Everything I've found so far says I should be able to use WCF to call a .asmx web service that uses WS-Security. The question is how to configure the WCF-Port. I'm using WCF-BasicHttp. First of all, is that okay? Second, how to enter the user/pass properly. On the security tab, which "Security Mode" should I pick?
The only one that seems to let me enter credentials is TransportWithMessageCredential, then I can click the "Edit" button by username credentials and enter a user/pass.
But when I did, I got this:
<soap:Fault xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">

Follow-up to TomasR's post - using WS-HTTP binding:
1) BizTalk "Consume WCF Wizard" builds a custom binding file and a WS-BasicHTTP Binding file, so I changed SendPort, and manually copied over all the configurations.
Set as follows:
Security Mode: Message
Message Client Credential Type: UseName
Algorithm Suite: Basic256 [I had no idea what to put here]
I also checked two other boxes:
a) Negotiate service credential [if I don't check this, it wants a "thumbprint"]
b) Establish security context [also tried not checking this one]
2) Ran and got this error:
Description:
The adapter failed to transmit message going to send port "WcfSendPort_ValuationServicePort_ValuationServicePortSoap" with URL "http://rct3.msbexpress.net/demo/ExpressLync/ValuationService.asmx". It will be retransmitted after the retry interval specified for this Send Port.

msgRCTGetRequest(SOAP.Password) = "mypass";

Fifth attempt, about to give up and open a Microsoft ticket:
msgRCTGetRequest(WCF.UserName) = "myuser";
msgRCTGetRequest(WCF.Password) = "mypass";
msgRCTGetRequest(WCF.Action) = "GetPropertyInfoSourceRecordPolicyNum";
msgRCTGetRequest(SOAP.MethodName) = "GetPropertyInfoSourceRecordPolicyNum";
msgRCTGetRequest(SOAP.Username) = "myuser";
msgRCTGetRequest(SOAP.Password) = "mypass";
same error as fourth attempt.
According to the doc of the vendor providing the web service, I should put the user in W-Security UsernameToken element, the password in WS-Security password, and set the element's attribute to "PasswordDigest". It also says "This token should be added to the SOAP request for the Web method." I'm not sure how this translates from the old WSE3 days to the new WCF days.
Neal, for WS-Security, you need to use the WCF-WsHttp binding/Adapter. WCF-BasicHttp is only for the simpler scenarios where the WS-* protocols are not needed.
.NET 4.0 and .NET 3.5 SP1 with hotfix 971831 allow WS-Security over http transport. Try using this sample binding:
<customBinding>
<binding name="httpAndWSSecurity">
<security authenticationMode="UserNameOverTransport"
allowInsecureTransport="true"/>
<textMessageEncoding messageVersion="Soap11WSAddressingAugust2004" />
<httpTransport/>
</binding>
Also see this MSDN article on SecurityBindingElement.AllowInsecureTransport
Use custom binding, and from the BizTalk send port, click configure, then go to the right-most tab which says "Import/Export". Paste the following XML into a file (sample.config) and then import it into the configuration port. This basically saves the time of manually typing a lot of stuff on the binding tab.
<configuration>
<system.serviceModel>
<client>
<endpoint
address="http://rct3.msbexpress.net/demo/ExpressLync/ValuationService.asmx"
binding="customBinding"
bindingConfiguration="ValuationServicePortSoap12"
contract="BizTalk"
name="WcfSendPort_ValuationServicePort_ValuationServicePortSoap12"/>
</client>
<bindings>
<customBinding>
<binding name="ValuationServicePortSoap12">
<security authenticationMode="UserNameOverTransport"
messageProtectionOrder="SignBeforeEncrypt"
includeTimestamp="true"
messageSecurityVersion="WSSecurity11WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10"
requireDerivedKeys="false"
requireSignatureConfirmation="false"/>
<textMessageEncoding messageVersion="Soap11WSAddressingAugust2004"/>
<httpsTransport />
</binding>
</customBinding>
</bindings>
</system.serviceModel>
</configuration>
The above is not very intuitive (I'm still waiting for a link from Microsoft which describes this is more detail).
Then you still specify the user/pass on the credentials tab.
However, this caused a problem for us, in that the vendor's .asmx web service we were calling did not have IIS set to "requires SSL". Apparently, that is a requirement for this to work with WCF. In other words, it works fine with WSE3 calling .NET to .NET, but when trying to call WCF to .asmx, WCF has a slightly more stringent requirement.

