IIS 7.5 / WCF - net.tcp status unknown - c#

I'm trying to get my WCF service working with netTcpBinding instead of wsHttpBinding, but I can't seem to get it working.
I added the net.tcp binding to IIS7.5 but the status is Unknown (and when I also remove the http binding it puts a big red X through the site and I have to add a new http binding before I can access any settings again). I already looked here and on Google but I could only find two or three posts about this issue without any true solutions.
What I have:
WAS service running, and also the Net.* services.
Added net.tcp in Advanced Settings in IIS.
WCF non-http is installed.
There seems to be a TCP listener running, as it shows in netstat that it is listening on my specified port: 809) and I also got firewall message (also tried disabling the firewall/antivirus, but it didn't help).
WCF Test Client results in this error:
Error: Cannot obtain Metadata from net.tcp://localhost:809/MyService.svc
My Web.config (as copied mostly from MSDN, for proper layout look here http://pastebin.com/Ru8p0T9N):
<services>
<service behaviorConfiguration="MyBehavior" name="WCFService.MyService">
<endpoint address="" binding="netTcpBinding" bindingConfiguration="Binding1" name="MyServiceEndpoint" contract="WCFService.MyService">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexTcpBinding" bindingConfiguration="" name="MyServiceMexTcpBidingEndpoint" contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="net.tcp://localhost:809/MyService.svc" />
</baseAddresses>
</host>
</service>
</services>
<behavior name="MyBehavior">
<serviceMetadata httpGetEnabled="false" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
<netTcpBinding>
<binding name="Binding1"hostNameComparisonMode="StrongWildcard"sendTimeout="00:10:00"maxReceivedMessageSize="65536"transferMode="Buffered"portSharingEnabled="true">
<security mode="Message">
<transport clientCredentialType="None" />
<message clientCredentialType="None" />
</security>
</binding>
</netTcpBinding>
Everything works fine with wsHttpBinding but not with net.tcp. I tried several different settings in the Web.config from multiple sources but I keep ending up with the same problem.

Did you add net.tcp as an Enabled Protocol in IIS? Manage website => advanced settings => enabled protocols (comma delimited)

For people having the same problem: As I said before, I changed the Application Pool to Classic and it didn't work (http also didn't work anymore), but when I changed it back and recycled application pool it suddenly worked.

Custom Binding WCF with tcpTransport

I have a WCF Service hosted on a Windows Service that runs on the same network using its own credentials. Security is not important. However, speed and reliability are important.
So, I tried with a netTcpBinding binding. However, I noticed that when I reference the Service into the client. It adds to the configuration file the identity tag with the information of the account that the service is running on:
<identity>
<userPrincipalName value="account#domain" />
</identity>
I really don't want to have this in the client's configuration file, nor I want to pass it programmatically.
When I use instead a basicHttpBinding, I noticed that it does not add this tag. However, I still want to stick with net.tcp. So, my next try was to use a customBinding
So, here is where my problem is. I am not able to reference the custom binding to the client. Can someone verify my configuration? Also. Will this be enough to ignore completely the identity tag? If this is not the proper way, what would be the proper way? Thanks
<system.serviceModel>
<services>
<service name="LicenseServiceLogic.LicenseService">
<endpoint address="net.tcp://localhost:8000/LicenseService"
binding="myCustomBinding"
contract="LicenseServiceLogic.ILicenseService">
</endpoint>
</service>
</services>
<bindings>
<customBinding>
<binding name="myCustomBinding">
<compactMessageEncoding>
<binaryMessageEncoding/>
</compactMessageEncoding>
<tcpTransport listenBacklog ="100"
maxBufferPoolSize ="524288"
maxBufferSize ="2147483647"
maxReceivedMessageSize ="2147483647"/>
</binding>
</customBinding>
</bindings>
<client>
<endpoint binding="customBinding"
bindingConfiguration="myCustomBinding"
contract="IMetadataExchange"
name="http" />
</client>
</system.serviceModel>
First, the reason that we could not reference the custom binding to the client is we should add MEX service endpoint and enable the service metadata behavior. Like below,
<system.serviceModel>
<services>
<service name="VM1.MyService" behaviorConfiguration="mybehavior">
<endpoint address="" binding="netTcpBinding" contract="VM1.IService" bindingConfiguration="mybinding">
</endpoint>
<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" ></endpoint>
<host>
<baseAddresses>
<add baseAddress="net.tcp://localhost:5566"/>
</baseAddresses>
</host>
</service>
</services>
<bindings>
<netTcpBinding>
<binding name="mybinding">
<security mode="None"></security>
</binding>
</netTcpBinding>
</bindings>
<behaviors>
<serviceBehaviors>
<behavior name="mybehavior">
<serviceMetadata />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
Besides, if we don’t want to add the identity tag to the client configuration, just we need to do is to set the Security Mode to NONE. As shown above.

