The Package Support Framework (PSF) was originally a Microsoft open-source project to help Win32/DotNet applications run when inside an MSIX Container. TMurgent has taken up the support for the PSF in our own fork here on GitHub.
Version v2026.02.22 of the Package Support Framework released today.
It mostly consists of logging changes, but a couple of things:
- New informational intercepts around apps that dynamically alter the dll search directory list. Hoping to find out why some apps still miss their dlls.
- Fix to the AddDllDirectory to handle longer directory strings that occur in packaged apps.
- Changes in process launching to react to badly formed program requests that we can figure out what the app really wanted.
It is up on GitHub today. Will be in tools that use the PSF shortly. Check their release notes about what version they are using.
For those unaware, PSF stands for Package Support Framework, an open-source utility that I contribute to for helping traditional Win32 and DotNet applications run inside the MSIX packaging container. This article contains information regarding new contributions.
