I need to get a reference to an Umbraco Macro from another Macro - and I've found the generic control with a recursive search. However, I now need to cast it to an Umbaco Macro and I can't for the life of me find the namespace 'umbraco.presentation.templateControls.Macro'

I've included these directives:

using umbraco.cms.businesslogic.macro;

using umbraco.DataLayer;

using umbraco.BusinessLogic;

Casting using businesslogic.Macro gives a casting error - wrong type.

Help appreciated.
