title: Dynamically add files for localization C#
body: <p>I need a help in localizing my Wpf .net 3.5 application. I am going to give only the exe file to my cient with which he will create setup for his users. My client wants to add files for localization by himself.</p>
  
  <p>The general method of localization is creating .resx files for each languages and set the language in CurrentUICulture. but since, he cant use resgen tool to create resource files, I want to know the best method to let him add files in txt,excel,xml format to make the localization.</p>
  
  <p>PS: reading through stream and assigning the key is the only way?</p>
