Method OnPropertyChanged for exposed property is called with old value about catel.fody

[GeertvanHorrik]

Thanks for reporting and the detailed error report. I will investigate this ASAP. Do you have a repo that I can use? E.g. do you have this code in a public repo?

@Green7 I have written a unit test, but cannot reproduce. Can you double check the unit test is correct?

I added an extra check to check both the model and view model values:

the problem occurs if the variable is bound in UI.
I used the code:
<TextBox Text="{Binding SelectedThemeName, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />

In such a situation, OnSelectedThemeNameChanged is called with the old value of AppSettings.SelectedThemeName.
But surprisingly, if we use the dynamic object (as in the example), it will show the new, correct value.

Then it's probably the RaisePropertyChanged, I will try to reproduce this inside a unit test.
