This project is probably of type WebSite and not a WebApplication, so it has a more limited set of options in VS. I am attaching a screenshot of the expected appearance of such a project as a reference here.
If you have it added to the IIS, then this is where you should configure its port through the Edit Bindings option from the context menu of the site where your project is added as a WebApplication (testingsite45 in the attached screenshots).
A site that uses our controls is not special, our controls only need a few HTTP handlers in the web.config and a few assembly references. Debugging and running them is not different than any other Web Site or Web Application in Visual Studio.
