Hosting WCF on IIS

I have problem with hosting WCF Application service on IIS. The service is working inside solution with other project by Add Service Reference, but when i want host it on IIS I get error when I open Service.svc from IIS.
Could not load type 'System.ServiceModel.Activation.HttpModule' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

What can be the problem ?

It could be that you have multiple versions of the .NET Framework installed on the server. See https://msdn.microsoft.com/en-us/library/hh169179(v=nav.90).aspx and https://support.microsoft.com/en-us/kb/2015129

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.

Error in wcf service

I am using a wcf service to provide some data to my clients to plot a graph .I have seen some thing and created the service But when I run it is showing following error.How to over come it?
The type 'WcfService2.Servi', provided as the Service attribute value in theServiceHostdirective, or provided in the configuration elementsystem.serviceModel/serviceHostingEnvironment/serviceActivationscould not be found.
this is my web.config file

Your service contract type is called WcfService2.Servi. This looks like a typo. If you correct this, does the service work?

hosting Wcf service via ServerHost in IIS，Console or winform App can add reference?

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>