WebHttpBinding with Http and Https

I am trying to use https & http for the website. The website has .svc files which act as REST service and called from JavaScript.

Browsing https://myserver/services/Lookups.svc/Hello gives
Could not find a base address that matches scheme http for the endpoint with binding WebHttpBinding. Registered base address schemes are [https]
Browsing http://myserver/services/Lookups.svc/Hello gives
Could not find a base address that matches scheme https for the endpoint with binding WebHttpBinding. Registered base address schemes are [http]
If I remove any one endpoint it works. Example removing endpoint configured with bindingConfiguration="httpWebBinding" works for HTTPS ,
How can I make it work with HTTP and HTTPS? As of now, I can able to use either http or https by removing one endpoint.
Referred How can I combine the WCF services config for both http and https in one web.config? and How do you setup HTTP and HTTPS WCF 4 RESTful services?
Note: In IIS, it is two web sites one listen on http and another on
https. Both sharing same code in physical folder
UPDATE: As of now, I removed endpoints and it works. But my concern is removing endpoing configured with behaviourConfiguration doesnt look great solution to me.
This works for both http & https
<services>
<service behaviorConfiguration="MyServiceBehaviour" name="MyService.Lookups">

I've recreated your scenario and used your web.config to configure endpoints for my test service. Your configuration is ok and works correctly. The part that don't works for you is probably your https configuration in IIS. Make sure you have enabled https access to your service. If you test it with IISExpress from Visual Studio then left click on your project and in the properties window (View -> Properties Window ) select for SSL Enabled = True.
As #Lesmian pointed out in his answer, the issue is in your IIS configuration.
More specifically in:
Note: In IIS, it is two web sites one listen on http and another on https. Both sharing same code in physical folder
The reason is that IIS can not handle endpoints on a schema which it does not support.
You have two sites, and one of them has HTTP binding but does not has HTTPS, and the other has HTTPS but not HTTP.
So when you browse to http:// URL, IIS directs you to the (surprise!) http-enabled site, reads web.config, sees that it registers https endpoint (which is not supported by the site) and throws the exception telling that there is no https scheme support on the http-enabled-only site.
When you browse to the https:// URL the situation is similar - IIS does not allow you to use http endpoint on the https-enabled-only site.
To handle the issue you better use a single site with two bindings.
Another (and more complex) option would be using different web.configs for sites: set up separate sites (pointed to separate folders) and use the publishing and web.config transforming tools of the Visual Studio
Add This Code.
<protocolMapping>
<add scheme="http" binding="webHttpBinding" bindingConfiguration="httpWebBinding"/>
<add scheme="https" binding="webHttpBinding" bindingConfiguration="httpsWebBinding"/>
</protocolMapping>
I dont't know this query is still active or not but as i checked Please
Add binding="mexHttpsBinding" also
with binding="mexHttpBinding" with different endpoint
This helps me.

Can I use netTcpBinding for WCF services hosted outside of IIS?

My WCF service is being hosted as a Windows managed service, so I'm unsure of whether or not I can still use the netTcpBinding. I've tried following a couple of guides at MSDN, but for some reason my service always fails to start whenever I do the switch from basicHttpBinding. Perhaps there are additional steps that services outside of the IIS are required to undergo?
Yes you can host WCF service with netTcpBinding outside of IIS, in Windows service or even Console Application if you want to.
Here is config file sample:
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="ServiceBehavior">
<serviceMetadata />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service behaviorConfiguration="ServiceBehavior"
name="XX.XX.Service">
<endpoint address=""
binding="netTcpBinding"
bindingConfiguration="BindingConfiguration"
contract="XX.XX..IService" />
<endpoint address="mex"
binding="mexTcpBinding"
contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="net.tcp://localhost:8731/XXService" />
</baseAddresses>
</host>
</service>
</services>
<bindings>
<netTcpBinding>
<binding
name="BindingConfiguration">
<security mode="None" />
</binding>
</netTcpBinding>
</bindings>
</system.serviceModel>
[Edit]
Problems with your config file:
base address is http instead of net.tcp
metadata endpoint is mexHttpBinding instead of metTcpBinding
security - by default windows authorization will be used, if test communication between to boxes, you might have permission problem. I suggest to start with security mode None and then adjust security when everything else works.
you don't need to specify httpGetEnabled for service behavior
if the port that you are going to use is already in use, you will not be able to start service
You absolutely can, and I'd go so far as to say you should.
Here's your problem:
<services>
<service name="Server.FileService" ...
<host>
<baseAddresses>
<add baseAddress="http://localhost:8000/Test/file"/>
</baseAddresses>
</host>
<endpoint address="" binding="netTcpBinding" contract="Server.IFile" />
<endpoint address="mex" binding="mexHttpBinding" ...
The net.tcp address must have a net.tcp:// prefix, not a http:// prefix.
I don't normally use baseAddress so can't give advice on that. I'd remove baseAddress and instead use
<endpoint address="net.tcp://localhost:8001/Test/file" ..
(note that I would also choose another port over 8000)

