I'm trying to deploy a WCF hosted on my SharePoint site but I can't find the address where my web service is deployed.

I have a confirmation message which said that my web service is well deployed but I can't reach it!

So my sharepoint site is: http://Sharepoint/sites/pwa (it's a project site)

My web service is called Service1 and it builds in my namespace: Test.PS2016 I tried a lot of paths but I can't find my web service

It's still doesn't work, now I have a new issue, I saw the site but when I click on it I have an error message

So i have my ASP.NET Web Application which is called: Foo.PS2016.PSIExtension

With its iservice and Service (Very simple one):


namespace Foo.PS2016.PSIExtension
    interface IService
        bool isAlive();


namespace Foo.PS2016.PSIExtension

   [AspNetCompatibilityRequirements(RequirementsMode =     AspNetCompatibilityRequirementsMode.Allowed)]
   internal class Service : IService
    public bool isAlive()
        return (true);

its Service.svc:

<%@ ServiceHost Language="C#" Debug="true" Service="Foo.PS2016.PSIExtension.Service" %>

and its webservice:

*<?xml version="1.0" encoding="utf-8"?>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
    <compilation debug="true" targetFramework="4.5.2"/>
    <httpRuntime targetFramework="4.5.2"/>
      <add name="ApplicationInsightsWebTracking" type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web"/>
          <!-- 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="true"/>
      <add binding="basicHttpsBinding" scheme="https" />
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
    <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"/>

and I have my SharePoint solution with its folder ISAPI=>PSI=>Foo.PS2016.PSIExtension.svc :

The Version, culture and PublicKey comes from a powershell command from the file: Foo.PS2016.PSIExtension.dll

So I have been stucking on this issue since this morning so if someone has some ideas to help me

The _vti_bin is the built-in SharePoint Web services directory, it's not the default directory for the custom deployed web service.

To can deploy your custom WCF to this directory, you should add ISAPI as a mapped folder in your SharePoint solution

enter image description here

In this case, you can find your WCF below _vti_bin as the following

http://your site collection/_vti_bin/your web service folder/Service1.svc

Note: if you have added the web service under layout folder, so it's path should be this https://Sharepoint/Sites/pwa/_layouts/15/service folder/service1.svc

Alos please check this good reference to be able to Create a Custom WCF REST Service Hosted in SharePoint and Deployed in a WSP
