title: Hooking into an "OnLoad" for class library
body: <p>Does anyone know if there's a way to hook into an "OnLoad" event to run some operations when an assembly loads?</p>
  
  <p>Specifically, I am creating a plug-in for an application. The plug-in's DLL gets loaded and objects start being used, but the problem is I need to load another assembly dynamically before anything happens. This assembly can't be copied to the application's directory and must remain invisible to it.</p>
