I want to change the port number on which my website runs while debugging from Visual Studio. I am using Visual Studio 2012, and I am using ASP.NET MVC 4 for my projects I want to change the port. Random port or fixed anyone will work just want to change the port.
To specify a port for a Web application project that uses IIS Express
In Solution Explorer, right-click the name of the application and then select Properties. Click the Web tab.
In the Servers section, under Use Local IIS Web server, in the Project URL box change the port number.
To the right of the Project URL box, click Create Virtual Directory, and then click OK.
In the File menu, click Save Selected Items.
To verify the change, press CTRL+F5 to run the project. The new port number appears in the address bar of the browser.
