Func Injection in Unity

If you are using LinqToSql and dependency injection, then you have probably created a factory with which you create DataContexts. But what if you could just let your IOC Container do that work for you? You can! If you are using Unity then you can inject a Func<T> of any registered type. Unity will automatically bind the injected Func to the container's resolve method, thus preserving the resource Lifetime Manager.
