Could you not create a wrapper around the parts of Microsoft's DNF that you need, providing the same functionality where it exists, but your own implementation where it doesn't?

namespace System
{
	// dummy for DNF so Slang can compile
	internal class ReadOnlySpan<T>
	{
		public override string ToString()
		{
			return null;
		}
		public int Length { get { return 0; } }
		public ReadOnlySpan<T> Slice(int position, int length)
		{
			return null;
		}
	}
}

string foobar = "foobar"

string bar = foobar.Substring(3,3); // string copy

string foobar = "foobar";
ReadOnlySpan<char> sp = (ReadOnlySpan<char>)foobar; // calls op_Implicit on string
ReadOnlySpan<char> sbar = sp.Slice(3,3); // no copy! this holding basically a pointer to "bar" in foobar

Deslang uses some reflection magic. And that magic is .NET Framework only.
