The package 'StylerPackage' did not load correctly

[YannChv]

Hello,

Description of the issue

I'm working on a WPF/c# project on Visual Studio 2022 and I was using this extension, it worked perfectly. But, since I have updated my version of Visual Studio, I'm no more able to use the extension. This update have been made since a long time, at least more than 4 months now. At the beginning, I was thinking about an incompatibility between the versions. But, I start to think that the issue is elsewhere. Everytime I open a xaml file or the extension options, I get this error message :

The package 'StylerPackage' did not load correctly The problem may have been caused by a configuration change or by the installation of another extension. You can get more information by examining the file ...

Here is the error message I have in the ActivityLog file: SetSite failed for package [StylerPackage]Source: 'XamlStyler.Extension.Windows.VS2022' Description: Impossible de charger le fichier ou l'assembly 'Microsoft.VisualStudio.Threading, Version=17.5.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' ou une de ses dépendances.

I have already tried to uninstall and reinstall the extension and my Visual Studio version. But the problem remains the same.

Version Info:

• OS: Windows 11 professional 22H2
• Visual Studio: Microsoft Visual Studio Professional 2022 (64 bits) - LTSC 17.2 Version 17.2.23
• XAML Styler: XAML Styler for Visual Studio 2022 3.2311.2

Thank you,

I installed the same version of VS2022 on both my laptop and desktop, and both had the plugin installed. However, it can be used normally on a laptop, but not on a desktop. If you need me to provide information about the comparison of two computers, please let me know. I hope I can help fix this problem.

From the log above, it looks like you're using VS 17.2 but the extension is trying to load a version of a VS library from version 17.5

I'm not surprised that this causes an exception.

Yes, it seems to be the root cause of the issue. I've seen that you have opened a PR. Thank you for the time you took on it !

I hope there will be a fix in the coming days :)

Should be fixed with 3.2404.2 update.
