47 <p>A sample CA project with two CAs is included in the
48 Samples\ManagedCA directory.&nbsp; Running the CustomActionTest project will package the CA and insert
49 it into a test MSI. The MSI will invoke the custom actions, but it will not install anything
50 since the second sample CA returns ActionResult.UserExit.
