I would like to use WCF service hosted in IIS (5/6) with integrated windows authentication enabled and anonymous access disabled. I tried to do this by following http://msdn.microsoft.com/en-us/library/ff648431.aspx, but getting an error saying certificate is not installed. But I don't need SSL. I don't have any clients expecting older ASMX services, so I don't need to use basicHttpBinding (and also it is not secure), so I tried to use wsHttpBinding.
How do I get wsHttpBinding with windows authentication to work without SSL? This is such a common requirement, but I couldn't find any solution for this. Can someone post the configuration for the client and the server please? I am using ASP.NET client.
My configuration below. and the exact error message is:
An error occurred while making the HTTP request to
https://mymachine/WCFTest/Service1.svc. This could be due to the fact
that the server certificate is not configured properly with HTTP.SYS
in the HTTPS case. This could also be caused by a mismatch of the
security binding between the client and the server.
I used "svcUtil" utility to generate the proxy class and configuration for the client.

I am trying to solve a WCF error found in my previous question. Basically, the error is:
The maximum string content length quota (8192) has been exceeded while reading XML data.
And someone suggested to use a services tag in my web.config to resolve my issue.
Now, I am facing a different problem. I can’t figure out how am I suppose to configure the services tag in my web.config to work correctly on my server. I always get the following error when I try to use the services tag:
The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.
Here is my web.config with the services tag added:
<system.serviceModel>
<bindings>

<binding

Please note that by removing the services tag everything works fine, but then I will not be able to resolve my original problem posted on my previous question.
so could someone please tell me if I am doing something wrong on my web.config, specifically in my services tag?!
Okay, let's tackle this:
First, you need to define a custom basicHttpBinding binding configuration with some custom settings:
<bindings>
<basicHttpBinding>
<binding name="LargeSettings"
maxBufferSize="524288"
maxBufferPoolSize="524288"
maxReceivedMessageSize="6553600">
<readerQuotas maxDepth="32" maxStringContentLength="100000"
maxArrayLength="16384" maxBytesPerRead="4096"
maxNameTableCharCount="16384" />
<security mode="None" />
</binding>
</basicHttpBinding>
</bindings>
This section needs to be in both your server-side's web.config, as well as your client side's config.
Secondly, on the server-side, you need to have a <services> tag that defines your service and its endpoints and their configuration:
<services>
<service name="YourNamespace.YourClassName"
behaviorConfiguration="ServiceWithMetadata">
<endpoint name="Default"
address="http://localhost:53931/WCF/Service1.svc"
binding="basicHttpBinding"
bindingConfiguration="LargeSettings"
contract="YourNamespace.IServiceContract" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="ServiceWithMetadata">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
Points to check:
your service name must be the fully qualified name (YourNamespace.YourClassName) of your service class - the class that implements your service contract
your service contract in the endpoint must also be the fully qualified name of your service contract (YourNamespace.IYourServiceContract)
the behaviorConfiguration of your <service> tag must reference and match exactly to the name= attribute as defined in your <behaviors> section
And thirdly, on the client side, you need something like this:
<client>
<endpoint name="Default"
address="http://localhost:53931/WCF/Service1.svc"
binding="basicHttpBinding"
bindingConfiguration="LargeSettings"
contract="ServiceReference.IYourService" />
</client>
You need to reference the endpoint defined in your service's definition on the server side, you need to use the same binding and binding configuration, and you need to use the service contract as defined in your service reference.
For those using the built in service reference, just use the .Endpoint.Binding =THE NEW BINDING
ex:
BasicHttpBinding b = new BasicHttpBinding();
b.Security.Mode = BasicHttpSecurityMode.Transport;
...
b.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
MyWebServiceReference.ServiceReferenceSoapClient objRE = new MyWebServiceReference.ServiceReferenceSoapClient("ServiceReferenceSoap", "URI");
objRE.Endpoint.Binding = b;
Use this setting for the your bindings,
<basicHttpBinding>
<binding maxReceivedMessageSize="2147483647" messageEncoding="Text" maxBufferSize="2147483647" maxBufferPoolSize="2147483647" >
<readerQuotas maxStringContentLength="525288"></readerQuotas>
</binding>
</basicHttpBinding>
I consider myself pretty expert at WCF but this has me stumped. I don't know if this is a .NET Framework 4/WCF 4 thing with it's automatic configuration or what but I am getting strange behavior. I basically have a WCF 4 WCF service hosted in IIS project. It all worked and then I went in and switched the config from basicHttpBinding to wsHttpBinding. I tried to Update the Service Reference in my consuming app and I get basicHttpBinding output in the generated config. So, of course, I dropped down and ran svcutil.exe aggainst the .svc file and same results. This is the config file (Blah substituted for name that I can't use in public):
<system.web>
<compilation debug="true" targetFramework="4.0" />
<authentication mode="Windows"></authentication>
<identity impersonate="true"/>
</system.web>
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="WSHttpEndpointBinding">
<security mode="Message">
<message clientCredentialType="Windows" />
</security>
</binding>
</wsHttpBinding>
</bindings>
<services>
<service behaviorConfiguration="Blah.Services.RONScheduler.BlahService.BlahDataServiceBehavior"
name="Blah.Services.RONScheduler.FAMService">
<endpoint address="BlahDataService" binding="wsHttpBinding" bindingConfiguration="WSHttpEndpointBinding"
name="WSHttpEndpoint" contract="Blah.Services.RONScheduler.FAMService.IBlahDataService">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
</service>

