They have been present in MSI and App-V packaging formats for ages, while for MSIX, they were introduced and supported about a year after Microsoft announced the MSIX release.

Nowadays CI/CD(Continuous Integration and Continuous Delivery) pipeline became a best practice for developers and DevOps helping them to manage the software process in a much easier and automated way.

A firewall is a network security system that can be found on any modern operating system. It's purpose is to act as a barrier against network-based intrusions, to monitor and control incoming and outgoing traffic following an organization's predetermined security rules.

Release management and version control go hand in hand when delivering quality software, whether you are a solo developer or part of a development team.

Digital signing is an important stage of an application packaging cycle and can be achieved by code signing your own software’s certificates. By digitally signing your software, you prove your application’s authenticity and integrity upon installation and guarantee that the software you developed hasn’t been compromised or corrupted.

To help with the MSIX transition, Microsoft has released the Package Support Framework (PSF) - an open-source framework that enables you to apply runtime fixups for issues that might appear when migrating legacy applications that you don’t have the source code for.

You've finished building your MSIX application, and it's time to share it with the rest of the world.

Although not necessarily common practice, there are some instances where you would want to prevent users from uninstalling specific MSIX packages such as monitoring software that is required to gather data from all employees.

MSIX Modification Package is a type of MSIX package format introduced by Microsoft with the goal of decoupling customizations from the main application.
