❓ How does this help the contracts? (I never would have thought to include internal methods in the API contracts, but that doesn't mean they aren't useful.)

It does not help the contracts, but to understand what's going on here any why the contract must be this way.

💡 Thanks for clarifying. When I was reading through the code in the current form, I didn't feel like I understood exactly why Dispatcher could return null. If the comment for Dispatcher was updated in the way I mentioned in my other comment (on that property), I feel like this internal method and the preceding comment(s) could be removed from the code without reducing the clarity of this set of contracts, as freezing a Freezable is a well-understood concept for API consumers.

❓ Should this check against 0 as well?

Right, I've added this.

❓ Is this missing contracts?

Yes, I'll add them later.

❗ I'm fine with that as long as you create an issue. If the issue is narrow-scoped, it might make it easier for a new contributor to come along and add them. An example:
Add contracts for NotifyCollectionChangedEventArgs
A stub contract class for
NotifyCollectionChangedEventArgswas added in #84. The contracts for methods in this class still need to be added.
Then we can mark the issue with the up for grabs label. 👍

I have added the issue.
However it would be much easier if the one that finds a bug directly creates the issue 😄

First of all, this pull request was a massive improvement over #21, in terms of ability to focus the review on changes to contracts. Great job with that, I know it must have been a lot of work. 👍 You've given me a lot to think about. I'll be filing some "interesting issues" (IMO) as a result. Also 👍 for this. I'll read over the answers to the questions later today. |

❗ This is incorrect. It should be index < Count instead of index <= Count (the documentation above it needs to be corrected as well.
📝 Yes, MSDN is incorrect on this.

@SergeyTeplyakov any idea when you will merge this? @sharwell has reviewed it and I don't see any more concerns. |
