Duplex connection with SOAP 1.1 service - wcf

I wish to connect to a SOAP 1.1 service. The service specifies a callback interface so I must connect using the duplex wcf classes.
My problem is that basicHttpBinding is SOAP11, but does not allow duplex.
wsDualHttpBinding allows duplex, but is strictly SOAP12
I can clarify more if there is any questions, but how do I do this seemingly simple thing?

The answer is to use a custom binding with messageVersion set to Soap11WSAddressing10. You can see mine here. Be warned though that im' not quite finished debugging it:
<customBinding>
<binding name="SomeCustomerApi" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00">
<security authenticationMode="UserNameOverTransport" enableUnsecuredResponse="true" allowInsecureTransport="true"/>
<compositeDuplex clientBaseAddress="http://localhost:port"/>
<oneWay maxAcceptedChannels="2"/>
<textMessageEncoding messageVersion="Soap11WSAddressing10" maxReadPoolSize="64" maxWritePoolSize="16" writeEncoding="utf-8"/>
<httpTransport maxBufferPoolSize="524288" maxBufferSize="524288" maxReceivedMessageSize="524288"
useDefaultWebProxy="true"
authenticationScheme="Negotiate"
bypassProxyOnLocal="false"
hostNameComparisonMode="StrongWildcard"
transferMode="Buffered"
manualAddressing="false"
/>
</binding>
</customBinding>

Is there a way to retrieve requested windows username from WCF method

I am using Custom binding in my WCF services and Proxies. I am creating proxies by inheriting from DuplexClientbase. Is there a option in WCF which helps me to get the username, who invoked the method?
Here is my binding
<bindings>
<customBinding>
<binding name="CustomPipeBinding" maxConnections="10" openTimeout="01:20:00" receiveTimeout="20.00:00:00" sendTimeout="01:20:00" closeTimeout="01:20:00">
<windowsStreamSecurity protectionLevel="None" />
<namedPipeTransport maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" />
</binding>
<binding name="CustomTcpBinding" maxConnections="10" openTimeout="01:20:00" receiveTimeout="20.00:00:00" sendTimeout="00:05:00" closeTimeout="01:20:00">
<windowsStreamSecurity protectionLevel="None" />
<reliableSession />
<tcpTransport maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647"/>
</binding>
</customBinding>
</bindings>
You need to configure your service to require impersonation as outlined in this MSDN article. Since you are defining a custom binding, you'll need to add the required security element config to allow WCF to pass the Windows credentials from the client to the service.
In your service code, you'll need to access the ServiceSecurityContext.Current.WindowsIdentity static property to get what you need.

Calling SOAP UI mock service with WCF: "The provided URI scheme 'https' is invalid; expected 'http'."

A colleague of mine gave me a copy of a mock service project for SOAP UI. I can open and run this mock service fine on my machine.
It is running at address: http://localhost:8088/mockShipmentInformationService
The WSDL is provided on address: http://localhost:8088/mockShipmentInformationService_SOAPBinding?WSDL
Using the WSDL provided, I added a Service Reference to the application project. In order to test the methods calling the service, I also added the service reference to the Unit testing project.
For both projects, the following is added to the app.config:
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="ShipmentInformationService_SOAPBinding" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
useDefaultWebProxy="true">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None" realm="" />
<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://localhost:8088/mockShipmentInformationService_SOAPBinding"
binding="basicHttpBinding" bindingConfiguration="ShipmentInformationService_SOAPBinding"
contract="ShipmentInformationService.ShipmentInformationService"
name="ShipmentInformationServicePort" />
</client>
</system.serviceModel>
As you can see, the URL is using the normal http protocol, not https. Also, my security mode is set to "none". Yet, I keep on getting the following error message, when attempting to call the service method:
The provided URI scheme 'https' is invalid; expected 'http'.
Parameter name: via
What gives? Might there be some URLs defined somewhere that are wreaking havoc? Where should I look?
I just discovered that it was all in the app.config files. The application project had a wrong URL in the applicationSettings section and the URL wasn't present there for the unit testing project. I can now at least call the service, although I am having some other issues now.

WCF + net.tcp Communication Timeout problem

I have some critical problem in my project. During transaction time with (wcf + netTCP)
I was getting the exception is.
The communication object,
System.ServiceModel.Channels.ClientFramingDuplexSessionChannel,
cannot be used for communication because it is in the Faulted state.
In WCF service app.config add binding tag with timeout specification. But my transaction has been ended within 10 min. what was the problem..
<bindings>

Any one help me !!!..
I'm not sure why you think its a timeout issue? The error message doesn't suggest a timeout has ocured. Could the server be throwing an exception?
I would strongly recommend setting up WCF tracing. Its a bit involved but really worth doing as I've solved many obscure WCF issue with it.
This is not a complete answer but if you are using the client + server on the same machine you can use a named-pipe binding instead of netTcp
The binding section the configurations might look like this.
<netNamedPipeBinding>
<binding name="infiniteOpenBindingConfig" receiveTimeout="infinite" closeTimeout="infinite">
</binding>
</netNamedPipeBinding>
To keep the binding alive indefinitely the configuration above must be set both on server and client.
Try adding this to your netTcpBinding:
<reliableSession inactivityTimeout="infinite" enabled="true" />
And if that doesn't work, enable WCF tracing to find out what's killing it.

WCF can't connect to an ASMX Web Service

I'm using WCF to connect to a remote web service (asmx) for testing at this point. The remote web service is unsecured for now (no https, no user name, password). I can add the WCF service reference, and all the classes are generated ok. When I make the call to the webservice, it just hangs.
So I can connect with the SOAP UI tool and return data just fine. I'm thinking it is something wrong with my binding. Anyone see anything I'm missing?
<system.serviceModel>
<bindings>
<!-- Need to change some settings here for HTTPS and Basic Auth when those go online-->
<basicHttpBinding>
<binding name="ServiceSoap" closeTimeout="00:01:00" openTimeout="00:01:00"
receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false"
bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
useDefaultWebProxy="true">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None"

<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://<snip>/Service.asmx"

</client>
</system.serviceModel>
Requesting the wsdl endpoint does not trigger a creation of the instance of your service. If you are using a custom service host factory look at that, otherwise look at the constructor of your service implementation or debug the service method itself.

Client calls .asmx, Server exposes WCF endpoint

We have a client that has been configured to connect to an asmx service. We don't want to ask our customers to update their configuration, but we would like to upgrade our service to use WCF. Does anyone know if WCF supports this? If so, what would the configuration file look like?
Our asmx service looks like this:
<bindings>
<binding name="ATransactionSoap" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None" realm="" />
<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://.../atransaction.asmx" binding="basicHttpBinding" bindingConfiguration="ATransactionSoap" contract="ATransactionSoap" name="ATransactionSoap" />
In response to your follow-up question:
any way to use WCF without changing the URL of the service?
Yes, you can make the old .asmx url re-direct to your .svc url. It requires configuration changes on the service side as well as a change to your .asmx file. But your existing client can continue to connect unchanged in any way. See http://kaushikrabadiya.blogspot.com/2008/11/how-to-use-asmx-extension-to-handle-wcf.html.
Your client won't have to change, except to change the URL of the service.
