How to setup proxy Credentials using HttpTransportBindingElement on WCF?

I coded a WCF Service using HttpTransportBindingElement in conjunction with IIS on port 80.
The code works fine as long as no proxy is used. But if a customer has a http-proxy the communication between WCF-Client and Server does not work in this case by occuring following error:
'There was no endpoint listening at ... that could accept the message. This is often caused by an incorrect address or SOAP action.'
It is essential to use settings by code ONLY!
here is my code approach for that issue but i stuck on it:
bool SendClientRequest(Action<ICustomerService> channel)
{
string proxy ="my.proxy.domain:8080";
string user = "user1";
string password="secret";
// maybe i do not need this 3 lines!
WebProxy webproxy = new WebProxy(proxy, true);
webproxy.Credentials = new NetworkCredential(user, password);
WebRequest.DefaultWebProxy = webproxy;
CustomBinding customBinding = new CustomBinding();
customBinding.Elements.Add(new HttpTransportBindingElement()
{
AuthenticationSchemes.None : AuthenticationSchemes.Basic,
ProxyAddress = string.IsNullOrEmpty(proxy) ? null : new Uri(proxy),
UseDefaultWebProxy = false,
BypassProxyOnLocal = true,
TransferMode = TransferMode.Streamed,
MaxReceivedMessageSize = 84087406592,
MaxBufferPoolSize = 0x1000000,
MaxBufferSize = 0x1000000
});
using (ChannelFactory<ICustomerService> factory = new
ChannelFactory<ICustomerService>(customBinding ))
{
IClientChannel contextChannel = null;
string url = "http://my.domain.de/Distribution/eService.svc",
EndpointAddress ep = new EndpointAddress(url);
ICustomerService clientChannel = factory.CreateChannel(ep);
contextChannel = clientChannel as IClientChannel;
contextChannel.OperationTimeout = TimeSpan.FromMinutes(rcvTimeout );
channel(clientChannel); // <- here i get the exception!
return true;
}
}
I tried several solution approaches but nothing seems to be specific like mine.

I think you have a few options, some of which I'll detail below.
First you could set UseDefaultWebProxy to true. This would then mean that proxy information is retrieved automatically from system proxy settings, configurable in Internet Explorer (Internet Options > Connections > LAN settings > Proxy server). This may be appropriate if you don't need to specify credentials for proxy use.
Another approach that's worked for me is to use the ProxyAuthenticationScheme property within your HttpTransportBindingElement() object. This property is only available on the CustomBinding class and allows an authentication scheme to be specified that will be used to authenticate against a proxy. In conjunction with this, the proxy server must be set against property ProxyAddress. Last but not least, the credentials to use against the proxy should be set according to the authentication scheme used, so for example, using AuthenticationSchemes.Ntlm would mean setting the UserName and Password properties on ChannelFactory.ClientCredentials.Windows.ClientCredential or perhaps ChannelFactory.ClientCredentials.HttpDigest.ClientCredential
With the second approach, be sure to note the difference between holding credentials in the ChannelFactory for use with the remote service versus credentials used for the proxy server. I've highlighted these in the code example below for clarity:
// Example service call using a CustomBinding that is configured for client
// authentication based on a user name and password sent as part of the message.
var binding = new CustomBinding();
TransportSecurityBindingElement securityBindingElement = SecurityBindingElement.CreateUserNameOverTransportBindingElement();
var secureTransport = new HttpsTransportBindingElement();
secureTransport.UseDefaultWebProxy = false;
secureTransport.ProxyAddress = new Uri("http://some-proxy");
secureTransport.ProxyAuthenticationScheme = AuthenticationSchemes.Ntlm;
binding.Elements.Add(securityBindingElement);
binding.Elements.Add(secureTransport);
var endpointAddress = new EndpointAddress("https://some-service");
var factory = new ChannelFactory<IService>(binding, endpointAddress);
// Credentials for authentication against the remote service
factory.Credentials.UserName.UserName = "serviceUser";
factory.Credentials.UserName.Password = "abc";
// Credentials for authentication against the proxy server
factory.Credentials.Windows.ClientCredential.UserName = "domain\user";
factory.Credentials.Windows.ClientCredential.Password = "xyz";
var client = factory.CreateChannel();
client.CallMethod();

WinRT UWP Attach client Certificate to a Web Service request

Is it possible in WinRT to attach a client certificate to a SOAP client request?
In previous versions you would simply do:
MyServiceSoapClient client = new MyServiceSoapClient()
X509Certificate2 cert = CertificateHelper.GetClientCertificate();
client.ClientCredentials.ClientCertificate.Certificate = cert;
But ClientCertificate property doesn't seem to be available anymore.
How could I achieve this in UWP?
Thank you.