<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
This is what I get generated out before I clean out the unncessary stuff:
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IBlahDataService" 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/BlahService/BlahDataService.svc"
binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IBlahDataService"
contract="IBlahDataService" name="BasicHttpBinding_IBlahDataService" />
</client>
</system.serviceModel>
As you can see it's as if it's ignoring the wsHttpBinding setting in the config. What gives?
Have you checked your default protocol bindings, a new feature in WCF 4 ??
By default, they're in your machine.config, and should look like this:
<system.serviceModel>
<protocolMapping>
<add scheme="http" binding="basicHttpBinding" bindingConfiguration="" />
<add scheme="net.tcp" binding="netTcpBinding" bindingConfiguration=""/>
<add scheme="net.pipe" binding="netNamedPipeBinding" bindingConfiguration=""/>
<add scheme="net.msmq" binding="netMsmqBinding" bindingConfiguration=""/>
</protocolMapping>
So this kinda implies to me that if you're hitting a HTTP address, WCF 4 will use basicHttpBinding by default.
You can change those bindings in your own configs, if needed.
Found this in A Developer's Introduction to Windows Communication Foundation 4
Given the configurations you provided, my guess would be that the service name is invalid and the host falls back to default configuration.
Make sure the service name matches the implementation class name.
I came to this conclusion because the interface name is Blah.Services.RONScheduler.FAMService.IBlahDataService and the class name is Blah.Services.RONScheduler.FAMService. It looks like there is something missing after FAMService.
Scenario
I have two WCF Services combined in a single App.Config file.
I can't get the thing to run (the application compiles but fails at initialization of the services).
Question
I'm wondering whether I need to set the service name to be the same as something else that is also defined as part of the service overall?
ERROR
TypeInitializationException
{"Service 'MurexUploadObjects.ResponseService' has zero application (non-infrastructure) endpoints. This might be because no configuration file was found for your application, or because no service element matching the service name could be found in the configuration file, or because no endpoints were defined in the service element."}

The service name must be the fully qualified name of your service class, including the namespace, e.g.
<service name="YourServiceNamespace.YourService">
It can't be just anything - the name of the service class is used by ServiceHost to find the right service configuration.
I have a WCF service hosted on a windows service on my Server1. It also has IIS on this machine. I call the service from a web app and it works fine. But within this service, I have to call another WCF sevice (also hosted on a windows service) located on Server2. The security credentials are set to "Message" and "Username". I have an error like "SOAP protcol negociation failed". It's a problem with my server certificate public key that doesn't seem to be recognise. However, if I call the service on the Server2 from Server1 in a console app, it works fine.
I followed this tutorial to set up my certificates : http://www.codeproject.com/KB/WCF/wcf_certificates.aspx
Here's the config file from my service on Server1 that tries to call the second one :
<endpoint address=""

</serviceCertificate>
</clientCredentials>
</behavior>
</endpointBehaviors>
</behaviors>
And here's the config file from the web app that calls the service on Server1 :

</endpoint>
</client>
Any idea why it works if if I call it in a console app and not from my service ? Maybe it has something to do with the certificateValidationMode="ChainTrust" ?
Well, finally it was just a matter of trusting the issuer of the certificate on the client machine. It was mentioned in the tutorial and I must have missed that step. Still wonder why it worked when calling from a console app, but... anyway, it works fine now.
Thanks !
When you call the service from the console app you are in the security context of the logged in user.
When you call the service from a service running in IIS, with default settings, you are in the security context of a local account NETWORK SERVICE.
The way to fix it is probably to set impersonate=true in the system.web section of your web.config.

With this configuration in place whenever i try to upload my file,It throws as error
System.Net.WebException: The remote server returned an error: (400) Bad Request.
at System.Net.HttpWebRequest.GetResponse()
at System.ServiceModel.Channels.HttpChannelFactory.
HttpRequestChannel.HttpChannelRequest.WaitForReply(TimeSpan timeout)}
However if i change transferMode="Streamed" to "Buffered" it works as expected. I do not understand why it behaves this way. TransferMode of WCF service is streamed, so it should work with streamed.
Please tell me how to make it work with transferMode="Streamed"
Problem was with hosting WCF services.I had hosted them on Cassini(Web server which ships with VS2008) instead of IIS.Cassini does not allow streaming over HTTP.So just using IIS to host WCF services resolved this issue.
You only want to upload files to the server? In that case, have you tried using
transferMode="StreamedRequest"
instead of "Streamed" ?? Any difference?
Also, can you show us the service contract (the interface you're programming against) ?? That might also gives us a clue.
