. Static: The method can be static or non-static. Static Methods belong to a class rather than an instance. Therefore, just as we only have one separate class, we cannot have multiple copies of a static function. There is no constraint on where static functions can be created. Functions with the entrypoint command must be static. Static functions must have associated entities or source code and reference them using type names instead of instance names. Il managed: due to its complex nature, our
