I was watching a Silverlight tutorial video, and I came across an unfamiliar expression in the example code.

what is => ? what is its name? could you please provide me a link? I couldn't search for it because they are special characters.

code:

        var ctx = new EventManagerDomainContext();
        ctx.Events.Add(newEvent);
        ctx.SubmitChanges((op) =>
        {
            if (!op.HasError)
            {
                NavigateToEditEvent(newEvent.EventID);
            }
        }, null);
