Visual Studio IIS Express hangs on launch, but IIS local works, why?

Question

I run Visual studio 2015 as administrator, start a new project, ASP.NET application, Empty 4.5.2 and then just add a simple html page. When I try to launch using IIS Expres

Answer 1

Sometimes Visual Studio just takes many minutes to load all the required symbols when debugging. Check the status bar of Visual Studio:

Once for some reason IIS Express worked if I changed the browser targeted in Visual Studio to Google Chrome. Simply restarting Visual Studio fixed this for me though.

Answer 2

Solution:
1. Run VS as Administrator. Open your sln, Start debugging, stop and close the VS.
2. Again open the sln (without admin) file and start debugging.
It worked!

Problem:
- My VS2017 was running fine with debugging, until some other tool's installation corrupted it. Then I reinstalled it. When I started debugging/running site, it wasn't even opening first page of site. It was keep loading assemblies forever. I tried many things found on google. It didn't help.
- Finally I tried opening it with Admin and then regular. It solved my problem.

Look into applicationhost.config file under

YOUR_DOCUMENTS_PATH\IISExpress\config\

Localize defaultDocument setting and add your static html page full name (yourpage.html) or use one of the options available if you want to stick to the standards:

   <defaultDocument enabled="true">
        <files>
            <add value="Default.htm" />
            <add value="Default.asp" />
            <add value="index.htm" />
            <add value="index.html" />
            <add value="iisstart.htm" />
            <add value="default.aspx" />
        </files>
    </defaultDocument>
