@m-chau we marked CrytpoKeyGenerator.GenerateKey as obsolete, as mentioned in these patch notes and linked to the PR with reasoning here. The gist is:

1. The underlying .NET method that enabled this was removed after .NET 4.7.2. As we've added new .NET targets, we don't have an implementation for it.
2. This helper method was not part of our core API. The reason for it being included before is unclear, but it seems mainly for testing purposes. We believe we shouldn't have such APIs in the client and therefore have chosen not to find a new implementation for newer .NET targets.
