Recently, the extension started to not work anymore (v4.0.583.0) while the Visual Studio 2022 version did not change (Version 17.14.0)

Typical modal window shown when VS loads and before I select a project to open. And is shown also when trying to access the extension from VS’s Extensions menu → DotVVM → About:
340 ERROR SetSite failed for package DotvvmPackage {1B39C66B-16E9-4B17-A90D-841357CC282C} 0x80131500 VisualStudio 2025/05/16 07:22:41.160

Please accept our apologies for the issue. The extension depends on some DLLs from Visual Studio, and every update makes some change so we have to rebuild it against the newest version of VS. We’ve just released the version 4.0.584.0, which should work with VS 17.14.

If you use Visual Studio 2022 Preview, download the correct build from the Release notes page.
