        {
            // Change in Customer, Customer.FirstName or
            // Customer.PrincipalAddress.Line1 will trigger the event.
            return string.Format("{0} {1} from {2}",
                Customer?.FirstName,
                Customer?.LastName,
                Customer?.PrincipalAddress?.FullAddress);
        }
    }

DOCUMENTATION

Command

[NotifyPropertyChanged]
public partial class MainWindow : Window
{
    bool isReadOnly;

    [Command]
    public ICommand SaveCommand { get; private set; }

    private void ExecuteSave()
    {
        // Details skipped.
    }

    public bool CanExecuteSave => !this.isReadOnly;
}

Stop creating a class every time you define a command.

Easy, based on custom attributes and naming conventions.
Validated at build time.
CanExecute property integrates with the [NotifyPropertyChanged] aspect.

DOCUMENTATION

Code Contracts

public interface IReferralService
{
    [return: Required]
    Referral CreateReferral([Required] string name, [Url] string url);
}


public class ReferralService : IReferralService
{
    public Referral CreateReferral(string name, string url)
    {
        // Contracts are automatically inherited from the interface.
    }

    [Required]
    public string ConnectionString { get; set; }
}

The most readable way to validate values at run-time.

Works with parameters, output parameters, return values, fields, and properties.

As fast as hand-written code.
Customizable and localizable exception messages.

DOCUMENTATION

Weak Event

static class MyEventSource
{
    [WeakEvent]
    public static event EventHandler MyEvent;
}


class MyEventClient
{
    public MyEventClient()
    {
        MyEventSource.MyEvent += (sender, e) => Console.WriteLine("Oops!");

        // No need for IDisposable and handler unregistration.
    }
