TransactionFlowAttribute error with WCF Service - wcf

I have a WCF service that I have configured on my local dev environment and run through IIS using a self signed certificate so I can support SSL and transactions using a wsHttpBinding.
Everything works fine on my local Win7 machine running IIS 7.5.
I am deploying my services app to a Win2008 R2 server running IIS 7.5.
The app pool is configured for .NET 4.0 integrated.
When I run the build and deploy to my Dev server one of the services keeps throwing an InvalidOperation exception that states that the 'WebHttpBinding' my service is using doesn't have the transactionflowattribute set on it.
Here are the only 2 bindings I have configured in my web.config:
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IRetrieval" closeTimeout="infinite" openTimeout="infinite" receiveTimeout="infinite" sendTimeout="infinite" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="2147483647" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true">
<readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None" realm="" />
<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
</basicHttpBinding>
<wsHttpBinding>
<binding name="wsHttpEndpointBinding" transactionFlow="true">
<security mode="Transport">
<transport clientCredentialType="None" />
</security>
</binding>
</wsHttpBinding>
</bindings>
Why does the error say that the configured WebHttpBinding doesn't have the attribute set? I don't even have that type of binding specified in the config.
I have another service that also uses the wsHttpBinding I have declared here and that one works fine. So at this point I am pretty much stuck as to why one of them works and the other is throwing the error.
I do have the services tagged as transaction mandatory, and I have everything setup to account for that.
Anyone have any ideas why one of my services is borking and the other is fine?

WCF Binding Transport/Windows Binding Security Not Being Enforced

I'm in the process of adding SSL security with Windows authentication to a formerly unsecured IIS hosted WCF service application. To my surprise, I found that two of the service endpoints were already using a Binding with Transport and Windows security. This is confusing because the client applications consuming this service are not configured to use Transport security or Windows credentials. Here is the service config:
<binding name="LargeBuffer" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
<readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
<security mode="Transport">
<transport clientCredentialType="Windows" />
</security>
</binding>
...
<service behaviorConfiguration="WebServices.GCServiceBehavior"
name="WebServices.GCService">
<endpoint address="" binding="basicHttpBinding" name="GCSecuredEndpoint"
bindingName="largeBuffer" contract="WebServices.IGCService" />
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
When I use Visual Studio to generate the client proxy and configuration, it creates this:
<binding name="GCSecuredEndpoint" 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>
...
<endpoint address="http://devservices.mysite.com/GCService/GCService.svc"
binding="basicHttpBinding" bindingConfiguration="GCSecuredEndpoint"
contract="GCSvc.IGCService" name="GCSecuredEndpoint" />
Notice it's security mode="None" and Transport ClientCredentialType is None instead of Windows. When I call a method on the GCService it succeeds. I would expect it to first complain that I'm trying to access over http instead of https, but it doesn't. Next I would expect it to not authenticate or complain that the client endpoint doesn't match the service in terms of authentication, but it doesn't.
I have another service in the same application that I had just setup with Transport/Windows security just without all the buffer/readquota stuff. For starters, when I generate the client proxy/config in VS for this service, it automatically uses the https address, transport security, and windows authentication. If I manually change it to use None for both, as above, a call to one of the service methods does not succeed, as expected. Why is the GCService above working?
The server config has
bindingName="largeBuffer"
instead of
bindingConfiguration="LargeBuffer"
The LargeBuffer binding configuration was never being used.

Can you test a certificate-secured WCF service with SoapUI?

