# CanAutoDetect

> Any extensions marked as IFormatter.CanAutoDetect will be called implicitly (when no formatter name is specified in the input format string). For example, "{0:N2}" will implicitly call extensions marked as IFormatter.CanAutoDetect. Implicit formatter invocations should not throw exceptions. With IFormatter.CanAutoDetect == false, the formatter can only be called by its name in the input format string.
