WCF net.tcp connection always fails - wcf

I tried to setup a service for testing using a net.tcp binding. I also set a http endpoint. The configuration is as follows:
<system.serviceModel>
<behaviors>
<endpointBehaviors>
<behavior name="Inbound_REST">
<webHttp />
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior name="InboundHttpConfiguration">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
<behavior name="InboundTcpConfiguration">
<serviceMetadata httpGetEnabled="false" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service behaviorConfiguration="InboundTcpConfiguration" name="Inbound">
<endpoint address="" binding="netTcpBinding" contract="IContract">
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
<host>
<baseAddresses>
<add baseAddress="net.tcp://localhost:6969/Inbound" />
</baseAddresses>
</host>
</service>
</services>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
<client>
<endpoint name="httpEndPoint" address="http://localhost:1568/Inbound.svc" binding="basicHttpBinding" contract="IContract" />
<endpoint name="tcpEndPoint" address="net.tcp://localhost:6969/Inbound" binding="netTcpBinding" contract="IContract" />
</client>
<bindings>
<basicHttpBinding>
<binding name="httpbind">
<security mode="Transport">
<transport clientCredentialType="None"/>
</security>
</binding>
</basicHttpBinding>
<netTcpBinding>
<binding name="tcpbind">
<security mode="Transport">
<transport clientCredentialType="None" />
</security>
</binding>
</netTcpBinding>
</bindings>
</system.serviceModel>
When I attempt to consume the service using the net.tcp binding, it always return me the error:
Could not connect to net.tcp://localhost:6969/Inbound. The connection attempt lasted for a time span of 00:00:00.9531494. TCP error code 10061: No connection could be made because the target machine actively refused it 127.0.0.1:6969.
By the way, the http binding works fine. I think it could be some machine configuration, but wasn't able to find what's the root cause.

If you are trying to run your WCF service through visual studio netTcpBinding is not supported. Sorry!
Check out this post for a more detailed explanation.

Why did you leave out the ".svc" for the net.tcp address for the client? Maybe it should be "net.tcp://localhost:6969/Inbound.svc"

What hosting you are using..IIS7 or console or others?
1)Check all tcp services are running in services.msc
2)Turn off your fire wall or add firewall exception to your tcp port
if you are hosting in iis7 check this link
IIS7 support for non http protocols

WCF SSL Service giving 404 not found

I keep getting a 404 error for my WCF service over SSL. Without SSL it works fine. I can access the service directly in the browser and set a web reference to it fine. In Fiddler it gives an "There was no channel actively listening at end point" error and here is the web.config:
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="ServiceBehavior">
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="Inventory.Product.ProductDataAspNetAjaxBehavior">
<enableWebScript />
</behavior>
</endpointBehaviors>
</behaviors>
<bindings>
<webHttpBinding>
<binding name="secureHttpBinding">
<security mode="Transport">
<transport clientCredentialType="None"/>
</security>
</binding>
</webHttpBinding>
</bindings>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
<services>
<service name="Inventory.Product.ProductData"
behaviorConfiguration="ServiceBehavior">
<endpoint address="" binding="webHttpBinding"

contract="Inventory.Product.ProductData" />
<endpoint contract="IMetadataExchange" binding="mexHttpBinding"
address="mex" />
</service>
</services>
</system.serviceModel>
Ok, I found the answer at WCF over SSL - 404 error. I had forgot to set the binding configuration - when I did that, it worked.

Unable to add service reference

I am unable to connect to a WCF service hosted on our dev server but I am able to browse to it.
I am just trying to add a service reference via Visual Studio and when I click on Go, it gives me the following error.
An error occurred while receiving the HTTP response to http://...Service.svc. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.
My other colleagues are able to add the service reference and connect to this service with no issues, which makes it harder for me to understand the cause of this issue.

WCF service self hosting with https

Currenlty there is a Wcf service hosted as windows service in one of our client side machine, actually currently this is working with normal http call. As we need to use https instead of http, for that we modified app.config but after starting the service the https url not working.Then we tried URL reservation by using netsh http add urlacl url=https://+:18732/Peripheral/ user=Everyone.Then we restared the service again it's not able to access the https url.
we are getting the error in the URl browser •Make sure that TLS and SSL protocols are enabled.
Is this related to any certificate issue? if so how we can able to solve this issue?
The web.config is provied below:-
<system.serviceModel>
<standardEndpoints />
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>
<bindings>
<basicHttpBinding>
<binding name ="soapBinding">
<security mode="Transport">
<transport clientCredentialType="None"/>
</security>
</binding>
</basicHttpBinding>

