.NET MPI implementation?

Question

What is the most mature .NET MPI implementation? A quick google search turned up the two below, but I'm not familiar with either of them. I believe the first item (mpi.net) is based on Microsoft MPI. Any thoughts?

MPI.NET's FAQ says

On Unix, however, MPI.NET adapts itself to the native MPI detected at configure time, and can work with (at least) Open MPI, LAM/MPI, and MPICH2.

although on Windows it appears to be a completely managed solution. AFAICT, Pure Mpi.NET is only a managed solution.

I haven't used either of these implementations -- in fact, it's been a while since I've used any MPI -- but I would suspect that MPI.NET has a higher likelihood of overall stability since it will actually use the "tried-and-true" Unix implementations when available. Those Unix implementations have been in the field for a much longer time, and as such are generally less likely to be buggy -- or at least if there are bugs, they are probably well-known by now.
