Hi,
I have several objects.
Can I keep them in memory and access the data when I need as .NET memory cache?

cache.add("key", myclass);
cache["key"].value...

I am using vs2019, c++20.
Where should I start to achieve this?

Thanks you!

    If you enable the “Common Language Runtime Support” (C++/CLI), then you can use the WeakReference and MemoryCache classes.

    In case of normal C++, I think that the automatic expiration and eviction of objects is problematic — it will require a specific redesigned allocation functions (malloc, new, etc.).

    Maybe you can develop your own cache for your large objects.

    Check some attempts too: https://www.bing.com/search?q=c%2B%2B+cache.