I am struggling with this WCF error for some time now without any luck. Basically I am tying to fetch an Entity Poco with Navigation Properties and connected objects via WCF Services. My EF v6 code successfully get the poco with all the related entities from the DB
Poco debug view
but as i try to access this Entity via WCF service, i see the following error -
An error occurred while receiving the HTTP response to http://localhost:8734/Design_Time_Addresses/BusinessLogicServicesLayer/userServices/. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.

can someone please help out or point me to a correct direction
This is because when data is returned, serialization fails, causing the WCF service to stop automatically.
Solution:
We can serialize the proxy class into the entities we need before returning the data.
Here is a demo,The student class contains the navigation properties of other entities:
public Student Getstu()
{
CodeFirstDBContext codeFirstDBContext = new CodeFirstDBContext();
Student student =codeFirstDBContext.Student.Find(1);
var serializer = new DataContractSerializer(typeof(Student), new DataContractSerializerSettings()
{
DataContractResolver = new ProxyDataContractResolver()
});
using (var stream = new MemoryStream())
{
serializer.WriteObject(stream, student);
stream.Seek(0, SeekOrigin.Begin);
var stu = (Student)serializer.ReadObject(stream);
return stu;
}
}
This is the method that the client will call.
ServiceReference1.ServiceClient serviceClient = new ServiceReference1.ServiceClient();
var stu = serviceClient.Getstu();
Client-side will call successfully.
UPDATE Disabling Loading loading also solves this problem:
public class CodeFirstDBContext : DbContext
{
public CodeFirstDBContext() : base("name=DBConn")
{
this.Configuration.ProxyCreationEnabled = false;
this.Configuration.LazyLoadingEnabled = false;
Database.SetInitializer(new CreateDatabaseIfNotExists<CodeFirstDBContext>());
}
}
I'm consuming a third-party's web service with WCF. I've got a PFX certificate file that I'm attaching via the ClientCredentials.ClientCertificate.SetCertificate method. I'm using the "Message Security Version" WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10.
Everything works fine. Now the third-party's certificate is expiring so they've issued a new one. However, this time it's a P7B file with just the public key.
When I try to use this certificate, I get a NotSupportedException with the message "The private key is not present in the X.509 certificate."
No part of my code is supplying the private key password, so I'm assuming this means that the private key is not being used. If this is the case, how can I consume this web service using only the public key? Or have I misunderstood something? (very likely)
EDIT
Ok, here's some code. The service client class I'm using was generated by svcutil and has been modified via a partial class to implement IDisposable. These are the relevant fragments:
private ServiceResponse CallService(ServiceParameters serviceParameters)
{
...
using (var client = new ThirdPartyServiceClient())
{
SetClientCredentials(client);
client.RemoteCall(serviceParameters);
}
...
}
private void SetClientCredentials(ThirdPartyServiceClient client)
{
if (client.ClientCredentials == null)
{
throw new InvalidOperationException("ClientCredentials was null and certificate could not be set");
}
client.ClientCredentials.ClientCertificate.SetCertificate(
StoreLocation.LocalMachine,
StoreName.My,
X509FindType.FindBySubjectName,
_configuration.CertificateSubject);
}
And this is my WCF config:
<system.serviceModel>
<bindings>
<customBinding>
<binding name="ThirdPartyServiceBinding">
<security includeTimestamp="true" enableUnsecuredResponse="true" authenticationMode="CertificateOverTransport" messageSecurityVersion="WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10" />

