyNewServeur.IProxyNewServeur>(_instanceContext, "configClient");
this._serviceCablingClient = factory.CreateChannel();
this._clientId = _serviceCablingClient.Subscribe();
}
with its App.Config
<system.serviceModel>
<client>
<endpoint address="net.tcp://192.156.142.176:8080/IProxyNewServeur"
binding="netTcpBinding" bindingConfiguration="configWin" contract="ALSTEF.Cabling.ProxyNewServeur.IProxyNewServeur"
name="configClient" />
</client>
<bindings>
<netTcpBinding>
<binding name="configWin">
<security mode="None" />
</binding>
</netTcpBinding>
</bindings>
This works fine, but now I want to do the reverse thing, meaning connecting the server to the client. In order to do so, I added those lines before the last line of my client :
host = new ServiceHost(typeof(Service), new Uri(_serviceCablingClient.getIp()));
host.Open();
with getIp() returning the Ip address + the port 4242 of my client.
and this to the client App.config
<behaviors>
<serviceBehaviors>
<behavior name="MEX">
<serviceMetadata />
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service behaviorConfiguration="MEX" name="Client.Model.Service">
<endpoint address="IClientFunction" binding="netTcpBinding" bindingConfiguration="ClientConfig"
name="NetTcpEndpoint" contract="ProxyNewServeur.IClientFunction" />
<endpoint address="MEX" binding="mexTcpBinding" bindingConfiguration=""
name="MexTcpEndpoint" contract="IMetadataExchange" />
</service>
</services>
<!-- in the bindings html tag -->
<binding name="ClientConfig">
<security mode="None" />
</binding>
And I modified the _serviceCablingClient.Subscribe() by adding those lines (so in the server)
public Guid Subscribe()
{
ProxyNewServeur.INewServeurCallback callback =
OperationContext.Current.GetCallbackChannel<ProxyNewServeur.INewServeurCallback>();
System.ServiceModel.Channels.RemoteEndpointMessageProperty endpointProperty =
OperationContext.Current.IncomingMessageProperties[System.ServiceModel.Channels.RemoteEndpointMessageProperty.Name] as System.ServiceModel.Channels.RemoteEndpointMessageProperty;
Guid clientId = Guid.NewGuid();
if (callback != null)
{
lock (clientsCallback)
{
clientsCallback.Add(clientId, callback);
}
}
/* code I added */
string addr = "net.tcp://" + endpointProperty.Address + ":" + "4242" + "/IClientFunction";
ClientCallback cb = new ClientCallback();
var Okvp = new KeyValuePair<Guid, DuplexChannelFactory<ProxyNewServeur.IClientFunction>>(clientId,
new DuplexChannelFactory<ProxyNewServeur.IClientFunction>(new InstanceContext(cb), "configServer",
new EndpointAddress(addr)));
this.DictClient.Add(Okvp, Okvp.Value.CreateChannel());
this.DictClient[Okvp].CreateCallbackChannel();
/* end code I added */
}
And I added this to the server App.config
<client>
<endpoint binding="netTcpBinding" bindingConfiguration="ClientConfig" contract="ProxyNewServeur.IClientFunction" name="configServer" />
</client>
<!-- in the bindings html tag -->
<binding name="ClientConfig">
<security mode="None" />
</binding>
Here is how I define my ProxyServeur file
namespace ProxyNewServeur
{
[ServiceContract(CallbackContract = typeof(INewServeurCallback))]
public interface IProxyNewServeur
{
[OperationContract]
Guid Subscribe();
[OperationContract]
string getIp();
}
[ServiceContract]
public interface INewServeurCallback
{
[OperationContract(IsOneWay = true)]
void HandleMessage(Message message);
}
[ServiceContract(CallbackContract = typeof(IClientCallback))]
public interface IClientFunction
{
[OperationContract(IsOneWay = true)]
void CreateCallbackChannel();
}
[ServiceContract]
public interface IClientCallback
{
[OperationContract(IsOneWay = true)]
void BroadcastToServer(bool isActive, Guid ClientId);
}
}
Now When I launch a client the line
DictClient[Okvp].CreateCallbackChannel();
won't work and I will go twice in the
init()
{ /* code*/
}
function.
I have no idea why this is happening. I did the exact same thing in a test project and it worked fine.
EDIT
As it turns out, you cannot have a DuplexChannelFactory<> and a ServiceHost in the same method. So what I did is that I added a new Class "DoubleConnection" that have only one attribute.
[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall, ConcurrencyMode = ConcurrencyMode.Multiple)]
public class DoubleConnection : ProxyNewServeur.IClientFunction
{
public ServiceHost host;
public void CreateCallbackChannel()
{}
public void isActive()
{}
}
and in the init() function I removed
host = new ServiceHost(typeof(Service), new Uri(_serviceCablingClient.getIp()));
host.Open();
and added
varClass = new DoubleConnection();
varClass.host = new ServiceHost(typeof(DoubleConnection), new Uri(_serviceCablingClient.getIp()));
varClass.host.Open();
I works fine now but I still don't know why you cannot have a DuplexChannelFactory<> and a ServiceHost in the same method.

