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

Overall Comments:

• Using reflection to access private members of MemoryCache is fragile and may break in future .NET versions. Consider adding error handling and documenting this implementation detail as a potential maintenance risk.

Here's what I looked at during the review
