How does the .NET kernel work in multiple environments?

Question

How does a .NET server manage to run the same DLL on multiple operating systems?

Now I want to install .NET core in the environment where you want to run the application.

But I do not quite understand the work that the .NET kernel actually does under the hood.

Will he compile the native one before the first run or will he interpret each command and execute each command in the base system?
