No, just wanted to report this
Mmh this seems like an external issue. @sharwell do you think this is some VS/Roslyn issue? Have you seen it before? 🤔
I haven't seen that before and I can't find any other feedback with that message. A performance recording using the Report a Problem feature should collect the information necessary to find the source of the exception.
@nickrandolph can you help with that? Feel free to share a link to the VS issue here for reference. Thank you!
FWIW, I've never successfully been able to add a RelayCommand or ObservableProperty w/ hot reload and MVVM toolkit / source generators. I seem to do more and more of my development with running processes so it's the source of some consternation.
apoloiges for the delay, will try to get repro this week
