You don't need to mess around with TIME_WAIT to accomplish what you want.

The problem is that you are disposing the WebClient every time you call Execute(). When you do that, you close the socket connection with the server and the TCP port keeps busy for the TIME_WAIT period.

A better approach is to create the WebClient in the constructor of your HttpGetTest class and reuse the same object throughout the test.

WebClient uses keep alive by default and will reuse the same connection for all its requests so in your case there will be only 100 opened connections for this.
