Application Packaging Interview Questions and Answers 2019 Part-1 | Application Packaging
Why does the package start self-healing the first time the user launches the application? Can you fix an application’s self-healing loop?
Self-healing is a method of checking an instal and starting a limited repair if required. A self-healing application can discern whether it works correctly and make the required changes to restore itself to the normal or designed state without human intervention. Knowing why self-healing happens and how to fix it if it gets into a loop shows your knowledge and technical proficiency in fixing common bugs. Address the two questions separately and in the correct succession. Provide brief and logical answers.
Example: A package may go for self-healing the first time the user launches the application if it contains some HKCU entries. This happens because the HKCU keys are only for the current user while installing the package and not for all users. Consequentially, if other users login, it causes a mismatch between the current system state and the value specified in the MSI package, which results in the related feature being re-installed.
There are numerous ways to fix an applications self-healing loop. You can send a no repair command from the command line or edit the MSI from within a packaging tool to disable self-repair.
