With Windows 8 RTM out of the doors (at least for some of us), it was also time to create an update to MVVM Light. I selected the V4 RTM to do this (V4.0.23).This RTM version was released a few weeks ago with no much bells and whistles because I was just too busy to write much about it. Now after some vacation, I will resume blogging on all my favorite topics including of course MVVM Light.


Upgrading the installations should not require an ununistall, so try to simply run the MSI downloaded from the Download section at http://mvvmlight.codeplex.com/. Should you encounter any issue, try to uninstall the old version first following the steps at https://galasoft.ch/mvvm/cleaning/.

Upgrading current apps from Win8 RP to Win8 RTM

I didn’t recompile the assemblies of MVVM Light, so if you had a version running with V4.0.23 on Windows 8 RP, you should be able to use the same DLLs on Windows 8 RTM. If you were using earlier versions however, I would recommend doing an upgrade.

I noticed a warning regarding the signing certificate. It is due to the PFX key which appears to be outdated after the upgrade to Windows 8 RTM. I solved this warning by replacing the old PFX key with a new one I copied from a new project. The warning did not cause the build to fail though.

About MVVM Light V4 RTM

The RTM is finalizing quite a lot of issues. The change log is available at https://galasoft.ch/mvvm/installing/changes/. There are some issues that are either still open or that popped up since then, and I am working on V4.1 to be released in the next few weeks.

In addition to that, I have plans to support Windows Phone 8 (when it comes) and have a nice list of ideas for V5 with a few new components.

Thanks again for your continuous support of MVVM Light!
