What is NOT a problem:
As always, I opned SQL Profiler and tried solve the issue but it misguided me by adding few extra zeros in millisecond part of datetime (I don't want to discuss it and it is not the problem).
What IS (or was in my case) problem:
I added an extra Datetime filed which was nullable in database. But I was mapping it to DateTime in my database. When NHibernate was converting my unset Datetime to SQLdatetime for mysterious reason, it was trying to set DateTime.Min in SQL datetime datatype which is not allowed (see exception).
Solution:
Look for any Datetime in your mappings that should be nullabe (according to database). And then use
type="System.Nullable`1[[System.DateTime, mscorlib]], mscorlib" in your mapping.
