title: Localization in external class libraries in ASP.NET Core
body: <p>I have two projects:</p>
  
  <ul>
  <li><strong>MyWebApp</strong> - ASP.NET Core Web API </li>
  <li><strong>MyServices</strong> - .NET Core class library,
  which contains helpful services for project above</li>
  </ul>
  
  <p>How can I add localization with <code>IStringLocalizer</code> to <strong>MyServices</strong>? Where must be <code>.resx</code> files located?</p>
