This project references DoubleAgent.Control, which is a PIA for the COM objects
defined in DaControl.dll, which in turn loads DaCore.dll to provide the implementation.
To enable us to ship DaControl.dll without installing it, we need to implement registration
free COM activation. To do this, we need to call some Win32 APIs, namely CreateActCtx to
create an Activation Context that points to a manifest file that contains the registration
details for the COM objects in DaControl.dll.
