title: VB.NET functions stored in external files
body: <p>I'm trying to make a program that call its functions stored in some other file <strong>not compiled into the main executable file</strong>. For example, there are two functions <code>Copy File</code> and <code>Delete File</code> and I want to add one more function <code>Rename File</code> without changing the code and compiling again.</p>
  
  <p>I want to achieve it by adding a file/module of the new function <code>Rename File</code>.</p>
