Metadata is currently disabled on my WCF svc page - vb.net

Question

The following is my web.config file:
<?xml version="1.0"?>
<configuration>
<appSettings>
<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
</appSettings>
<system.web>
<compilation debug="true" targetFramework="4.5" />
</system.web>
<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="false" multipleSiteBindingsEnabled="true" />
<bindings>
<webHttpBinding>
<binding name="Binding" crossDomainScriptAccessEnabled="true">
<security mode="Transport">
<transport clientCredentialType="None" />
</security>
</binding>
</webHttpBinding>
</bindings>
<client />
<services>
<service name="Service1" behaviorConfiguration="ServiceBehaviour">
<endpoint address="" binding="webHttpBinding" contract="Service1"/>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="ServiceBehaviour">
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="ServiceBehaviourJSON">
<webHttp helpEnabled="true" defaultOutgoingResponseFormat="Json" />
</behavior>
</endpointBehaviors>
</behaviors>
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
<!--
To browse web app root directory during debugging, set the value below to true.
Set to false before deployment to avoid disclosing web app folder information.
-->
<directoryBrowse enabled="true"/>
</system.webServer>
</configuration>
And I viewed a few examples of this error on here and changed what was asked but I still seem to get the same Metadata publishing for this service is currently disabled.??
My two files for the web service are called IService1.vb and Service1.svc.
Maybe someone can see the error that I can't and let me know :)
Updated web.config file

You expose metadata using HTTP protocol (httpGetEnabled), then WCF seeks for address to expose but there is no HTTP base address defined, alas.
