I assume that because one can say that an IoC-container is about requesting previously registered services.
I don't think there is one (or should be) having this weird name. This sounds like part of the 'magic', or maybe it's something that LinqToSQL thinks it should have by the sheer law of nature...

We all know that null, when compared with anything, returns false. Even null=null evaluates to false. But I was amazed to see that null!=Value also returns false.
