Originally created by @SabrinaMH on GitHub (Dec 11, 2018).

I'm using WireMock in an NUnit test, where I spin up a server on port 9002. At the end of the test (and in case of exceptions) I make sure to shut down the server using the following lines of code:
server.Stop(); server.Dispose();

However, the port is still in use, cf.

which means that I cannot run the test again.

How do I release the port?

You cannot release the port manually. It's done by the OS.
This can take some time.

In your case the best is to use a dynamic port in each uni-test (see also my unit-tests in this project)

Thanks for the reply!
I actually thought that the app needed to put the socket into TIME_WAIT in order for the OS to be able to know that it is not User anymore.
