Suprime .svc in URL of WCF-C# - wcf

Question

I start to work with WCF - C#, because I need to make a big scale project, and I found the follow problem:
I have tried to erase in the URL of a service WCF the .svc extension with following code:
using System.Web;
namespace PruebaWCFEndpoint
{
public class RemoveSvc : IHttpModule
{
public void Dispose()
{
}
public void Init(HttpApplication context)
{
context.BeginRequest += delegate
{
HttpContext ctx = HttpContext.Current;
string path = ctx.Request.AppRelativeCurrentExecutionFilePath;
path = path.Replace("Hola.svc", "Hola");
ctx.RewritePath(path, null, ctx.Request.QueryString.ToString(), false);
};
}
}
}
and the following code is the web.config:
<?xml version="1.0"?>
<configuration>
<appSettings>
<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true"/>
</appSettings>
<system.web>
<compilation debug="true" targetFramework="4.5"/>
<httpRuntime targetFramework="4.5"/>
<httpModules>
<add name="ApplicationInsightsWebTracking" type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web"/>
</httpModules>
</system.web>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior>
<!-- To avoid disclosing metadata information, set the values below to false before deployment -->
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="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>
<protocolMapping>
<add binding="basicHttpsBinding" scheme="https"/>
</protocolMapping>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true">
<remove name="ApplicationInsightsWebTracking"/>
<add name="ApplicationInsightsWebTracking" type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web"
preCondition="managedHandler"/>
<!--
The follow line was added by myself *************
-->
<add name ="removesvc" type="PruebaWCFEndpoint.RemoveSvc,PruebaWCFEndpoint"/>
<!--
******************************
-->
</modules>
<directoryBrowse enabled="true"/>
<validation validateIntegratedModeConfiguration="false"/>
</system.webServer>
</configuration>
But I am tring to test and the "WCF Test client" tool show the following message:
Error: Cannot obtain Metadata from http://localhost:9086/Hola.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 address.

The service interface is the follow:
using System.ServiceModel;
namespace PruebaWCFEndpoint
{
[ServiceContract]
public interface IHola
{
[OperationContract]
string saludar(string nombre);
}
}
and their implementation is the follow:
namespace PruebaWCFEndpoint
{
public class Hola : IHola
{
public string saludar(string nombre)
{
return "hola" + nombre;
}
}
}
