WCF web service not working after deployed - wcf

I am trying to create a WCF web service which will allow other applications to retrieve a string by making a http request to this service url. I tried publishing the service in IIS and when attempting to browse to it, using the url, it says it
' The resource cannot be found'
when I checked the path to the folder I used the url,
and I get the error
'No protocol binding matches the given address
'http://localhost:xxxx/WcfSampleLibrary/Service1/mex.'
Protocol bindings are configured at the Site level in IIS or WAS configuration'
Here is the directory path of the published folder:
C:\inetpub\wwwroot\WcfServices\WcfSampleLibrary\WcfSampleLibrary.Service1
C:\inetpub\wwwroot\WcfServices\WcfSampleLibrary\Web.config
C:\inetpub\wwwroot\WcfServices\WcfSampleLibrary\bin\WcfSampleLibrary.dll
The web config file:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.web>
<compilation debug="true" />
</system.web>
<system.serviceModel>
<services>
<service name="WcfSampleLibrary.Service1" behaviorConfiguration ="mex">
<host>
<baseAddresses>
<add baseAddress = "http://192.xxx.x.xxx/WcfSampleLibrary/Service1/" />
</baseAddresses>
</host>
<!-- Service Endpoints -->
<endpoint address =""
binding="wsHttpBinding" contract="WcfSampleLibrary.IService1">
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
<!-- Metadata Endpoints -->
<endpoint address="http://localhost:xxxx/WcfSampleLibrary/Service1/mex" name="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="mex">
<serviceMetadata httpGetEnabled="false"/>
<!-- To receive exception details in faults for debugging purposes,

<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>

In IIS-hosted WCF services you don't specify a full URI in the address. IIS decides the address. Also the baseAddresses element is completely ignored when hosting in IIS (so remove it from you Web.config). The service's base address is determined by the web site & virtual directory into which your wcf service is placed.Do something like this:
<endpoint
address="mex"
binding="mexHttpBinding"
contract="IMetadataExchange"
/>
Then your address would be http://IIS.SERVER/SiteName/Folder/WcfSampleLibrary.Service1.svc. If you're not sure what the address is, use your IIS Administration tool, select the site that has the service in it, Right-click and choose Advanced -> Browse Site.
Also, I'd turn on httpGetEnabled on your mex behavior--if you want to publish your WSDL. This makes it easier to consume your service as you are developing it:
<behaviors>
<serviceBehaviors>
<behavior name="mex" >
<serviceMetadata httpGetEnabled="true" />
</behavior>
</serviceBehaviors>
</behaviors>
With httpGetEnabled being on, browsing to your service URI will give you an option to see the WSDL.

WCF service metadata (wsdl) cannot be accessed: error 400

I have a problem with WCF metadata on a new installation ( IIS 10 on Windows Server 2016)
Situation
WCF service running fine (as it used to do on previous installation)
Navigation (via browser) of wsdl is NO more possible, or better
http://ServiceA/ServiceA.svc: yes (web page available) but link to xml not working (error 400 from IIS)
https://ServiceA/ServiceA.svc: not even the page
Moreover in the serviceMetadata it is stated to use https no http, that is in contrast with the behaviour just described.
Below an extract of web.config
<services>
<service behaviorConfiguration="ServiceBehavior" name="...">
<endpoint address="https://<fqdn>/ServiceA/ServiceA.svc"
binding="wsHttpBinding"
bindingConfiguration="wsHttpEndpointBinding"
name="WsHttpBinding"
contract="ServiceContracts.IServiceA">
</endpoint>
</service>
</services>
<behaviors>
<serviceBehaviors>
<serviceMetadata httpsGetEnabled="true" httpGetEnabled="false" />
...
Could it be something linked to name resolution?
The PC name is AAAAAA, the FQDN is BBBBB.domain.ext
Thanks for any suggestion

The WCF service deployed in IIS does not need to set the endpoint address in web.config.
Here is my demo:

This is web.config. This project is a template project.
The base address of the WCF service in IIS is as follows:

WCF Service Hosted on IIS10. Can browse the .svc file but the wsdl does not show up

I have a test WCF service that I hosted on IIS. I added a new application to the default website and used default app pool to host my test service. I am able to browse the .svc file from the content view in IIS and the success page along with a link to wsdl opens up on Windows IE. However, on clicking the wsdl link, a HTTP 404(Not found) error is thrown.(everything is on my localhost being accessed internally)
I have added the metadata endpoint and this is the relevant portion of my web.config file.
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="mexBehaviour">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service behaviorConfiguration="mexBehaviour" name="ClassLibrary1.HelloWorldService">
<endpoint address="HelloService" binding="basicHttpBinding" bindingConfiguration=""
contract="ClassLibrary1.IHelloWorldService" />
<endpoint address="mex"
binding="mexHttpBinding"
contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="http://localhost:17000"/>
</baseAddresses>
</host>
</service>
</services>
</system.serviceModel>
Can someone please guide me about what I can be missing? Could it be a permissions issue or anything else?
Thanks.
There is no need to add the base address to service contract which will be provided by the IIS web server.
The default wcf application configuration enable the service metadata and we are able to access the metadata by the svc page or we directly use the following url.
http://localhost:90/Service1.svc?wsdl
Feel free to contract me If the problem still exists.

How To Change The Binding of a WCF Service

I have a very simple (see any getting started sample online) wcf service library. And i can run it via the WCF Test Client exe on localhost. But when accessing it via another client tool, like soapUI, i get errors. I believe the errors are related to security configuration of the service.
How can i change the binding of a service, like is suggested in this post:
"Invalid or expired security context token" when running after a debugging restart
Is this in app.config or web.config. my project doesnt even have a web.config.

What is wrong with my WCF Meta Data Configuration?

This is a follow on from this question I've configured the a WCF service running in IIS (From within Visual Studio 2010) to run one Web service and one net.tcp service. After a lot of hacking I've managed to get the Web Service to load into the WCF test client, but I can't get the Net.Tcp service to load into the test client.

When I run the Visual Studio Debugger to publish the Service I can access the web service by entering the following url into the WCF Test Application:
http://localhost:8523/MyWebService.svc
But if I enter the following Url into the WCF Test Application I get an error:
net.tcp://localhost:8523/ServerService.svc
Here is the Error I see:
Error: Cannot obtain Metadata from
net.tcp://localhost:8523/ServerService.svc If this is a Windows (R)
Communication Foundation service to which you have access, please
check that you have enabled metadata publishing at the specified

MSDN documentation at
http://go.microsoft.com/fwlink/?LinkId=65455.WS-Metadata Exchange
Error URI: net.tcp://localhost:8523/ServerService.svc Metadata
contains a reference that cannot be resolved:
'net.tcp://localhost:8523/ServerService.svc'. You have tried to
create a channel to a service that does not support .Net Framing. It
is possible that you are encountering an HTTP endpoint. Expected
record type 'PreambleAck', found '72'.
Having read this question is it possible that the webserver in VS 2010 doesn't support net.tcp binding?
It looks like the issue I was seeing was that the Web Server in Visual Studio 2010 doesn't support Net.Tcp Binding.
I've got slightly further by installing IIS7 (IIS6 doesn't support Net.Tcp either) and telling visual studio to use IIS instead.
You can do this by going to the properties page of your service and selecting the "Web Tab" select the Use Local IIS Web Server radio Button and configure the webserver.
You can also tell is to start an external program on this tab to make it start the WcfTestClient.exe and pass in the URL to your services as command line parameters.
I'm still having issues but they are different issues so I'll open another question.
