Assuming that you’re comparing it to a local variable reference, there is no difference whatsoever; both will emit the exact same IL. (At least in Release mode)
However, if you’re comparing it to repeated invocations of a property or indexer,
Withwill be a little bit faster, and if you’re comparing it to repeated invocations of a method, it might be much faster. (TheWithkeyword will create a local variable and assign it to the object that youWith‘d, so the method will only be called once instead of on every line)
