title: Where DLL file should be place in .NET web application
body: <p>In a C# ASP.NET Web Application I'm structuring it with the web application on the top, and then multiple projects for handling business layers and a data access layer. I have a DLL file that contains SQL Helper.  Should that be placed in the bin of the Web Application or a folder I create named 'lib' in the root of the Web Application. </p>
  
  <p>Lastly since it is a DLL dealing with data access should I place it in the project containing the data layer classes that will be referencing that DLL and if I do how should I place it in that project(type class library). </p>
  
  <p>Thanks for all the considerations.</p>
