Is System.Security.CodeAccessPermission obsolete in .NET Core 3.1 / .NET 5.0?

Question

I know that CAS is obsolete in .NET Core 3.1 / .NET 5.0 .

Is System.Security.CodeAccessPermission also obsolete? I was unable to find any reliable information about it on Internet. The documentation don't say anything about it, and just a few methods - like the Deny() method - are marked as obsolete on the docs .

Assuming that they are all obsolete - and that's why I couldn't find any current articles or books about it, - what should I use instead? Can you please point me to some docs or books that discuss the current state of code access security on .NET Framework 4.8 / Core 3.1 / 5.0? I couldn't find any!

Thanks!

There can be significant delay between code change and documentation update. So we should focus on the code first, which is available on GitHub . From there we can see this type only becomes obsolete in .NET 5.

To migrate away from obsolete types, you can follow the guide .
