C# error wcf services

I am trying to deploy an WCF, using Internet Information Service. I worked with visual studio 2015. But i got this error:
Configuration binding extension 'system.serviceModel/bindings/true'
could not be found. Verify that this binding extension is properly
registered in system.serviceModel/extensions/bindingExtensions and
that it is spelled correctly.
My Web.config is the following:

Thanks for help!!

hosting WCF in IIS ignores endpoints

When hosting WCF service on IIS using svc, the endpoints are ignored and only a default one is created.
Why is that and how to I make the endpoints work?
My setup:
service.svc
<%#ServiceHost language=c# Debug="true" Service="ComputerStudyService.SectionHandlerService"%>
web.config
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0"/>
</system.web>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="MyServiceTypeBehaviors">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service name="ComputerStudyService.SectionHandlerService" behaviorConfiguration="MyServiceTypeBehaviors">
<endpoint address="/" binding="wsHttpBinding" contract="ServicesLibrary.ISectionHandlerService"/>
<endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="/mex"/>
</service>
</services>
</system.serviceModel>
</configuration>
When I navigate to http://localhost:24906/service.svc
I get the message telling me I created a service and I can go http://localhost:24906/service.svc?wsdl to get the meta.
However the metadata doesn't give me any of my endpoints!
<wsdl:service name="SectionHandlerService">
<wsdl:port name="WSHttpBinding_ISectionHandlerService" binding="tns:WSHttpBinding_ISectionHandlerService">
<soap12:address location="http://localhost:24906/service.svc"/>
<wsa10:EndpointReference>
<wsa10:Address>http://localhost:24906/service.svc</wsa10:Address>
<Identity xmlns="http://schemas.xmlsoap.org/ws/2006/02/addressingidentity">
<Upn>Roi-PC\Roi</Upn>
</Identity>
</wsa10:EndpointReference>
</wsdl:port>
</wsdl:service>
Any help would be much appreciated.

NetTcp AND HTTP binding in WCF

I've been fiddling for two days now, trying to get my TCP endpoint working in my Wcf application.
I've hosted my Wcf app in IIS8 (NOT IIS Express), configured the website to enable net.tcp protocol listening on port 808.
But no matter what I do, I can't reach the TCP endpoint. The HTTP endpoint is working as intended.
Here's my Web.config:
<configuration>
<appSettings>
<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
</appSettings>
<system.web>
<compilation debug="true" targetFramework="4.5" />
<httpRuntime targetFramework="4.5"/>
</system.web>
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="DefaultHttpBinding" />
</basicHttpBinding>
<netTcpBinding>
<binding name="DefaultTCPBinding" portSharingEnabled="true">
<security mode="None"/>
</binding>
</netTcpBinding>
</bindings>
<services>
<service behaviorConfiguration="SimplBehavior" name="SimplWCF.WcfService">
<endpoint address="mextcp" binding="mexTcpBinding" contract="IMetadataExchange"/>
<endpoint address="local" binding="netTcpBinding" contract="SimplWCF.IWcfService" bindingConfiguration="DefaultTCPBinding" name="localTcpBinding"/>
<!-- Used for connecting the service to CMS-->
<endpoint address="mexhttp" binding="mexHttpBinding" contract="IMetadataExchange"/>
<endpoint address="public" binding="basicHttpBinding" contract="SimplWCF.IWcfService" bindingConfiguration="DefaultHttpBinding" name="publicHttpBinding"/>
<!-- Used for connecting the webpages to the service-->
<host>
<baseAddresses>
<add baseAddress="http://localhost:50356/SimplWCF/" />
<add baseAddress="net.tcp://localhost:808/SimplWCF/"/>
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="SimplBehavior">
<!-- To avoid disclosing metadata information, set the values below to false before deployment -->
<serviceMetadata httpGetEnabled="false" httpsGetEnabled="false"/>
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
<protocolMapping>
<add binding="basicHttpsBinding" scheme="https" />
<add binding="basicHttpBinding" scheme="http"/>
<add binding="netTcpBinding" scheme="net.tcp"/>
</protocolMapping>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
<!--
To browse web app root directory during debugging, set the value below to true.
Set to false before deployment to avoid disclosing web app folder information.
-->
<directoryBrowse enabled="true"/>
</system.webServer>
</configuration>
I know that the HTTP endpoint doesn't work properly with httpGetEnabled="false", but right now I just need my TCP endpoint to work.
When I try to add a service reference in another project in Visual Studio (in the namespace as my WCF) I write the URL like this:
net.tcp://localhost:808/SimplWCF/WcfService.svc
But I'm not 100% sure this is the correct way of doing it.
Hope somebody can help me.

I finally got it working now!
I removed the relative address in the TCP endpoint, so that my config now looks like this: `
<services>
<service behaviorConfiguration="SimplBehavior" name="SimplWCF.WcfService">
<endpoint address="mextcp" binding="mexTcpBinding" contract="IMetadataExchange"/>
<endpoint address="" binding="netTcpBinding" contract="SimplWCF.IWcfService" bindingConfiguration="DefaultTCPBinding" name="localTcpBinding"/>
<!-- Used for connecting the service to CMS-->
<endpoint address="mexhttp" binding="mexHttpBinding" contract="IMetadataExchange"/>
<endpoint address="public" binding="basicHttpBinding" contract="SimplWCF.IWcfService" bindingConfiguration="DefaultHttpBinding" name="publicHttpBinding"/>
<!-- Used for connecting the webpages to the service-->
<host>
<baseAddresses>
<add baseAddress="http://localhost:50356/SimplWCF/" />
<add baseAddress="net.tcp://localhost:808/SimplWCF/"/>
</baseAddresses>
</host>
</service>
</services>
Thank you for your time!

1 web page access success by JQuery ajax
2 Metadata is also released, the URL access success;
*But why the console app add service reference will appear "object reference not set to an instance of an object"????*

Looks like something wrong with metadata of your WCF service.
Check operations contracts definition.
Do not you have conflicting contract names?
Try to use ServiceModel Metadata Utility Tool (Svcutil.exe) to generated client code from WSDL instead of Visual Studio tool

I couldn't properly publish duplex wcf service

I am trying to publish my duplex wcf service on a server with no success, I am able to publish it on local IIS, but when I publish it to server its address become net.tcp://win-rhkt30stjd7/Broadcastor/BroadcasterService.svc. As you would agree such address is not useful at all while creating the service reference on client. I tried to publish it as WCF application project, and service library project but both is giving the same result. Probably something is missing from my Web.config file but I don't know what it is. Please help me out here. Below is my Web.config file:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<appSettings>
<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
</appSettings>
<system.web>

I dont see any address part in your NET TCP endpoint
1 : Add a base address as below :
<host>
<baseAddresses>
<add baseAddress="net.tcp://localhost:8088" />
</baseAddresses>
</host>
2 : add an address parameter to your net tcp endpoint as :
<endpoint address = "tcpEndPoint"
binding="netTcpBinding"
contract="BroadcastorServiceApp.IBroadcastorService"></endpoint>
3 : Alse give a behavior name as :
<serviceBehaviors>
<behavior name="ServiceBehavior">
<serviceMetadata httpGetEnabled="True" httpsGetEnabled="True" />
<serviceDebug includeExceptionDetailInFaults="True" />
</behavior>
</serviceBehaviors>
And add it to the service like :
<service name="BroadcastorServiceApp.BroadcastorService" behaviorConfiguration="ServiceBehavior">
<endpoint binding="netTcpBinding" contract="BroadcastorServiceApp.IBroadcastorService"></endpoint>
<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" />
</service>
