C#'s unsafe code is not native or unmanaged code - it is managed code 
that allows the use of pointers into the GC heap.  C# only interops with 
C code through runtime marshalling.  It does not interop with native C++ 
code - such code has to be recompiled through Microsoft's "Managed 
Extensions for C++" compiler, after much tinkering albeit.

I'll bet that if you were to take the time to convert your existing C++ 
library over to .NET you'd find you'd spend the same amount of time as 
you would creating a C API wrapper around such code for D to use.