I have a WCF service that is:
Using the BasicHttpBinding (if you can answer for WsHttpBinding even better!)
Using TransportWithMessageCredential Security
Using X.509 Certificates for Transport and Message security
I would like to be able to test this service with SoapUI.
However, when I attempt to do so it appears that SoapUI signs more of the message than WCF expects, leading to this error (detected in the Application log after enabling ServiceModel auditing):
CryptographicException: Unable to resolve the '#id-100' URI in the signature to compute the digest.
Alternatively, when I use a WsHttpBinding I get the exception:
MessageSecurityException: The message received over Transport security has unsigned 'To' header.
Similar issues have been raised before:
WCF rejects messages with additional signed elements
http://connect.microsoft.com/VisualStudio/feedback/details/481030/wcf-signed-parts
Getting WCF to accept unsigned 'To' Header
This does not strike me as a "Java talking to MS WCF" issue - I have a Java test client working without issue. Likewise, I can use WCFStorm to test the service. However, SoapUI has become a bit of a de facto test standard, particularly for non-Windows consumers.
So, has anyone managed to overcome these issues and test a certificate-secured WCF service using SoapUI?
Thanks
I believe this issue is irresolvable, based on my own testing and a 250 bounty not yielding an answer.
The "web.config" is generated dynamically, but it's effectively matching either of the following bindings:
<wsHttpBinding>
<binding name="WSHttpBinding_ITwoWayAsync" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:10:00"
bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard"
maxBufferPoolSize="250000" maxReceivedMessageSize="250000"
messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true"
allowCookies="false">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<security mode="TransportWithMessageCredential">
<transport clientCredentialType="Certificate" proxyCredentialType="None" realm="" />
<message clientCredentialType="Certificate" negotiateServiceCredential="false"
establishSecurityContext="false"
algorithmSuite="Default" />
</security>
</binding>
</wsHttpBinding>
<basicHttpBinding>
<binding name="BasicHttpBinding_ITwoWayAsync" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:10:00"
bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
maxBufferPoolSize="250000" maxReceivedMessageSize="250000"
messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true"
allowCookies="false">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<security mode="TransportWithMessageCredential">
<transport clientCredentialType="Certificate" proxyCredentialType="None" realm="" />
<message clientCredentialType="Certificate" algorithmSuite="Default" />
</security>
</binding>
</basicHttpBinding>
This was impossible with SoapUI and I had to use another tool called WCFStorm.
I had exactly the same issue. I haven't it working with BasicHttpBinding but do have it working with WsHttpBinding. I had the error The message received over Transport security has unsigned 'To' header as well. I created a blogpost for solving this issue. Se the blogpost Connect SoapUI to WCF service certificate authentication for more information.
You have to set the parts in the signature. By default SoapUI signs the whole request but that isn’t the default by WCF so we have to set the parts that we want to sign. So add as Name “To”, Namespace “http://www.w3.org/2005/08/addressing” (this is my namespace but check yours) and set Encode to “Element”. Also check the WS-A panel in your request. Check addressing and set the default "To" checkbox.
I have been able to do this with a custom binding in WCF and a PFX certificate file. I had to use a custom binding because I needed to restrict access to one certificate - which is outside the scope of this question. My certificate pfx file had both the public key and the private key. The private key was password protected. I could not get to this work with any other certificate format.
In SoapUI, I go to File -> Preferences -> SSL Settings:
-->Keystore Name: path_to_PFX_file
-->KeyStore password: your_private_key_password
Here are my web.config settings which are pretty much the same as a basicHttpBinding:
<customBinding>
<binding name="MyServiceBindingConfiguration">
<security authenticationMode="UserNameOverTransport" includeTimestamp="false" requireDerivedKeys="false" securityHeaderLayout="Lax" messageProtectionOrder="SignBeforeEncrypt" messageSecurityVersion="WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10">
<localClientSettings maxClockSkew="00:30:00" />
<localServiceSettings maxClockSkew="00:30:00" />
<secureConversationBootstrap />
</security>
<textMessageEncoding messageVersion="Soap11">
<readerQuotas maxDepth="32" maxStringContentLength="524288" maxArrayLength="524288" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
</textMessageEncoding>
<httpsTransport requireClientCertificate="true" />
</binding>
</customBinding>
Hope this helps.

Sending larger object to WCF results in 400 Bad Request

I have a unit test that sends a moderately large object to a WCF service. If I pass null for that parameter, everything works fine. When I send a populated object, I get an HTTP 400 response.
WCF tracing shows this error:
The maximum message size quota for incoming messages (65536) has been
exceeded.
However, I have cranked up the size configuration parameters in app.config for the unit test project as follows:
<basicHttpBinding>
<binding name="BasicHttpBinding_IMyAppService" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
maxBufferSize="200000000" maxBufferPoolSize="200000000" maxReceivedMessageSize="200000000"
messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
useDefaultWebProxy="true">
<readerQuotas maxDepth="32" maxArrayLength="200000000" maxStringContentLength="200000000"/>
<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None"
realm="" />
<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
</basicHttpBinding>
What am I missing in my configuration to raise the allowed message size above the 65536 seen in the error message?
UPDATE:
The web.config file for the web service host also sets the maxReceivedMessageSize to a large value (I think):
<binding name="basicHttpBindingConfig" maxReceivedMessageSize="20000000" maxBufferSize="20000000" maxBufferPoolSize="20000000">
<readerQuotas maxDepth="32" maxArrayLength="200000000" maxStringContentLength="200000000"/>
<security mode="TransportCredentialOnly">
<transport clientCredentialType="Ntlm"/>
</security>
</binding>
If I understand your question correctly, you increased the size for 'maxReceivedMessageSize' in the unit test's app.config. Actually you should make this change in the app.config/web.config of the web service which you are calling from your unit test code. If you host your web service in IIS, then it will be web.config. If you host it in windows service, then you need to make the change in the app.config (which gets moved to your .exe.config file in your bin folder.

