Hide one WCF service in wsdl

I have my own wsdl with few methods.
They are visible in e.g. SoapUI.
I want to implement new service, but I want to hide it from wsdl, but I want to call it.
Is that possible?

Yes it is. Just tell WCF you do not want to expose metadata in the service configuration:
<system.serviceModel>
<services>
<service behaviorConfiguration="MyServiceBehavior" name="MyService">
<endpoint address="http://MyService:8888" binding="wsSomeBinding" contract="IMyServiceContract" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="MyServiceBehavior">
<serviceMetadata httpGetEnabled="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>

WCF Test Client EndPoint error

IN my WCF Service, the WCF Test Client reports the following error
System.InvalidOperationException: Could not find a base address that matches scheme net.tcp for the endpoint with binding NetTcpBinding. Registered base address schemes are [http].
My App.Config is this:
<?xml version="1.0" encoding="utf-8" ?>
<services>
<service name="Practicon.SAPServiceLibrary.SAPDownloadService" behaviorConfiguration="debug">
<endpoint address="net.tcp://localhost:8082/SAPDownloadService" binding="netTcpBinding" contract="Practicon.SAPServiceLibrary.ISAPDownloadService">
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
<host>
<baseAddresses>
<!--add baseAddress="http://localhost:8083/Design_Time_Addresses/Practicon/SAPServiceLibrary/SAPDownloadService/"/> -->
<add baseAddress="net.tcp://localhost:8082/SAPDownloadService"/>
</baseAddresses>

</service>
</services>

<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
<client>
<endpoint name="PracticonSAPDownloadEndPointClient"
address="net.tcp://localhost:8082/SAPDownloadService"
binding="netTcpBinding"
bindingConfiguration="BindingConfiguration"
contract="Practicon.SAPServiceLibrary.ISAPDownloadService">
<identity>
<servicePrincipalName value=""/>
</identity>
</endpoint>
</client>
<bindings>
<netTcpBinding>
<binding name="BindingConfiguration"
transferMode="Buffered"/>
</netTcpBinding>
</bindings>
I have got a net.tcp Endpoint - the Service runs fine, just that this error is reported in the WCF Hosting.
Can someone explain what I've done wrong and how to correct it?
Thanks

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?

How to configure webHttp Binding while creating a WCF service in Azure?

I am developing a WCF WebRole service in Azure and need to invoke a method that to give employee data in JSON format.But unlike a normal WCF Web Service, I dont know how to configure the "Web.config" for WCF Webrole and my code "Web.config" for normal WCF service is below:
<system.serviceModel>
<services>
<service name="empl.Service1" behaviorConfiguration="empl.Service1Behavior">
<!-- Service Endpoints -->
<endpoint address="" binding="webHttpBinding" contract="empl.IService1" behaviorConfiguration="web">
<!--
Upon deployment, the following identity element should be removed or replaced to reflect the
identity under which the deployed service runs. If removed, WCF will infer an appropriate identity
automatically.
-->
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<endpointBehaviors>
<behavior name="web">
<webHttp/>
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior name="empl.Service1Behavior">
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="true"/>
<!-- 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="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
And my code "Web.config"for WCF WebRole (Azure)is as follow
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior>
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="true"/>
<!-- 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="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" /></system.serviceModel>
Now I need to get the URI access "http://localhost/Service1.svc/GetId" where it should respond in JSON data. But for me it is showing that "HTTP400 Bad Request". Help me out.

The bad request might be that the request being sent is not valid. If your service was not accessible or found it would have been a different Http error code. Try enabling tracing on your service to see the cause for bad request. To enable tracing follow this link

WCF and .NET 3.5: receiving large arrays

I am struggling to understand what I am doing wrong. I have a simple interface that accepts an array. I can't make it to handle more than ~150 items - getting back 400 Bad Request. What am I doing wrong? Can anyone spot anything? I looked thru this post and it appears to be the answer but it doesn't work for me: WCF maxReceivedMessageSize not being read from config.
The service is hosted in IIS7 and uses .NET 3.5. Here is my web.config:
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="MyService.basicHttpBinding" maxReceivedMessageSize="5000000" maxBufferSize="5000000">
<readerQuotas maxStringContentLength="5000000" maxArrayLength="5000000" />
</binding>
</basicHttpBinding>
</bindings>
<behaviors>
<serviceBehaviors>
<behavior name="MyService.Service1Behavior">
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="true"/>
<!-- Please set this to false when deploying -->
<serviceDebug includeExceptionDetailInFaults="True" httpHelpPageEnabled="True"/>
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service behaviorConfiguration="MyService.Service1Behavior" name="MyService">
<endpoint address="ws" binding="wsHttpBinding" contract="IMyService">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
<endpoint binding="basicHttpBinding" bindingConfiguration="MyService.basicHttpBinding" contract="IMyService" />
</service>
</services>
</system.serviceModel>

To troubleshoot turn on tracing both on the server and on the client, then inspect the log file. The error message points more to an object not being marked as [Serializable].
See http://msdn.microsoft.com/en-us/library/ms732023.aspx for guidance.

What's the config on the receiving end? I found the serializer blew up on receipt of lots of data.
