Please forgive my lack of experience with WCF, but I'm having an issue with it that I am having some difficulty understanding.
Another organization at the company I work at has created a web service for me to consume. I believe I have correctly added a Service Reference to my project using the WSDL they provided. Their web service is based off of an Oracle API that I know very little of, I'm not an Oracle developer.
Here is the code I used to make use of the service reference:
BasicHttpBinding basicHttpBinding = new BasicHttpBinding();
basicHttpBinding.Security.Mode = BasicHttpSecurityMode.TransportWithMessageCredential;
basicHttpBinding.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName;
EndpointAddress epa = new EndpointAddress("https://MYENDPOINT.URL");
MyServiceReference.SERVICENAME_PortTypeClient port = new MyServiceReference.SERVICENAME_PortTypeClient(basicHttpBinding, epa);
port.ClientCredentials.UserName.UserName = SERVICE_U;
port.ClientCredentials.UserName.Password = SERVICE_P;
SOAHeader header = new SOAHeader();
header.Responsibility = SERVICE_RESPONSIBILITY;
InputParameters2 ip2 = new InputParameters2();
ip2.param1 = "abcd";
ip2.param2 = "1234"
OutputParameters2 output = port.WEB_SERVICE_FUNCTION(header, ip2);
Here the information in my Web.Config file regarding the binding information:
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="SERVICENAME_Binding">
<security mode="None" />
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="https://MYENDPOINT.URL"
binding="basicHttpBinding" bindingConfiguration="SERVICENAME_Binding"
contract="MyServiceReference.SERVICENAME_PortType"
name=SERVICENAME_Port" />
</client>
</system.serviceModel>
When the call is made to the service I get the following error:
Security processor was unable to find a security header in the
message. This might be because the message is an unsecured fault or
because there is a binding mismatch between the communicating parties.
This can occur if the service is configured for security and the
client is not using security.
With the following stacktrace:

After looking at the stack trace, it appears that the verification of the response may be the issue which lead me to believe that it may have to do with a timestamp issue that others have had (ex. http://blog.latamhub.com/?p=78) may be the issue, but when I try to add the includeTimestamp="true" attribute to the security tag in the Web.Config file, VS2012 reports that the includeTimestamp attribute is not allowed. Not quite certain what is going on here or what else to check. Any help or ideas are greatly appreciated.
Thanks.
EDIT (2013-05-30):
Tried the following custom binding with the includeTimestamp set to true and false with no success:
<customBinding>
<binding name="SERVICENAME_Binding">
<security
includeTimestamp="true"
/>
</binding>
</customBinding>

I have a WCF service running on a virtual machine. I haven't changed anything on this server or the service in quite some time. When I try to send up a file through the service that is ~25 mb I am getting this:

When I send up a smaller file, such as a 1mb file, I have no issues. I have tested this on several computers and I get the same results.
Any suggestions?
There are 3 things that you can change in order to make it work :
IIS Host Settings:
I believe you have hosted the WCF service in IIS. Hence you need to set the
When sending large amounts of data you will need to set the maxAllowedContentLength IIS setting (for more information see Configuring IIS Request Limits)
This value defaults to ~28MB as far as I know.
Max Received Message Size:
You will have to change this to some other value (e.g. long.MaxValue). By default it is set to 64 KB.
Enable Streaming
By default the mode of transmission for WCF is buffered. While sending and receiving all data need to be present in memory - which would not be possible for large files.
Hence you will have to change the mode to "streaming" as shown below:
<system.serviceModel>
…
<bindings>
<basicHttpBinding>
<binding name="ExampleBinding" transferMode="Streaming"/>
</basicHttpBinding>
</bindings>
…
<system.serviceModel>
Refer the documentation.
I need to create WCF client to connect service available via https.
Current client configuration responsible for WCF looks like this:
<wsHttpBinding>
<binding name="TestBinding">
<security mode="Transport">
<transport clientCredentialType="None" />
</security>
</binding>
</wsHttpBinding>
<client>
<endpoint address="https://address/etc" binding="wsHttpBinding" bindingConfiguration="TestBinding" contract="TestService.Test" name="TestName"/>
</client>
Unfortunately I'm getting an error:

