Add warning message for incorrect usage of [Reactive]

[luojunyuan]

[Reactive] public bool IsVisible { get; set; }

This will not generate any code.

[Reactive] public partial bool IsVisible { get; set; }

This is correct, but when I mistakenly write it in the first way, there seems to be no error or warning.

Can we have a warning or hint for this kind of misuse.

I agree, I would very much welcome this feature. I migrated from ReactiveUI.Fody and missed changing a few properties to partial and I didn't catch the mistake until things weren't working at runtime.

I will look at adding an analyser for this, thank you for the feedback.
