title: How to add a dll file into reference of Visual Studio properly?
body: <p>I know people normally add a dll file into the reference of Visual Studio very easily as follow:</p>
  
  <pre>
  1) Right Click on Reference
  2) Choose Add Reference
  3) Browse and choose dll file
  </pre>
  
  <p>However, with this approach, VS seems to store the absolute path, pointing to my dll file, rather than copy dll file into VS's project memory.</p>
  
  <p>What if I remove the dll file from the hard driver? or what if I want to deploy the project on another computer?</p>
  
  <p>Sorry, I am quite new to .Net</p>