<binding name="Bind1" crossDomainScriptAccessEnabled="true">

</security>
</binding>
</webHttpBinding>
</bindings>

<endpoint address="https://localhost:18732/Peripheral/" binding="webHttpBinding" behaviorConfiguration="EndPBhvr" bindingConfiguration="Bind1"
contract="Peripheral.Server.Contract.IPeripheralService">
<!--<identity>
<dns value="localhost" />
</identity>-->
</endpoint>
<endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange" />
</service>
</services>

<serviceMetadata httpsGetEnabled="true" httpGetEnabled="false" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
Anyone knows how to fix this and what we needed to do so that we could able to access the url as https from windows services?
You may need also to bind ssl certificate to the specific port number using netsh or HttpConfig tool depending from OS version. Detailed instructions can be found here
In your case it could be:
netsh http add sslcert ipport=0.0.0.0:18732 certhash=<certhash> appid={<guid>} clientcertnegotiation=enable
where
certhash = your certificate Thumbprint(X509Certificate2.Thumbprint)
appid = could be just Guid.NewId()

Accessing WCF service on AppHarbor via https

I'm trying to secure my WCF service using transport security model. I've successfully deployed my service to AppHarbor. But I'm getting the following exception when I try to access service page:
[InvalidOperationException: Could not find a base address that matches scheme https for the endpoint with binding BasicHttpBinding. Registered base address schemes are [http].] ...
I haven't uploaded any certificates, just using piggyback SSL there. I've downloaded the build and deployed it on my machine. It works fine.
Here is my system.serviceModel section of web.config:
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="TransportSecurity">
<security mode="Transport">
<transport clientCredentialType="None"/>
</security>
</binding>
</basicHttpBinding>
</bindings>
<services>
<service behaviorConfiguration="AuthService.AuthServiceBehavior" name="AuthService.AuthService">
<host>
<baseAddresses>
<add baseAddress="https://auth.apphb.com/AuthService.svc" />
</baseAddresses>
</host>
<endpoint address="" binding="basicHttpBinding" bindingConfiguration="TransportSecurity" contract="AuthService.IAuthService" />
<endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange" />

I've already tried this Hosting a WCF Web API app on AppHarbor?
Can somebody please explain me what I'm doing wrong?
This issue frequently appear when you communicate with the wcf web service thru the LB (AppHarbor one of the example of it).
You should know several things about such kind of communications.
1) Communication between yours client application and LB is secured (https is in use). So you should leverage security binding on the client side.
<basicHttpBinding>
<binding name="BasicHttpBinding_IAuthService">
<security mode="Transport">
<transport clientCredentialType="None" />
</security>
</binding>
</basicHttpBinding>
2) Communication between LB and web-front uses http, so server binding should be basicHttpBinding without extra configuration.
<endpoint binding="basicHttpBinding" contract="AuthService.IAuthService" />
Summarizing all that stuff we have
Client
<configuration>
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IAuthService">
<security mode="Transport">
<transport clientCredentialType="None" />
</security>
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="https://auth.apphb.com/AuthService.svc"
binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IAuthService"
contract="AuthService.IAuthService" name="BasicHttpBinding_IAuthService" />
</client>
</system.serviceModel>
</configuration>
Server
<system.serviceModel>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />

Your approach is not going to work right off the bat. This is because SSL is terminated at the load balancers and the app servers see http traffic. You can read more about AppHarbor load balancers here.
You might be able to fool WCF with this module.
There are also some hints in this discussion: http://support.appharbor.com/discussions/problems/829-transportwithmessagecredential-https-ssl

Both http and https for one service

I'm tackling with an issue but couldn't sort out it.
I have one service which is worked inside asp.net 4.0 app.
The site is available both over http and https.
Issue is that the service with below provided config snipped can work either over http or over https.
What is wrong in my config?
<system.serviceModel>
<bindings>
<webHttpBinding>
<binding name="webHttpsBinding">
<security mode="Transport">
<transport clientCredentialType="None"/>
</security>
</binding>
</webHttpBinding>
</bindings>
<behaviors>
<endpointBehaviors>
<behavior name="HMS.DataServices.PaymentsServiceBehavior">
<enableWebScript />
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior name="HMS.DataServices.PaymentsServiceBehavior">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service name="HMS.DataServices.PaymentsService">
<!--HTTP-->
<endpoint address="" binding="webHttpBinding" contract="HMS.DataServices.IPaymentsService"
behaviorConfiguration="HMS.DataServices.PaymentsServiceBehavior" />
<!--HTTPS-->
<endpoint address="" binding="webHttpBinding" bindingConfiguration="webHttpsBinding"
contract="HMS.DataServices.IPaymentsService" behaviorConfiguration="HMS.DataServices.PaymentsServiceBehavior" />
</service>
</services>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
</system.serviceModel>
this config works over https but not nttp
In the windows log I see next error
The exception message is: Could not find a base address that matches scheme https for the endpoint with binding WebHttpBinding. Registered base address schemes are [http]..
Thanks in advance!
