I have two controllers, both called AccountController. One of them, lets call it Controller A, is in an Area called Admin
Use this:
return RedirectToAction("LogIn", "Account", new { area = "" });
This will redirect to the LogIn action in the Account controller in the "global" area.
It's using this RedirectToAction overload:
protected internal RedirectToRouteResult RedirectToAction(
string actionName,
string controllerName,
Object routeValues
)
