New Post: Invoking managed actions that are in another class.

I created a public static class to keep all my EventLogInstaller actions separate from setup.cs. Then I tried referencing it, using both of these methods.

new ElevatedManagedAction("InitializeServerEventLog", Return.check, When.Before, Step.InstallFinalize, installServer),
new ElevatedManagedAction("EventLogInstaller.InitializeClientEventLog", Return.check, When.Before, Step.InstallFinalize, installClient),

Wix built an msi happily, however they would both cause an exception during installation like:

There is a problem with this Windows Installer package. A DLL required for this install to complete could not be run. Contact your support personnel or package vendor.  Action Action4_EventLogInstaller.InitializeClientEventLog, entry: EventLogInstaller.InitializeClientEventLog, library: C:\WINDOWS\Installer\MSI7D09.tmp 

If I move the methods to the Setup.cs:Script.Main method it works fine.

In your docs it says:

Managed CustomAction can be defined either in the Wix# script or in the external assembly or C# file. The only requirements for any C# method to be qualified for being Managed CustomAcyion is to have DTF Action signature public static ActionResult MyManagedAction(Session session), and be marked with [CustomAction] attribute. ` which I believe have done.

What am I doing wrong?