WCF Service Reference Support Files Not Updating

I have a VS 2010 solution containing a WCF service project and a unit test project. The unit test project has a service reference to the WCF service.
Web.config for the WCF service project sets a number of binding attributes to other-than-default values:
web.config: (Specifically note maxBufferSize="20000000")
<basicHttpBinding>
<binding name="basicHttpBindingConfig" maxReceivedMessageSize="20000000" maxBufferSize="20000000" maxBufferPoolSize="20000000">
<readerQuotas maxDepth="32" maxArrayLength="200000000" maxStringContentLength="200000000"/>
<security mode="TransportCredentialOnly">
<transport clientCredentialType="Ntlm"/>
</security>
</binding>
</basicHttpBinding>
While examining this issue, I came to realize that the unit test project's service reference support files do not contain the values I would expect (i.e. the values configured in the WCF service's web.config):
configuration.svcinfo:
(Specifically note maxBufferSize="65536")
<binding hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" messageEncoding="Text" name="BasicHttpBinding_IBishopService" textEncoding="utf-8" transferMode="Buffered">
<readerQuotas maxArrayLength="16384" maxBytesPerRead="4096" maxDepth="32" maxNameTableCharCount="16384" maxStringContentLength="8192" />
<security mode="None">
<message algorithmSuite="Default" clientCredentialType="UserName" />
<transport clientCredentialType="None" proxyCredentialType="None" realm="" />
</security>
</binding>
Deleting and re-creating the service reference or updating the service reference re-creates the files, but I still end up with the same values.
Why?
Update
Here's the app.config of the client
<binding name="BasicHttpBinding_IMyService" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
maxBufferSize="200000000" maxBufferPoolSize="200000000" maxReceivedMessageSize="200000000"
messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
useDefaultWebProxy="true">
<readerQuotas maxDepth="32" maxStringContentLength="200000000" maxArrayLength="200000000"
maxBytesPerRead="200000000" maxNameTableCharCount="200000000" />
<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None"
realm="" />
<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
Same issue here and no solution after half a day messing about with config files... Changing automatically generated files is usually frowned upon, so my feeling says that "there has got to be a better way, Dennis".
UPDATE: I got my problem fixed by removing the name attribute in the binding configuration.
So your current web.config is looking like this
<basicHttpBinding>
<binding name="basicHttpBindingConfig" maxReceivedMessageSize="20000000" maxBufferSize="20000000" maxBufferPoolSize="20000000">
<readerQuotas maxDepth="32" maxArrayLength="200000000" maxStringContentLength="200000000"/>
<security mode="TransportCredentialOnly">
<transport clientCredentialType="Ntlm"/>
</security>
</binding>
</basicHttpBinding>
would become
<basicHttpBinding>
<binding maxReceivedMessageSize="20000000" maxBufferSize="20000000" maxBufferPoolSize="20000000">
<readerQuotas maxDepth="32" maxArrayLength="200000000" maxStringContentLength="200000000"/>
<security mode="TransportCredentialOnly">
<transport clientCredentialType="Ntlm"/>
</security>
</binding>
</basicHttpBinding>
I think you only need to this at the client-side. By removing the name attribute, you essentially change the default basicHttpBinding configuration for your app, as far as I understand it. Credits for this solution here.
Another update: if you name your service configuration correctly (including the namespace) it will pick up the binding configuration. So instead of
<service name="ServiceName">
you need
<service name="My.Namespace.ServiceName">
That is correct behavior. Some information included in binding are specific to only one side of the configuration and both client and server can use completely different values. Also these values are defence against Denial of Service attach so service doesn't want to show them publicly.
Those values affects only processing of incoming messages so service configures how it will handle incoming requests and client configures how it will handle incoming responses. Requests and responses can have different characteristics and different configuration. There is no need for service to be configured to accept 1MB requests if it always receives only few KB requests and returns 1MB responses.
Btw. this is WCF specific feature not related to general web services and because of that there is no standardized way to describe this in WSDL.

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?

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.
