Question

What is difference between unsafe code and unmanaged code in C#?

Answer 1

Unsafe - Code that can be outside the verifiable subset of CIL

Unmanaged - Code that is not managed by the runtime and is thus not visible to the GC (for example a native compiled x86 function would be unmanaged.)
