How to properly type nested Collections?

[svidskiy]

Hi! I'm working with an API response that has a nested array structure and I'm having trouble with proper typing using Collections.

The response structure looks like this:

{ "standings": [ [ { "id": 1 }, { "id": 2 } ], [ { "id": 3 }, { "id": 4 } ] ] }

I want to type this as a Collection of Collections containing DTOs. I tried:

Collection<int, Collection<int, SomeDto>>

But this doesn't work. What's the correct way to type nested Collections like this? Should I be using a different approach or is there a specific syntax for nested generic types that I'm missing?

Thanks for any guidance!
