This .NET class wraps the AcadApp::LoadReasons ObjectARX enum. 

That enumerated type contains reasons to demand load an application.

Public Enum ApplicationLoadReasons
  LoadDisabled = &H10
  OnAutoCADStartup = 2
  OnCommandInvocation = 4
  OnLoadRequest = 8
  OnProxyDetection = 1
  TransparentlyLoadable = &H20
End Enum

public enum ApplicationLoadReasons {
  LoadDisabled = 0x10,
  OnAutoCADStartup = 2,
  OnCommandInvocation = 4,
  OnLoadRequest = 8,
  OnProxyDetection = 1,
  TransparentlyLoadable = 0x20
}
