How to detect changes in 1 entity framework object

I have a list of entities and when some entities change I just perform the following:

DBContext.SaveChanges();

and all modifications are saved.

but now I have to perform some business logic when certain entities are changed (and only for the ones that are changed) and need to find those changed entities. But I can't seem to be able to do this.

I've come across this post: Entity Framework 5 - Why is Entity State "Modified" after PropertyValue is set back to Original

where someone checks the .EntityState property ....

But my entity does not have this property.

As a last resort I could use INotifyPropertyChanged on the level of my model, but would be nice if EF5 would let me know the state of that entity.

To check the state of an entity use the following:

DbEntityEntry entry = Context.Entry(entity); //where Context is DbContext or derived

// entry.State is available here
