Thanks for the change. Is there any way we could put this deep compare behind a flag or use it in a different methods names besides Equals? This is a really costly change that would have a significant performance impact. Also, in .NET the Equals method is intended to work differently depending on whether you have a reference or value type. This change considers all objects to be value types, so changing from reference equality to value equality could be surprising to consumers.

See the remarks section here for details: https://docs.microsoft.com/en-us/dotnet/api/system.object.equals?view=netframework-4.7.2

@jimschubert thanks for the review and feedback. I'll add an option to let users choose which one to use.
