title: Abp boilerplate Localization by QueryStringRequestCultureProvider for custom language
body: <p>I try to use localization method <code>L()</code> in <em>MyController</em> for getting localization string from my <em>custom added language</em>(not standart for boilerplate - swedish).</p>
  
  <p>Regarding to documentation (<a href="https://aspnetboilerplate.com/Pages/Documents/Localization" rel="nofollow noreferrer">https://aspnetboilerplate.com/Pages/Documents/Localization</a>)
  I can add <strong>queryStringParameter</strong> to request <code>culture=sv</code> (my source localization file is <code>Abp-sv.xml</code>)
  I added this parameter but <code>L("SomeString)</code> returns localization for default language.</p>
  
  <p><strong>If I use culture for standart ASP.NET Boilerplate languages ar, de, etc. then it works.</strong></p>
