title: Update one DLL file in an ASP.NET website project
body: <p>net development. I am working in a website project and I am trying to update one of the dll files. I've search for hours for a solution on stackoverflow, but no luck. </p>
  
  <p>Our website project in Visual studios is composed of one website that uses three C# projects. I am trying to update just one of these C# projects. Currently the website is in production and the DLL files of these projects are in the /bin folder. </p>
  
  <ol>
  <li>I opened up the solution in VS and made my changes.</li>
  <li>I built the whole solution and retrieved the new dll.</li>
  <li>I stopped our in-process website with IIS and overwrote the dll and restarted it again.</li>
  </ol>
  
  <p>I get an Missing Method Exception as an error when I do this. I was hoping for a straight forward way of updating our website project because I only need to change about two lines of code and swapping dll files seems like the easiest way of doing this.</p>
  
  <p>Thank you guys for your help and be patient with me I am a slow learner and I ask a lot of questions.</p>
