title: How to build a licensing system in C#?
body: <p>The user will have to enter a licence key. That key will be writeten somewhere so that on the next application launch, the user won't be needed to insert it again. Let's say that the licence will be kept in a .txt file.</p>
  
  <p>In order to make this aproach more secure, my question is: how could I immediatly embbed that resource in the application after the user writes the key so that the file won't be visible in the app folder?</p>
  
  <p>Or maybe, is there any other way to somehow keep the key in the application after the user writes it and on the next executions, the app will still be able to see it?</p>
  
  <p>The "embed it like a resource" and read it from there the next time thing is just my idea, maybe there are other better ones.</p>
