How to make WCF Service Use HTTPS protocol

Question

I have a WCF service which works as rest and soap. I am trying to receive requests via HTTPS protocol but I can't no matter what I've tried.

I've tried to modify the web.config file according to this post:

How to enable HTTPS in WCF service

I've tried couple of other similar methods I've found on the web. But no matter I do, I always get: "Could not find a base address that matches scheme http for the endpoint with binding WSHttpBinding. Registered base address schemes are [https]." error upon running the project on debug mode.

My configuration is as follows:

  <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="SendEmailSoap" />
        <binding name="SendSMSSoap" />
        <binding name="KPSPublicSoap">
          <security mode="Transport" />
        </binding>
        <binding name="KPSPublicSoap1" />
      </basicHttpBinding>

      <webHttpBinding>
        <binding name="WebBinding">
          <security mode="None">
            <transport clientCredentialType="None" />
          </security>
        </binding>
      </webHttpBinding>

      <wsHttpBinding>
        <binding name="WsBinding">
          <security mode="None" />
        </binding>
      </wsHttpBinding>

    </bindings>

    <behaviors>
      <endpointBehaviors>
        <behavior name="web">
          <webHttp />
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior name="servicebehaviors">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
        <behavior name="">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
        <behavior name="integrationServiceBehaviour">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="false" />
          <serviceDebug includeExceptionDetailInFaults="false" />
          <serviceCredentials>
            <userNameAuthentication userNamePasswordValidationMode="Custom" customUserNamePasswordValidatorType="KaporaWebService.App_Code.CustomValidator, App_Code" />
          </serviceCredentials>
        </behavior>

      </serviceBehaviors>
    </behaviors>
    <services>
      <service behaviorConfiguration="integrationServiceBehaviour" name="KaporaWebService.IntegrationService">
        <endpoint address="/ws" binding="wsHttpBinding" bindingConfiguration="WsBinding" contract="KaporaWebService.IIntegrationService" />
        <endpoint address="" behaviorConfiguration="web" binding="webHttpBinding" bindingConfiguration="WebBinding" contract="KaporaWebService.IIntegrationService" />
      </service>
    </services>
    <protocolMapping>
      <add binding="basicHttpsBinding" scheme="https" />
    </protocolMapping>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="false" />
  </system.serviceModel>

What do I need to do enable HTTPS on WCF?

We are supposed to add additional service endpoint which uses transport layer security, and add https binding in IIS site binding module. Please see my configuration.

<system.serviceModel>
    <services>
      <service behaviorConfiguration="mybehavior" name="WcfService1.Service1">
        <endpoint address="" binding="webHttpBinding" contract="WcfService1.IService1" behaviorConfiguration="webbev"></endpoint>
        <endpoint address="" binding="webHttpBinding" contract="WcfService1.IService1" behaviorConfiguration="webbev" bindingConfiguration="mybinding"></endpoint>
        <endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange"></endpoint>
      </service>
    </services>
    <bindings>
      <webHttpBinding>
        <binding name="mybinding" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" transferMode="Streamed" sendTimeout="00:10:00" receiveTimeout="00:10:00">
          <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" />
          <security mode="Transport">
            <transport clientCredentialType="None"></transport>
          </security>
        </binding>
      </webHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name="mybehavior">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="webbev">
          <webHttp />
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>

Here is the simplified configuration since WCF has the new feature in net4.5

  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior>
          <webHttp />
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <bindings>
      <webHttpBinding>
        <binding name="mybinding">
          <security mode="Transport">
            <transport clientCredentialType="None"></transport>
          </security>
        </binding>
      </webHttpBinding>
    </bindings>
    <protocolMapping>
      <add binding="webHttpBinding" scheme="http"/>
      <add binding="webHttpBinding" scheme="https" bindingConfiguration="mybinding"/>
    </protocolMapping>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>

Then add https address and specify the certificate.
