Today, Microsoft released CRM SDK 4.0.12 - before you just download it and think its just another minor update - read on. This update includes what is being referred to as Advanced Developer Extensions. Before you stop reading saying "I'm not advanced" - "Advanced" I believe is marketing's way of saying this builds on top of the strong foundation that CRM already provided - not that you need to be a "Super Advanced" developer to use it. In reality, it's advanced because it's going to simplify how you interact with the CRM data. More specifically, it will allow you to use the LINQ expression syntax that developers have been using since C#3/VB9 to build queries.

In the past, CRM had specific types for CRM Boolean because at the time .NET didn't support nullable types.
