title: Add DLL in ASP NET Web Service
body: <p>Today I added DLL in my ASP NET Web Service.I found two ways to add DLL.</p>
  
  <p><strong>First one is</strong> - Right click on project &lt;&lt; Add Reference &lt;&lt; Browser &lt;&lt; Select the DLL.</p>
  
  <p><strong>Second one is</strong> - Right click on bin folder &lt;&lt; Add Existing Item &lt;&lt; Select the DLL.</p>
  
  <p>Both are working fine.So now my question is "<strong>Is there any difference between both ways?</strong>"</p>
  
  <p>If yes then please do reply.</p>
  
  <p>Thanks in advance.</p>
  
  <p>Regards,
  Mohit Kumar.</p>
