If anyone is using Visual Studio 2017 and IIS and is trying to debug a web site project, the following worked for me:

1. Attach the web site project to IIS.
2. Add it to the solution with File -> Add -> Existing Web Site... and select the project from the inetpub/wwwroot directory.
3. Right-click on the web site project in the solution explorer and select Property Pages -> Start Options
4. Click on Specific Page and select the startup page (For service use Service.svc, for web site use Default.aspx or the custom name for the page you selected).
5. Click on Use custom server and write

http(s)://localhost/(web site name as appears in IIS)

for example: http://localhost/MyWebSite

That's it! Don't forget to make sure the web site is running on the IIS and that the web site you wish to debug is selected as the startup project (Right-click -> Set as StartUp Project).
