| 47 | <p>A sample CA project with two CAs is included in the | ||
| 48 | Samples\ManagedCA directory. 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. | ||
