Visual Studio mark as error every property of class that inherit by ObservableObject

Question

I have two clsses that inherits by ObservableObject. In the second class I use the first, but Visual Studio mark as error every his property as by attached image. If I run the app, it work fine.

I use CommunityToolkit.Mvvm 8.1 version in a Winui3 app.

I guess this is related to this known [issue](https://github.com/CommunityToolkit/dotnet/issues/598). — Andrew KeepCoding, Feb 20 '23 at 03:51
It seems to be an Intellicode issue on Visual Studio. We have to wait until they fix it. Meanwhile we can just ignore it. — Andrew KeepCoding, Feb 22 '23 at 06:41

It seems that this is not a problem in the CommunitToolkit.Mvvm NuGet package. See here and here.

The CommunityToolkit.Mvvm is working so you can just ignore these warnings for the moment until this get fixed.

As a temporary workaround, try using v8.0, restart Visual Studio and see if the warnings are gone.
