title: How to run IdentityServer3 samples?
body: <p>It is hard for me to complitly uderstand how works identoty server 3.
  Even when I spent lot of time to investigate.
  Now I am trying to run <a href="https://github.com/IdentityServer/IdentityServer3.Samples/tree/master/source/Clients" rel="nofollow">IdentityServer3 samples</a>.</p>
  
  <p>I can run client (for example: <strong>WPF Implicit Client</strong>), but I cannot login when I run this.</p>
  
  <p>I assume that I have to run two more projects</p>
  
  <ul>
  <li>Project which host identity server (place where clients and scopes are registred)</li>
  <li>and also api project.</li>
  </ul>
  
  <p>When I try to run <strong>'Sample Web API'</strong> project I get error:</p>
  
  <blockquote>
    <p>An exception of type 'System.InvalidOperationException' occurred in
    IdentityServer3.AccessTokenValidation.dll but was not handled in user
    code</p>
    
    <p>Additional information: IDX10803: Unable to create to obtain
    configuration from:
    '<a href="https://localhost:44333/core/.well-known/openid-configuration" rel="nofollow">https://localhost:44333/core/.well-known/openid-configuration</a>'.</p>
  </blockquote>
  
  <ul>
  <li><p>So probably still missing identity server project but I don’t know
  where is this project? (I am talking about project  with
  localhost:44333).</p></li>
  <li><p>Also do I need to set certificate somehow? </p></li>
  </ul>
  
  <p>I tryied so many things and
     still nothig.
  Can you please help me to run this examples. Because this does not
     work when just download solution.</p>
  
  <p>It would be great if someone knows steps what need to be done to make semples work.</p>
  
  <p>Thanks for help.</p>
