>>You do need to use DateTime.Now but the point is that it has less precision than DateTime2(7) SQL Server. My question is there another .NET structure that provides the same precision as DateTime2? The Help mentions StopWatch class http://msdn.microsoft.com/en-us/library/system.diagnostics.stopwatch(v=vs.110).aspx but it's not clear how to apply it to obtain current time with high precision.

>Yes, DateTime.Now as is would stop at the millisecond precision. I took at look at that page. As you said, it is not cleary visible as to know what has to be done. We do have this nano precision in .NET. The question is how to upscale it up to a SQL Server DateTime2 field.

In my code I think I always use DateTime.Now