[back up the normal call hierarchy of my code]
With message security, you sign a document with your private key, and you encrypt a document with the other parties public key. They can decrypt it with their private key, and they can verify your signature with your public key. It sounds like they replaced their key so they provided you their new public key. If their public key doesn't have a publicly verifiable chain of trust, then you need to install their public key in your local certificate store as a trusted key. If you don't do this and they aren't publicly verifiable, you will get an exception about being unable to verify the chain trust. If it is your key which is expiring, then they need a public key to identify you, and you need the private half which they shouldn't have.
I have a windows phone app that allows the user to interact with it. Each interaction will always result in an async WCF call.
In addition to that, some interactions will result in opening the browser, maps, email, etc...
The problem is that, when hitting the back button, I sometime get the following error
"An error (WebException) occurred while transmitting data over the HTTP channel."
with the following stack trace:
at System.ServiceModel.Channels.HttpChannelUtilities.ProcessGetResponseWebException(WebException webException, HttpWebRequest request, HttpAbortReason abortReason)
at System.ServiceModel.Channels.HttpChannelFactory.HttpRequestChannel.HttpChannelAsyncRequest.CompleteGetResponse(IAsyncResult result)

at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state)
at System.Threading.ThreadPool.WorkItem.doWork(Object o)
at System.Threading.Timer.ring()
My understanding is that it's happening because my app opened another app (browser, maps, etc) before it had the time to execute the EndMyAsyncMethod(System.IAsyncResult result). Fair enough...
What's really annoying is that it seems it should get fixed by cloning the server-side method, only making it void with the following operation contract [OperationContract(IsOneWay = true)] but I'm still getting the error.
What's worse is that the exception is thrown in a system-generated part of the code and, thus, cannot be manually caught causing the app to just crash.
I simply don't understand the need to execute an Endxxx method when it's explicitely marked as OneWay and void.
EDIT
I did find a similar issue here. It does seem that it is related to the message getting to the service (not the client callback). My next question is:
if I'm now calling a method marked AsyncPattern and OneWay, what exactly should I be waiting for on the client to be sure the message was transmitted successfully?
This is new service definition:
[OperationContract(IsOneWay = true, AsyncPattern = true)]
IAsyncResult BeginCacheQueryWithoutCallback(string param1, QueryInfoDataContract queryInfo, AsyncCallback cb, Object s);
void EndCacheQueryWithoutCallback(IAsyncResult r);
And the implementation:
public IAsyncResult BeginCacheQueryWithoutCallback(string param1, QueryInfoDataContract queryInfo, AsyncCallback cb, Object s)
{
// do some stuff
return new CompletedAsyncResult<string>("");
}
public void EndCacheQueryWithoutCallback(IAsyncResult r)
{
}
The only thing that will guarantee that message has been delivered for One-Way binding is turning on reliable messaging and ensuring that there are no communication errors (wrong address, binding, etc.) This is the list of bindings that support reliable messaging:
basicHttpBinding - RM not supported
wsHttpBinding - RM supported, not default
wsDualHttpBinding - RM implicit
netTcpBinding - RM supported, not default
For example for tcpBinding:
<binding>
<netTcpBinding>
<binding name="MyTcpBinding">
<reliableSession enabled="true" />
</binding>
</netTcpBinding>
</binding>
Or:
<customHttpBinding>
<binding configurationName="customReliableBinding">
<reliableSession ordered="true" />
</binding>
</customBinding>
Despite many searches and read articles such as this: Exploring the WCF Named Pipe Binding - Part 1(part 2 and 3 inclusively), I haven't been able to make my service work properly.
Here's my config:
<system.serviceModel>
<client>
<endpoint address="net.pipe://localhost/GlobalPositioningService"

contract="GI.Services.GlobalPositioning.Contracts.IGlobalPositioning" />
</client>

