It’s safe, but you should do some testing yourself. I always set the
.Logproperty on my DataContext to log to the debug window. You may discover that you’re doing updates you didn’t intend to because the data has changed in a way you didn’t expect. It’s always good to watch what SQL is being generated and how many database calls are happening.