edit: I am self-hosting in a Windows Service; I am not using IIS.
do you mean that a WCF client throws this error ?
if so:
please run the follwing at the command prompt:
netstat -ona | find "8001"
if this returns data, please post it
You need to add TCP support to your IIS.
To enable TCP, MSMQ, or named pipes communication specifically, perform the additional step of configuring support for the associated protocol. For TCP communication, bind the default Web site to a net.tcp port by using the Appcmd command-line utility. Appcmd is an IIS utility that enables you to administer virtual sites, directories,applications, and application pools.
%windir%\system32\inetsrv\appcmd.exe set site "Default Web Site" -
+bindings.[protocol='net.tcp',bindingInformation='808:*']
To support the other protocols, run additional commands that enable those protocols for the default Web site. At this point, you have configured the net.tcp protocol at the site level.
%windir%\system32\inetsrv\appcmd.exe set app "Default Web Site/OrderServiceHost"
/enabledProtocols:http,net.tcp

WCF security authentication

I have a simple service and I try to set up authentication. On the client I want the user to enter their Windows user account. And the WCF will use the username/password provided by the client and authenticate them against Windows authentication.
Here is my server app.config
<system.serviceModel>
<services>
<service name="WcfService.Service1" behaviorConfiguration="WcfService.Service1Behavior">
<host>
<baseAddresses>
<add baseAddress = "http://localhost:8731/Design_Time_Addresses/WcfService/Service1/" />
</baseAddresses>
</host>
<endpoint address ="" binding="wsHttpBinding" contract="WcfService.IService1">
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="WcfService.Service1Behavior">
<serviceMetadata httpGetEnabled="True"/>
<serviceDebug includeExceptionDetailInFaults="True" />
<serviceCredentials>
<userNameAuthentication userNamePasswordValidationMode = "Windows"/>
</serviceCredentials>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
Here is my client app.config
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="WSHttpBinding_IService1">
<security mode = "Message">
<message clientCredentialType = "UserName"/>
</security>
</binding>
</wsHttpBinding>
</bindings>
<client>
<endpoint address="http://localhost:8731/Design_Time_Addresses/WcfService/Service1/"
binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IService1"
contract="ServiceReference1.IService1" name="WSHttpBinding_IService1">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
</client>
</system.serviceModel>
Here is my code on the client
ServiceReference1.Service1Client client = new WcfAuthentication.ServiceReference1.Service1Client();
client.ClientCredentials.UserName.UserName = "mywindowsusername";
client.ClientCredentials.UserName.Password = "mywindowsuserpassword";
Console.WriteLine(client.GetData(5));
But I'm always getting this exception :
{"Secure channel cannot be opened because security negotiation with the remote endpoint has failed. This may be due to absent or incorrectly specified EndpointIdentity in the EndpointAddress used to create the channel. Please verify the EndpointIdentity specified or implied by the EndpointAddress correctly identifies the remote endpoint. "}
{"The request for security token has invalid or malformed elements."}
It looks like you generated the service and client configuration separately (by hand). It usually is a good idea to generate the client configuration from the service using svcutil or Visual Studio's 'Add Service Reference'. This way you know that you get the client config that corresponds to the service config.
What you want is possible, but WCF doesn't allow you to transmit your username/password token in plain text when using wsHttpBinding. This means that you must either host your service using https or use a service certificate. Here's a post with some more details.
But I'm also wondering why you would want anything like this. It may be a better idea to use integrated Windows authentication. This is even the default setting for wsHttpBinding. This way you do not need your client(s) to enter their Windows username/password.
I think Windows Authentication with WsHttpBinding only works with https.
See this: http://msdn.microsoft.com/en-us/library/ff650619.aspx
binding.Security = new WSHttpSecurity{Mode = SecurityMode.None};