<host>
<baseAddresses>
<add baseAddress="http://localhost:8080/GlobalPositioningService/"/>
</baseAddresses>
</host>
</service>
</services>
Then, I try to test my service through Named Pipes:
[TestFixture]
public class GlobalPositioningServiceTests {
[TestFixtureSetUp]
public void SetUpHost() {
var channelFactory = new ChannelFactory<IGlobalPositioning>(binding, new EndpointAddress(address));
channelFactory.Open();
service = channelFactory.CreateChannel();
}
private const string address = "net.pipe://localhost/GlobalPositioningService";
private static readonly Binding binding = new NetNamedPipeBinding();
private static IGlobalPositioning service;
}
And I have also tried another way using a ServiceHost instance:
[TestFixtureSetUp]
public void SetUpHost() {
host = new ServiceHost(typeof(GlobalPositioningService));
host.AddServiceEndpoint(typeof(IGlobalPositioning), binding, address);
host.Open();
service = new GlobalPositioningService();
}
And I always obtain this error with stack trace:

For your information, I'm using:
Visual Studio 2010
Windows 7
NUnit
And my service is contained within a WCF Service Library.
It seems that you are attempting to do integration testing with a running instance of your service using the netNamedPipesBinding. To do this, you need to have both a service host providing an instance of your service and a service proxy instance to use for making calls to the service. You could try combining both the code in both of your sample TestFixtureSetup methods so that you are instantiating both the service host and the service proxy (the result of the CreateChannel method). For an example of how to do this, look at this blog post.
I’m calling a web service via WCF (w/ .NET 4.0) that requires basic HTTP authentication (with username and password.) over HTTPS. While, I think I’ve got everything setup correctly, I’m getting a 401 error whenever I make the call to the service. I monitored the HTTP traffic and noticed that WCF seems to be ignoring that I told it to use an authorization header with the username and password, as none is sent in the request. Here’s my configuration below. Any ideas? Thanks!
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicAuthSecured">
<security mode="Transport">
<transport clientCredentialType="Basic" />
</security>
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="https://REMOVED FOR CONFIDENTIALITY"
binding="basicHttpBinding" bindingConfiguration="BasicAuthSecured"
contract="Five9.WsAdmin" name="WsAdminPort" />
</client>
<behaviors>
<serviceBehaviors>
<behavior name="">
<serviceMetadata httpsGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
And here’s my code:
var five_9_client = new WsAdminClient();
five_9_client.ClientCredentials.UserName.UserName = “REMOVED FOR CONFIDENTIALITY";
five_9_client.ClientCredentials.UserName.Password = "REMOVED FOR CONFIDENTIALITY";
var call_log_response = five_9_client.getCallLogReport(call_log); //Bombing out here
I’m getting this exception:
{"The HTTP request is unauthorized with client authentication scheme 'Basic'. The authentication header received from the server was ''."}
With inner exception:
{"The remote server returned an error: (401) Unauthorized."}
With stack trace:

Found the solution: basically, the problem was that the header had to be attached to the current request, like so:
var base_64_encoded_credentials =
BasicHTTPAuthenticationEncoder.base_64_encode_credentials(
client.ClientCredentials.UserName.UserName, client.ClientCredentials.UserName.Password);
HttpRequestMessageProperty request = new HttpRequestMessageProperty();
request.Headers[System.Net.HttpRequestHeader.Authorization] = "Basic " + base_64_encoded_credentials;
OperationContextScope clientScope = new OperationContextScope(five_9_client.InnerChannel);
OperationContext.Current.OutgoingMessageProperties.Add(HttpRequestMessageProperty.Name, request);
It may be that the problem is that you have not set the client credential type, see http://msdn.microsoft.com/en-us/library/ms731925.aspx
Either it is not being sent at all, or the default client credential type does not send the credentials in the header.