"No default endpoint found" when starting WCF client

I have a Windows Service which represents the WCF-Host and a WPF-Client-Application wich represents the WCF-Client.
The communication should be duplex so I went with WSDualHttpBinding.
At first I install and start my Service which opens a WCF connection after that I start my WPF app and I get the following error (I translated it):
No default endpoint was found to the contract
\ " WCFCloudManagerFolderWatcherService.Interfaces.IFilesDuplex \ " in the service model client configuration section
refers. This may be caused by: For the purposes of no configuration file was found
or in the client element no endpoint element was found , which corresponded to this contract .
Contracts:
IFilesDuplex-Contract:
[ServiceContract(Namespace = "http://Microsoft.ServiceModel.Samples", SessionMode = SessionMode.Required,
CallbackContract = typeof(IFilesDuplexCallback))]
public interface IFilesDuplex
{
[OperationContract(IsOneWay = true)]
void Update();
}
IFilesDuplexCallback:
interface IFilesDuplexCallback
{
[OperationContract(IsOneWay = true)]
void Equals(string[] result);
}
ClientSide
CallbackHandler:
class CallbackHandler : IFilesDuplexCallback
{
public event Action<string[]> ReceivedList = delegate { };
public void Equals(string[] result)
{
this.ReceivedList(result);
}
}
The Client itself:
class FilesDuplexClient : DuplexClientBase<IFilesDuplex>, IFilesDuplex
{
public FilesDuplexClient(InstanceContext callbackCntx)
: base(callbackCntx)
{
}
public void Update()
{
base.Channel.Update();
}
}
And the Code from the Main Window, where the error is thrown:
CallbackHandler ch = new CallbackHandler();
ch.ReceivedList += ch_ReceivedList;
// Construct InstanceContext to handle messages on callback interface
InstanceContext instanceContext = new InstanceContext(ch);
// Create a client
FilesDuplexClient client = new FilesDuplexClient(instanceContext);
client.Update();
Serverside (Windows Service)
FileProtocoll-Class (Server code)
[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
public class FileProtocoll : IFilesDuplex
{
IFilesDuplexCallback Callback
{ get { return OperationContext.Current.GetCallbackChannel<IFilesDuplexCallback>(); } }
void IFilesDuplex.Update()
{
//....
Callback.Equals(null);// just a dummy
//...
}
}
Code in the OnStart-Method (in a Thread):
// Step 1 Create a URI to serve as the base address.
Uri baseAddress = new Uri("http://localhost:8899/CloudManager/CommunicationChannel1");
// Step 2 Create a ServiceHost instance
if (selfHost != null)
{
selfHost.Close();
}
selfHost = new ServiceHost(typeof(FileProtocoll), baseAddress);
try
{
// Step 5 Start the service.
selfHost.Open();
}
catch (CommunicationException ce)
{
selfHost.Abort();
}
Code in the OnStop-Method (in a Thread):
if (selfHost != null)
{
if (selfHost.State != CommunicationState.Closed)
{
selfHost.Close();
}
selfHost = null;
}
App.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5"/>
</startup>
<system.serviceModel>
<services >
<service behaviorConfiguration="ServiceBehavior"
name="WCFCloudManagerFolderWatcherService.Communication.FileProtocoll">
<endpoint address="http://localhost:8899/CloudManager /CommunicationChannel1"
binding="wsDualHttpBinding" contract="WCFCloudManagerFolderWatcherService.Interfaces.IFilesDuplex">
<identity>
<dns value="localhost"/>
</identity>
</endpoint>

<behavior name="ServiceBehavior">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="true "/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>

I finally got it.
Had to make a few changes to my Client app.config and had to turn off security.
app.config(client):
<!-- WCF Client information-->
<system.serviceModel>
<bindings>
<wsDualHttpBinding>
<binding name="WSDualHttpBinding_IFilesDuplex">
<security mode="None"/>
</binding>
</wsDualHttpBinding>
</bindings>
<client>
<endpoint
address="http://localhost:8899/CloudManager/CommunicationChannel1"
binding="wsDualHttpBinding"
bindingConfiguration="WSDualHttpBinding_IFilesDuplex"
contract="WCFCloudManagerFolderWatcherService.Interfaces.IFilesDuplex"
name="WSDualHttpBinding_IFilesDuplex">
<identity>
<userPrincipalName value="localhost"/>
</identity>
</endpoint>
</client>
and in the app.config for the serverside I also hat to set
<security mode="None"/>
Now the connection works.

