Did you create a full DTF custom action project or just add the references/attribute to a normal c# one?
A DTF custom action dll has the c# dll embedded in it as a resource with a manifest file...

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" /> Regards, Dick van den Brink > From: [email protected] > To: [email protected] > Date: Wed, 20 Apr 2011 14:09:05 +0000 > Subject: [WiX-users] C# CustomAction DLL won't run? > > Hi Guys, > > I've been writing a custom-action for detecting if a given feature is installed on the machine.
