Event Notification Generator

[GenerateEventNotification] creates a typed EventNotification<TEvent, TKey> factory from key, rule, correlation, and metadata methods.

[GenerateEventNotification(typeof(OrderAccepted), typeof(string), NotificationName = "order-accepted")]
public static partial class OrderAcceptedNotification
{
    [EventNotificationRule]
    private static bool ShouldNotify(OrderAccepted evt) => evt.NotifySubscribers;

    [EventNotificationKey]
    private static string Key(OrderAccepted evt) => evt.OrderId;

    [EventNotificationCorrelation]
    private static string Correlation(OrderAccepted evt) => evt.CorrelationId;

    [EventNotificationMetadata("source")]
    private static string Source(OrderAccepted evt) => evt.Source;
}

Diagnostics:

PKEN001: host type must be partial.
