Sometimes, it might be handy to not have VS.NET pick a dynamic port each and every time it starts Visual Web Developer Web Server (aka ASP.NET Development Server or, as it was called back in the old days, Cassini). There is an easy way to get a fixed port when you press Ctrl+F5. First step is to select the Web project in Solution Explorer:
Next, go to the Properties window (DO NOT right-click and choose Property Pages - you will end up somewhere entirely different):
As you can see, I already switched "Use dynamic ports" to False, and in this case, I chose to stick with the default provided port number. When is this port-setting useful? When you automate tests, for example.
