WCF cannot create custom endpointbehavior only in PROD environment

I have a WCF rest web service. Everything works fine on my development environment (#develop using IIS express), but i get the following error on my production evironment:

Server Error in '/Services' Application. --------------------------------------------------------------------------------

This is my web.config file:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.serviceModel>
        <services>
            <service name="AdvLinkForWebService.inbound">
                <endpoint address=""
                          binding="webHttpBinding"
                          contract="AdvLinkForWebService.Iinbound"
                          behaviorConfiguration="defaultWebHttpBehavior"/>

Solution

To run properly in my production evironment, it was necessary to specify the version, culture and key for inspectMessageBehavior. Ended up with the following configuration file:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.serviceModel>
        <extensions>
            <behaviorExtensions>
                <add name="inspectMessageBehavior"
                     type="AdvLinkForWebService.MessageInspector.InspectMessageBehaviorExtension, AdvLinkForWebService, Version=1.0.5791.17758, Culture=neutral, PublicKeyToken=null"/>
            </behaviorExtensions>
        </extensions>
        <behaviors>
            <endpointBehaviors>
                <behavior name="defaultWebHttpBehavior">
                    <webHttp/>
                    <inspectMessageBehavior/>
                </behavior>
                <behavior name="webHttp">
                    <webHttp/>
                </behavior>
            </endpointBehaviors>
        </behaviors>
        <services>
            <service name="AdvLinkForWebService.inbound">
                <endpoint address=""
                          binding="webHttpBinding"
                          contract="AdvLinkForWebService.Iinbound"
                          behaviorConfiguration="defaultWebHttpBehavior"/>
            </service>
            <service name="AdvLinkForWebService.config">
                <endpoint address=""
                          binding="webHttpBinding"
                          contract="AdvLinkForWebService.Iconfig"
                          behaviorConfiguration="webHttp"/>
            </service>
        </services>
    </system.serviceModel>
</configuration>

I don't know exactly how the version number is generated, even if it can be controlled, but I obtained it with the following command:

typeof(InspectMessageBehaviorExtension).AssemblyQualifiedName
