Raising events on separate thread

Question

I am developing a component which needs to process the live feed and broadcast the data to the listeners in pretty fast manner ( with about 100 nano second level accuracy, e

You can use these simple extension methods on your event handlers:

public static void Raise(this EventHandler handler, object sender, T e) where T : EventArgs {
    if (handler != null) handler(sender, e);
}

public static void Raise(this EventHandler handler, object sender, EventArgs e) {
    if (handler != null) handler(sender, e);
}

public static void RaiseOnDifferentThread(this EventHandler handler, object sender, T e) where T : EventArgs {
    if (handler != null) Task.Factory.StartNewOnDifferentThread(() => handler.Raise(sender, e));
}

public static void RaiseOnDifferentThread(this EventHandler handler, object sender, EventArgs e) {
    if (handler != null) Task.Factory.StartNewOnDifferentThread(() => handler.Raise(sender, e));
}

public static Task StartNewOnDifferentThread(this TaskFactory taskFactory, Action action) {
    return taskFactory.StartNew(action: action, cancellationToken: new CancellationToken());
}

Usage:

public static Test() {
     myEventHandler.RaiseOnDifferentThread(null, EventArgs.Empty);
}

The cancellationToken is necessary to guarantee StartNew() actually uses a different thread, as explained here.
