It is defined as static. It may be good idea to rename it to s_listenPort (see coding style) to express that explicitly:

@joao-gueifao-924 are you interested in putting up a PR to change the sample?
It could use also some code formatting changes if you're at it (4 spaces for indentation, interpolated strings, etc.)

Regardless of the full example appearing to be correct, that variable simply does not appear at all in the documentation page. I believe that renaming it will be of little help (yes, even prefixing it with "s_" to refer it is a static variable).

I am not interested in putting a PR. Microsoft team can do that. I already paid the necessary licenses for my usage of the product.
