Hi,
I think DTF custom actions always need a Session object as parameter.With the
session object you can get installer properties.
Here is a example of a working C# CustomAction.
[CustomAction]public static ActionResult ConnectDb(Session session){ string
test = session["property"];}
<Binary Id="Custom.dll"
SourceFile="$(var.Custom.TargetDir)\$(var.Custom.TargetName).CA.dll"
/><CustomAction Id="ConnectDbAction" BinaryKey="Custom.dll"
DllEntry="ConnectDb" Execute="immediate" Return="check" />

Dick van den Brink
