.NET and Java Editions

The .NET and Java editions of /n software components are thread safe, and component methods can be called from separate threads. The component does not guarantee that cross-thread calls will be correctly synchronized, however, and if the component is busy when a cross-thread call is made it will result in an error.

Further, under certain conditions, calling component methods from within a component event handler can lead to a deadlock. It is recommended in these cases to instead schedule the work inside of the event handler and perform the work after the event returns.

C++ Edition and Other Editions

All other editions are not thread safe. Components should be used only on the thread in which they were instantiated.
