I have a Self-hosted WCF Commandline through https with X509 certificate and I always get a Http 503 error. OS is currently Windows 8.1 with VS Community 2015. At the end, this commandline will be integrated in a Windows Service...
My C# code for WCF Service is this one:
using System;
using System.ServiceModel;
using WCF_Service_Library; //Contract and operations are defined in this library
using System.Threading;
using System.Globalization;
using System.Security.Cryptography.X509Certificates;
using System.ServiceModel.Description;
using System.Net;
using System.Diagnostics;
using System.Runtime.InteropServices;
using System.Reflection;
namespace Service_Commandline
{
class Program
{
static void Main(string[] args)
{
ServiceHost serviceHost;
//Get base Url for Web Service WCF
string addressHttps;
string CurrentDnsHostName = Dns.GetHostEntry("").HostName;
addressHttps = String.Format("https://" +CurrentDnsHostName + ":443");
BasicHttpBinding wsHttpBinding =new BasicHttpBinding();
wsHttpBinding.Security.Mode = BasicHttpSecurityMode.Transport;
serviceHost = new ServiceHost(typeof(PCsService), new Uri(addressHttps));
//Add service endpoint
Type endpoint = typeof(IPCsService);
serviceHost.AddServiceEndpoint(endpoint, wsHttpBinding, "WCF");
//Search for X509 certificate
X509Certificate2 certFound = FindX509Certificate("server");
if (certFound!=null)
serviceHost.Credentials.ServiceCertificate.Certificate=certFound;
serviceHost.Credentials.ClientCertificate.Authentication.RevocationMode = X509RevocationMode.NoCheck;
Uri uri = new Uri(serviceHost.Description.Endpoints[0].ListenUri.AbsoluteUri + "/mex");
//Add a behavior linked to Mex endpoint
ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpsGetEnabled = true;
smb.HttpsGetUrl = uri;
serviceHost.Description.Behaviors.Add(smb);
Console.Out.WriteLine("Mex address " + smb.HttpsGetUrl);
try
{
serviceHost.Open();
string address = serviceHost.Description.Endpoints[0].ListenUri.AbsoluteUri;
Console.WriteLine("Listening @ {0}", address);
//Certificate is:
Assembly assembly = typeof(Program).Assembly;
GuidAttribute attribute = (GuidAttribute)assembly.GetCustomAttributes(typeof(GuidAttribute), true)[0];
string appIdInString = attribute.Value;
Console.WriteLine("AppId is: " + appIdInString);
if (certFound != null)
{
Console.WriteLine("Certificate is: " + certFound.FriendlyName);
Console.WriteLine("Certificate thumbprint is: " + certFound.Thumbprint);
}
else
{
Console.WriteLine("No certificate used...");
}
Console.WriteLine("Press enter to close the service");
Console.ReadLine();
}
catch (CommunicationException ce)
{
Console.WriteLine("A commmunication error occurred: {0}", ce.Message);
Console.WriteLine();
}
catch (Exception ex)
{
Console.WriteLine("An unforseen error occurred: {0}", ex.Message);
Console.ReadLine();
}
finally
{
//Close WCF service whatever error found
if (serviceHost != null && serviceHost.State!=CommunicationState.Closed)
serviceHost.Close();
}
}
private static X509Certificate2 FindX509Certificate(string wCFServerName, StoreName storeName=StoreName.My, StoreLocation storeLocation=StoreLocation.LocalMachine)
{
//Find valid certificate
X509Certificate2Collection searchForCurrentServerCertificate = new X509Certificate2Collection();
X509Certificate2 certFound = new X509Certificate2();
X509Store store=null;
try
{
store = new X509Store(storeName, storeLocation);
store.Open(OpenFlags.ReadOnly);
searchForCurrentServerCertificate = store.Certificates.Find(X509FindType.FindBySubjectName, wCFServerName, true);
certFound = null;
if (searchForCurrentServerCertificate != null && searchForCurrentServerCertificate.Count > 0)
{
certFound = searchForCurrentServerCertificate[0];
}
store.Close();
}
catch (Exception)
{
if (store != null)
store.Close();
}
return certFound;
}
}
}
Output of this C# code is:
Mex address https:// dev01/WCF/mex
Listening @ https:// dev01/WCF
AppId is: f8939c9f-46e7-4d85-ba57-045e68e7fe44
Certificate is: Certificate for this app on port 443
Certificate thumbprint is: 5A26F1C44DE99C0FEB3FB89C80664B9619211696
Press enter to close the service
I've also reserved namespace with cmd:
netsh http add urlacl url= https:// +:443/WCF/ user="\Everyone"
And attach X509 certificate to port 443 with cmd:
netsh http add sslcert ipport=0.0.0.0:443 certhash=5a26f1c44de99c0feb3fb89c80664b9619211696 appid={f8939c9f-46e7-4d85-ba57-045e68e7fe44} certstorename=MY
Finally, these 2 commandlines seems ok according to these outputs:
C:\Windows\system32>netsh http show urlacl url=https:// +:443/WCF/
Réservations d'URL :
--------------------
URL reserved : https:// +:443/WCF/

And I don't have other reserved Url on https://...443:/WCF/.
Whatever I tried, I get a 503 error on https:// DEV01:443/WCF/. But mex endpoint seems to be ok on https:// DEV01:443/WCF/Mex. I get an Xml result. Only one thing seems strange for me in mex Xml: targetNamespace is equal in mex endpoint to "http:// tempuri.org/".
Please help me on this subject!

I finally found a way to have this Self-hosted Service working. I don't use anymore parameters in code. I use an app.config which defined 99% of my serviceHost configuration and just add some piece of parameters in code (like certificate management).
As far as I know this example had 0 chances to work like that! Lot of guys explain the contrary but they were wrong.
So, with app.config, my code is quite simple:
static void Main(string[] args)
{
ServiceHost serviceHost;
serviceHost = new ServiceHost(typeof(PCsService));
try
{
serviceHost.Open();
...
...
Hope it will help someone else!
Regards.
