I think all of CTFE-D should map to .NET without much hassle.

struct ArraySlice<T>{
     private T[] storage;
     private ulong start;
     private ulong len;

     public ArraySlice<T> slice(ulong a, ulong b){
         if(a>b||b>len) throw new BoundsError("...");
         return new ArraySlice<T>(storage, start+a, b-a);
     }

     public ulong length(){ return len; }
     public Pointer<T> ptr(){ return new Pointer<T>(storage, start); }
     // ...
}

Performance will suffer of course.
