Just been trying to convert my app from Windows Phone 8.0 to Windows Phone 8.1 Universal/store app.
I was using Devart's LinqConnect to access my SQLite database and when I added the model to the project and did a compile and I received the following error.
Error 1 The type or namespace name 'INotifyPropertyChanging' could not be found (are you missing a using directive or an assembly reference?)
Has I INotifyPropertyChanging been remove from wp8.1?
Update 1:
A few people have mentioned that it should be in System.ComponentModel namespace.
I just had quick look and intellisense say this is valid
System.ComponentModel.INotifyPropertyChanged
but this is not
System.ComponentModel.INotifyPropertyChanging
INotifyPropertyChanging is not used by Windows Runtime apps (Store or Phone). It is not present in the .Net Framework for Windows Store apps. The best way to tell if something is present is to use Visual Studio's object browser since it will read the live metadata.
It is available for Windows Phone Silverlight apps.
If you have legacy code which implements it you may be able to stub that out by creating your own INotifyPropertyChanging definition. This will work within your own code, but you'll need to remove any behavioural dependencies on system code calling it.