I don't have an access to modify anywise this service
UPDATE:
For testing purpose I'm ignoring certificates in global.asax in Application_Start but I'm stil getting the same exception
protected void Application_Start(object sender, EventArgs e) {
ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };
}
an Untrusted certificate can cause this.
try this before calling your service:
protected void BypassCertificateError()
{
ServicePointManager.ServerCertificateValidationCallback = delegate (object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { return true; };
}
but be aware that this is not a good practice as it completely ignores the server certificate.
I've written a WCF App with the following config in the the app.config:
<system.serviceModel>
<services>
<service name="ProxyService">
<endpoint address="net.pipe://localhost/ProxyService" binding="netNamedPipeBinding" bindingConfiguration="" name="ServiceProxy" contract="IProxyService"/>
</service>
<service name="PublishSubscribeService">
<endpoint address="net.tcp://localhost/PublishSubscribeService" binding="netTcpBinding" bindingConfiguration="" name="PublishSubscribeServer" contract="IPublishSubscribeService"/>
</service>
</services>
</system.serviceModel>
And I'm having an issue with the netTcp Binding rejecting request (I've included the other service just in case it might have an effect but I don't think it does). I'm instantiating it using the following code:
private ServiceHost incomingPipeHost;
private ServiceHost incomingSubscribeHost;
incomingPipeHost = new ServiceHost(typeof(ProxyService));
incomingPipeHost.Open();
incomingSubscribeHost = new ServiceHost(typeof(PublishSubscribeService));
incomingSubscribeHost.Open();
This all works fine when I try to connect to the net.tcp service from a client running locally, and I have had this running fine on a customer site for well over a year. However, I'm now at a different customer site and when I try to connect from a remote machine I get the following exception:
System.ServiceModel.Security.SecurityNegotiationException: The server has rejected the client credentials. ---> System.Security.Authentication.InvalidCredentialException: The server has rejected the client credentials. ---> System.ComponentModel.Win32Exception: The logon attempt failed

I've tried adding the following snippet to the system.ServiceModel to disable authentication and I still get the same error:
<bindings>
<netTcpBinding>
<binding name="netTcpBindingConfig" transferMode="Buffered" maxReceivedMessageSize="5242880">
<readerQuotas maxArrayLength="5242880" />
<security mode="None" />
</binding>
</netTcpBinding>
</bindings>
What am I doing wrong? and what can I do to try and either disable authentication (which is not a requirement) or get authentication working?
You need to tell the EndPoint with the netTcpBinding to use the correct configuration (netTcpBindingConfig):
<service name="PublishSubscribeService">
<endpoint ... bindingConfiguration="netTcpBindingConfig" ... />
</service>
I try to load magento web service from https://myclient.com/api/v2_soap/index/wsdl/1 into my .net console testing application. I added service reference and it generated basichttpbinding in the app.config file with the endpoint.
however when i tried to login, i got this error: "SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://myclient.com/index.php/api/v2_soap/index/wsdl/1/' : Start tag expected, '<' not found"
Any ideas?

By this phrase of the error "Start tag expected, '<' not found", the basic problem must be the missing of the XML Start tag in probably the Magento file "wsdl.xml".
I practically don't know the easiest solution, but you can definitely go through each line manually after you have loaded the WSDL in your browser successfully. Based on the line of the error, you will have to identify the Magento module, and then rectify this defect.
Hope it helps.
it turned out to be the web host added extra layer of SSL which most of machine doesn't have it installed. that's when browser can browse it but not VS.

I figured it out, with the help of another post, which I can't find now.
I used the svcutil utility to create the service/data contracts and provide a client. Then set the binding as follows.
<basicHttpBinding>
<binding name="SsrsSoapBinding" >
<security mode="TransportCredentialOnly">
<transport clientCredentialType="Ntlm" proxyCredentialType="Ntlm" realm=""/>
<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
