Does anyone know how to get the generic type of List<List<T>>? I'd first have List<List<T>> but parsing that would go to List<T> and then T. But I'm getting null in the second operation

Depending on where you get that type from the type information might not be present.

I've ended up doing the TypeReference and creating and object containing all that information at runtime. I'm still struggling a little bit with the Wildcard and Parameterized Types but yeah, working on it.
