WCF IMetadataExchange Error - wcf

Question

I have created a service host with following configuration.
<?xml version="1.0"?>
<configuration>
<system.serviceModel>
<services>
<service name="MathServiceLib.MathService" behaviorConfiguration="myMathServiceBehave">
<host>
<baseAddresses>
<add baseAddress="http://localhost:9001/MathService"/>
<add baseAddress="net.tcp://localhost:9002/MathService"/>
</baseAddresses>
</host>
<endpoint address="http://localhost:9001/MathService" binding="basicHttpBinding" contract="MathServiceLib.IMathService"/>
<endpoint address ="net.tcp://localhost:9002/MathService" binding ="netTcpBinding" contract="MathServiceLib.IMathService"/>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
<!--<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange"/>-->
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="myMathServiceBehave">
<!--<serviceMetadata httpGetEnabled="true"/>-->
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
I don't want to use serviceMetadata httpGetEnabled="true" property instead I want to use MEX binding for proxy creation.
Now when I start my service using
svcHost = new ServiceHost(typeof(MathServiceLib.MathService));
svcHost.Open();
I get following error, please help.
The contract name 'IMetadataExchange' could not be found in the list of contracts implemented by the service MathService. Add a ServiceMetadataBehavior to the configuration file or to the ServiceHost directly to enable support for this contract.

Answer 1

Based on my experience, you need to specify
<serviceMetadata httpGetEnabled="true"/>
if you want to use
<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange"/>
