title: Where is SigningCertificate and RequireSsl in AddIdentityServer method identity server4
body: <p>According to <a href="http://elemarjr.com/en/2016/04/18/learning-identityserver4-part-1-securing-an-webapi/" rel="nofollow noreferrer">this</a> article i can access <code>SigningCertificate </code> and <code>RequireSsl </code> in <code>ConfigureServices</code> method in <code>Startup</code> class:</p>
  <pre><code> var builder = services.AddIdentityServer(options =&gt;
          {
              options.SigningCertificate = certificate;
              options.RequireSsl = false; 
          });
  </code></pre>
  <p>I do as it said but i got error:</p>
  <blockquote>
  <p>'IdentityServerOptions' does not contain a definition for 'SigningCertificate' and no extension method 'SigningCertificate' accepting a first argument of type 'IdentityServerOptions' could be found (are you missing a using directive or an assembly reference?)   NewIdentityServer..NETCoreApp,Version=v1.0  2015\Projects\NewIdentityServer\src\NewIdentityServer\Startup.cs</p>
  </blockquote>
  <p>how can i access these properties?</p>
  <p>NOTE: I use  identity server version:  <code>&quot;IdentityServer4&quot;: &quot;1.1.0&quot;,</code></p>
