Hey @ArgoZhang - I've reviewed your changes - here's some feedback:

Overall Comments:

• Consider implementing the Keys property for all .NET versions instead of limiting it to NET9_0_OR_GREATER. You can enumerate the keys manually for earlier versions to provide consistent functionality across framework versions.
