Anders was primarily focused on C#. He contributed greatly to some of the pre-FX frameworks (WFC), but once the VJ++ injunction happened, MS was very focused on getting a modern language out into the world. The part that you are referencing was part of the CLR (nee COM+) organization. This native compilation didn't happen for a couple of reasons: 1. Serviceability - the idea was that we wanted to be able to roll out new assemblies with fixes (remember this was in the "oh shit" phase of security awareness at MS) 2. Optimizations - there was an idea that you wanted different JIT to happen based on end machine architecture, server vs client, etc. 3. Size - at this point the size of the resulting binaries (for distribution) was still a concern. At that point it seemed better to have fat frameworks updated by Windows Update, and smaller apps that depended on that. Many of these reasons seems less compelling now. MS was often a bubble in those days. I left in 2012 but it seems better now and it shows in their products.
