If you wire up an installer class CA in VDPROJ and edit the resultant MSI in
Orca you'll see that you are actually getting 2 CA's for each CA. Was is a
Type 51 CA that's setting a property with the same name as the second deferred
CA. This is the serialization of properties that the installcontext is
deserializing for you.
So for DTF, whether it's WiX or InstallShield or whatever, you need an
immeadiate CA that serializes and sets the property that will become
CustomActionData and then in your deferred CA you need to deserialize it.
The serialization looks something like this: ( shoot from hip coding, not
tested )
CustomActionData cad = new CustomActionData();
cad.Add( new KeyValuePair<"PROPA","VALUEA");
session["DeferredCustomActionName"] = cad.ToString();
The deserialization looks something like this:
CustomActionData cad = new
CustomActionData(session["CustomActionData"]);
string valuea = cad["PROPA"];
BTW, in case Jason is reading, maybe I'm missing something but the constructor
choices for the CustomActionData class could probably be a little better. The
CustomActionData property is always `CustomActionData` so maybe there should be
an overload that takes the session class as an argument and automatically gets
the CustomActionData property.
I hope that helps.