Silverlight not sending byte array to WCF service

I have webcam in a silverlight app. I capture the image and convert it to byte array and send to WCF service. Here is the image capture code:
MessageBox.Show("about to capture");
cs.CaptureImageAsync();
cs is the camera source and is configured correctly (as is the imagecapturecompleted event). On image capture completion, this code executes:
MessageBox.Show("Image Caputred");
var img = e.Result.ToImage();
var encoder = new PngEncoder();
Stream stream = img.ToStreamByExtension("png");
byte[] file = null;
if (stream.Length > 512000)
{
img = ExtendedImage.Resize(img, 240, new NearestNeighborResizer());
stream = img.ToStreamByExtension("png");
}
if (stream.Length < 512000)
{
BinaryReader binary = new BinaryReader(stream);
file = binary.ReadBytes((int)stream.Length);
MessageBox.Show("Stream read into file with length: " + file.Length);
}
else
{
MessageBox.Show("file size too large");
}
MessageBox.Show("Process done");
cs.Stop();
label1.Content = "and answer is : " + file!= null ? file.Length.ToString() : "ERROR";
ServiceReference1.Service1Client obj = new ServiceReference1.Service1Client();
ServiceReference1.ITEM i = new ServiceReference1.ITEM { Image = file };
obj.DoWorkCompleted += new EventHandler<System.ComponentModel.AsyncCompletedEventArgs>(obj_DoWorkCompleted);
obj.DoWorkAsync(i);
This is my web.config in the asp.net project that configures the service:
<system.serviceModel>
<services>
<service name ="AttendanceSystem.IService1" behaviorConfiguration="BasicHttpBinding_IService1">
<endpoint address="" binding="basicHttpBinding" contract="AttendanceSystem.IService1"/>
<endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="BasicHttpBinding_IService1">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="true"/>
And here is the reference to the service in the silverlight app
<configuration>
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IService1" maxBufferSize="2147483647"
maxReceivedMessageSize="2147483647">
<security mode="None" />
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://localhost:48886/Service1.svc" binding="basicHttpBinding"
bindingConfiguration="BasicHttpBinding_IService1" contract="ServiceReference1.IService1"
name="default" />
</client>
</system.serviceModel>
Fiddler returns the following message on the call to my .svc service file:
HTTP/1.1 400 Bad Request
Server: ASP.NET Development Server/10.0.0.0
Date: Wed, 15 Jan 2014 09:17:26 GMT
X-AspNet-Version: 4.0.30319
Cache-Control: private
Content-Length: 0
Connection: Close
So what is going on?
UPDATE: the service seems to be working without error when I pass a smaller byte array (for example BitConverter.GetBytes(123) but fails when the image is sent which is clearly within the max limits)

Try to configure the binding server-side (maxReceivedMessageSize and reader quotas)
<bindings>
<basicHttpBinding>
<binding maxReceivedMessageSize="2147483647">
<readerQuotas maxArrayLength="2147483647" maxStringContentLength="2147483647"/>
</binding>
</basicHttpBinding>
</bindings>

WCF Custom authentication - HTTP status 401: Unauthorized

Client is ASP.NET 2.0
LicensingService service = new LicensingService();
//Authentication
CredentialCache credCache = new CredentialCache();
credCache.Add(new Uri(service.Url), "Basic", new NetworkCredential("Test", "1234567"));
service.Credentials = credCache;
service.PreAuthenticate = true;
service.UseDefaultCredentials = false;
result = service.VerifyLicenseKey(licenseKey, string.Empty);
The result is always The request failed with HTTP status 401: Unauthorized. I have also turned off Anonymous Access on the folder. Its still not working.
Any ideas on how to set the credentials correctly?
EDIT: Seems like the overridden method
public override void Validate(string userName, string password)
{
try
{
if(userName != "Test" || password != "1234567")
{
throw new FaultException("The provided credentials are invalid.");
}
}
catch(FaultException ex)
{
LicensingData.Operations.LogError(ex);
}
}
is never getting hit.

Well after hours of research I found out that the hosting provider did not allow basic authentication by default. For custom authentication to work it is necessary that basic authentication be enabled in IIS.
