pure mode versus mixed mode

I do not get the difference between these two modes. I read that pure
mode produces code that uses IL instructions only. Does that mean a
mixed mode EXE might have native code and IL code? How does that
work?

Is the following correct:

1. In pure mode: If you have managed classes and native code
(unmanaged classes), it all gets compiled to IL.

2. In mixed mode: If you have managed classes and unmanaged classes,
the managed classes compile to IL and the unmanaged classes get
compiled to native code.

I don't know the details, I've never needed to know, it just works!

There are restrictions on "pure". Have a look at the MSDN topics
titled "Mixed, Pure, and Verifiable Feature Comparison " & "Converting
Projects from Mixed Mode to Pure Intermediate Language".

Yes.
