Implementing INotifyPropertyChanged - does a better way exist?
...er with C# 5:
protected bool SetField<T>(ref T field, T value,
[CallerMemberName] string propertyName = null)

Check if one IEnumerable contains all elements of another IEnumerable
What is the fastest way to determine if one IEnumerable contains all the elements of another IEnumerable when comparing a field/property of each element in both collections?
