ICustomTypeDescriptor for simulating strong-typing

I thought about simulating strong-typing for key-value configuration of a new project by providing fake property info via implementing ICustomTypeDescriptor.

The configuration instance should provide all default config keys as properties with default values however: I noticed that VS08 intellisense doesn't include "faked" properties which are created in example similar to

Even if I intellisense caches properties information, I used a static instance of the MyCustomClass in another class in a dll and still didn't get intellisense working for it.

ICustomTypeDescriptor never provides a type-safe interface, so I cannot see how it can ever provide Intellisense.
