You could also try replacing the line: cmd.Parameters.Add("@p0", 0); with: cmd.Parameters.AddWithValue("@p0", 0); The reason that new AddWithValue method was added in .NET 2.0 was precisely because of the ambiguity caused between the Add(string, object) and Add(string, *DbType) overloads. If that fixes the problem (I suspect it will), the bug is with NHibernate - it shouldn't be calling the Add(string, object) overload anymore... or, if it needs to work with .NET 1.1 as well, then it should use a different overload of Add().
