Hi, I got the error the package did not load correctly on Visual Studio 2022.
Please check it. Thanks!
I’m having the same error, also in VS 2022.
The tool does nothing. 
This most likely happens because the DotVVM extension isn’t compatible with the specific VS version, last update should support Visual Studio 17.9.4 or 17.10.0 Preview 2.0 (Release notes | DotVVM Documentation). Unfortunately, Microsoft is constantly breaking the VS extension API, sometimes even across patch versions, without any heads up to extension developers.
Can you please try downgrading? If that doesn’t help, please post the mentioned ActivityLog.xml file, or just the last exception(s) from this file
EDIT: I looked into the release notes, which told me that the newest version of VS is actually supported. 17.9.6 was probably never supported, then? Apologies for bumping this thread.
Original post:
I get this same error now, at the end of 2024. Visual Studio is of version 17.9.6, and the extension is unable to load. Any help on maybe installing version 17.9.4 in order to make it work? Or are there updates on the way, or workarounds, for the plugin to work?