try this:
var client = new ServiceClient();
client.Endpoint.Address = new EndpointAddress(url);
BasicHttpBinding binding = client.Endpoint.Binding as BasicHttpBinding;
binding.Security.Mode = BasicHttpSecurityMode.Transport;
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Certificate;
client.ClientCredentials.ClientCertificate.Certificate = ...
You may edit the cert to fit your requirements :)

c# calling web service error: "The client certificate is Not provided. Specify a client certificate in client credentials"

I am trying to call a web service on my server over https from my mvc3 app. I have web services located at this address:
https:localhost/web_services/web_services.asmx
And in my code i try to connect like this:
var binding = new BasicHttpsBinding();
binding.maxbuffersize = 10000;
binding.maxbufferPoolsize = 10000;
binding.maxreceivedmessageSize= 10000;
binding.Security.Mode = System.ServiceModel.BasicHttpsSecurityMode.Transport;
binding.Security.Transport.ClientCredentialsType = HttpClientCredentialType.Certificate
var endpointAddress = new EndpointAddress("https:/localhost/web_services/web_services.asmx");
new ChannelFactory<ws_name_webreqSoap>(basicHttpsBinding, endpointAddress).CreateChannel();
var webServices = new ws_name_webreqSoapClient(basicHttpsBinding, endpointAddress);
However, when this runs on the server, i get the following message:
"The client certificate is Not provided. Specify a client certificate in client credentials"
My knowledge of HTTPS and certificates is limited. Does anyone know a solution to this?
Thanks,

You can specify the client certificate on the ChannelFactory:
var channelFactory = new ChannelFactory<ws_name_webreqSoap>(basicHttpsBinding, endpointAddress);
channelFactory.Credentials.ClientCertificate.SetCertificate("CN=client.com", StoreLocation.CurrentUser, StoreName.My);
var channel = channelFactory.CreateChannel();
// ...

The provided URI scheme 'net.tcp' is invalid; expected 'http'

I'm a newbie at WCF. I'm trying to edit existing code to use a net.tcp binding instead of a http binding. I have done this easily in test projects using the config files, but for various reasons, in the real project it is done programatically.
I made the necessary changes, and the service host seems to start correctly:
Uri baseAdress= new Uri("net.tcp://localhost:7005/MyService/");
host = new ServiceHost(typeof(MyServiceImpl), baseAdress);
host.AddServiceEndpoint(
typeof(MyService),
new NetTcpBinding(),
"");
ServiceMetadataBehavior metadataBehavior;
metadataBehavior = host.Description.Behaviors.Find<ServiceMetadataBehavior>();
if (metadataBehavior == null)
{
metadataBehavior = new ServiceMetadataBehavior();
host.Description.Behaviors.Add(metadataBehavior);
}
BindingElement bindingElement = new TcpTransportBindingElement();
CustomBinding binding = new CustomBinding(bindingElement);
host.AddServiceEndpoint(typeof(IMetadataExchange), binding, "mex");
host.Open();
So far so good. I edited the connection string client side:
string serverUri = string.Format("net.tcp://{0}:{1}/MyService", serverName, port);
MyService server = new MyServiceClient("MYS", serverUri);
But when i try to call functions from my service, i get this error:
The provided URI scheme 'net.tcp' is invalid; expected 'http'
Not quite sure what i am missing... Any hints?

WcfRestContrib: Is there any example of using a WCF REST service (with basic authentication) from a desktop client

Is there any example of using a WCF REST service with basic HTTP authentication from a desktop client?
I am using WCF REST Contrib. and authentication works fine when a use a javascript client from the browser, but when I try to use a C# Console app. I get a BasicUnauthorizedException {"You have unsuccessfully attempted to access a secure resource."}. even though I supplied the correct username and password.
WebHttpBinding binding = new WebHttpBinding();
binding.SendTimeout = TimeSpan.FromSeconds(25);
binding.Security.Mode = WebHttpSecurityMode.TransportCredentialOnly;
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;
Uri address = new Uri("http://localhost:3525/wcfrestdemo/students.svc");
WebChannelFactory<ISudentService> factory =
new WebChannelFactory<ISudentService>(binding, address);
factory.Credentials.UserName.UserName = "jon";
factory.Credentials.UserName.Password = "123";
ISudentService proxy = factory.CreateChannel();
var response = proxy.GetStudents(2010, 4, 2); //throws an error.
Any help will be appreciated.
