Add basic authentication to WCF Service hosted in a Windows service

Question

How can I add basic authentication to a WCF service hosted in a Windows service?

I added a security tag to my binding, but I don't get an authentication window when I call the service url in the browser. What am I doing wrong/what am I missing?

<bindings>
  <basicHttpBinding>
    <binding name="MyDefaultBinding" allowCookies="true" maxReceivedMessageSize="20000000" maxBufferSize="20000000">
      <readerQuotas maxDepth="500" maxArrayLength="20000000" maxStringContentLength="20000000"/>  
    <security mode="TransportCredentialOnly">
       <transport clientCredentialType="Basic" />
   </security>
    </binding>
  </basicHttpBinding>
</bindings>

You will not get that authentication window when you just access the service helper page. The authentication is configured for service endpoint - not for helper page or WSDL (those are "separate endpoints").

Try to modify your configuration:

<bindings>
  <customBinding>
    <binding name="securedPages">
      <textMessageEncoding messageVersion="None" />
      <httpsTransport authenticationScheme="Basic" />
    </binding>
  <customBinding>
  <basicHttpBinding>
    <binding name="MyDefaultBinding" allowCookies="true" maxReceivedMessageSize="20000000" maxBufferSize="20000000">
      <readerQuotas maxDepth="500" maxArrayLength="20000000" maxStringContentLength="20000000"/>  
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Basic" />
      </security>
    </binding>
  </basicHttpBinding>
</bindings>
